I was just about to file an SR – and quick search shows that someone else has already had this problem.

OBIEE 10.1.3.4 is Not Supporting Excel 2007 – File you are Trying to Open is in a Different Format than Specified by the File Extension – Contain Features not Compatible [ID 980627.1]

OBIEE 10.1.3.4
Microsoft Windows x64 (64-bit)

- Oracle OBIEE 10.1.3.4 is not supporting MS Office 2007.

- We are trying to download a report from answers to Excel 2007 but its downloading as Excel 2003.
- Why is it?

- After clicking Download -> Download to Excel, in the request, saving the file and then trying to open it in 2003, the following message appears:

”
Microsoft Office Excel

The file you are trying to open, ‘Test.xls’, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
[Yes][No][Help]
”

If I click on Yes button, I am able to open the report.

If I update some values and try to save then I get a warning message:

”
Microsoft Office Excel

test.xls may contain features that are not compatible with Single File Web Page. Do you want to keep the workbook in this format?

- To keep this format, which leaves out any incompatible features, click Yes.
- To preserve the features, click No. Then save a copy in the latest Excel format.
- To see what might be lost, click Help.

[Yes][No][Help]
”

I have to click on Yes button then it can be saved.

I should update and save this 2003 excel type on excel 2007 without any warning message.

- In Citrix, If I use Download -> Download to Excel and click on open button to open the file, I get this popup:

”
Windows Installer

Preparing to install…

[Cancel]
”

and that ends up with error:

”
D:\TEMP\…\Temporary_Internet_Files\Content.IE5\STMP6X8Z\Test.xls

Only Administrators have permission to add, remove, or configure server software during a Terminal services remote session. If you want to install or configure software on the server, contact your Network Administrator.

1. Excel 2003 documents can be opened in Excel 2007.

2. From Release Notes OBIEE 10.1.3.4.1:
(“http://download.oracle.com/docs/cd/E10415_01/doc/bi.1013/e10404/toc.htm)
”
4.1.18 Limitation on the Number of Rows in MS Excel 2007
This issue applies to Versions 10.1.3.3, 10.1.3.3.1, 10.1.3.3.2, and 10.1.3.3.3. It is fixed in version 10.1.3.4.

In Microsoft Excel 2007, users cannot insert views that have more than 65536 rows. This is because Oracle BI Office uses an Excel 2003 based template, which has a limit of 65536 rows per sheet.
”

So, template used is for Microsoft Windows Excel 2003.

3. There is an Enhancement Request already filed asking to use an Excel 2007 template.
It is Document Bug 6970162, “Abstract: DOWNLOAD TO EXCEL REQUIRES TRANSLATION WHEN OFFICE 2007 INSTALLED”.

It is set to be reviewed for future versions. It has not yet been approved to be included in a particular version.

4. About the error you get when you try to open the downloaded file, in Excel 2007:

”
Microsoft Office Excel

The file you are trying to open, ‘Test.xls’, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?

It is an Excel 2007 issue.

ORACLE cannot  be responsible for giving you solutions for Microsoft Excel Issues, as it is not our area.
You could google the error.
Nevertheless, we are giving you an example of one of the documents available in Google for that error. Please, be aware it is being given as a guideline, if you want to try it.

There is a descdription and some workarounds provided at:

http://www.itexperience.net/2008/03/17/excel-2007-error-different-format-than-specified-by-the-file-extension/

where they say:
”
This errors particularly occurs when you’re trying to open an XLS file (Excel 2000-2003) with Excel 2007. In most cases, the problem can be solved by defining MIME types and associating them with extensions.
When you’re using a Document Management System (like Sharepoint or Livelink), you can try adding these:
.xls = application/msexcel
.xlsx = application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

However, if you don’t want to look for a solution, but just want to solve the problem, insert this key in your registry to suppress the notification:

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security]
“ExtensionHardening”=dword:00000000

You can accomplish the above by doing the following:

Open your Registry (Start -> Run -> regedit.exe)
Navigate to HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\12.0\EXCEL\SECURITY
Right click in the right window and choose New -> DWORD
Type “ExtensionHardening” as the name (without the quotes)
Verify that the data has the value “0?
”

You could talk to your Microsoft Excel Support to verify the workarounds given above, or to provide another solution.

5. About the error you get once you modify the file in Excel 2007 and try to save it:

”

It seems to be due to OBIEE using mhtml when exporting to Excel.

There is an Enhancement Request already filed, Document Bug 5661454, “ABILITY TO GET EXCEL VIEWER WORKING WITH ‘DOWNLOAD TO EXCEL’”, requiring changing Excel download from MHTML to native Excel format.
It has been approved to be included in OBIEE 11.1.1.2.0.

Document Note 749436.1, “Download to Excel from reports downloading as HTML/MHTML rather than ‘real’ Excel”, explains more about that.

Having said that, the following document provides some information on the error when trying to save files with some formats in Excel 2007 (again, it is not an ORACLE article, so we are giving it only as a guide):

http://office.microsoft.com/en-us/help/hp100141051033.aspx

They say:
”
The Microsoft Office Excel 2007 Workbook format (.xlsx) preserves all worksheet and chart data, formatting, and other features available in Office Excel 2007, and the Macro-Enabled Workbook format (.xlsm) preserves macros and macro sheets in addition to those features.

If you frequently share workbook data with people who use an earlier version of Excel, you can work in Compatibility Mode to prevent the loss of data and fidelity when the workbook is opened in the earlier version of Excel, or you can use converters that help you transition the data. For more information, see Use Office Excel 2007 with earlier versions of Excel(http://office.microsoft.com/en-us/help/HA100775611033.aspx).
…
…
…
Web Page and Single File Web Page
These Web Page file formats (.htm, .html), Single File Web Page file formats (.mht, .mhtml) can be used for exporting Excel data. In Office Excel 2007, worksheet features (such as formulas, charts, PivotTables, and Visual Basic for Application (VBA) projects) are no longer supported in these file formats, and they will be lost when you open a file in this file format again in Excel.
”

6. About the other errors you get on Citrix:

”
Windows Installer

Preparing to install…

[Cancel]
”

and

”
D:\TEMP\…\Temporary_Internet_Files\Content.IE5\STMP6X8Z\Test.xls

Only Administrators have permission to add, remove, or configure server software during a Terminal services remote session. If you want to install or configure software on the server, contact your Network Administrator.

[Ok]
”

You would need to verify them with your Citrix Support, as they cannot be reproduced outside Citrix. The error text seems to say you do not have permissions to write in the TEMP directory for IE to create a temporary Excel file. It is a Windows issue also, apparently.

If you had problems using EVALUATE function -  please look at the following SR that I just found. Apparently, the work-around is to use CAST function.

QL Request: SET VARIABLE QUERY_SRC_CD=’Report’,SAW_SRC_PATH=’/users/administrator/last_working_day test 1′;SELECT “Task Type”.Type saw_0, “Task – Creation Date”.Date saw_1, EVALUATE(‘num_of_working_days(%1,%2)’,”Task – Creation Date”.Date,”Task – Last Updated Date”.Date) saw_2, “Task – Last Updated Date”.Date saw_3 FROM “SPS – Operation” ORDER BY saw_0, saw_1, saw_2, saw_3

The query fails and the following error occurs.

ERROR
———————–
Query Status: Query Failed: [nQSError: 46035] Datatype(DOUBLE PRECISION) nullable(1) unicode(1) external char(0) conversion to datatype(TIMESTAMP) nullable(1) unicode(0) external char(0) is not supported.

These columns are from W_DAY_D. These are type date which the function is expecting. The function returns a number.

BUSINESS IMPACT
———————–
The issue has the following business impact:
Due to this issue, this is holding up resolution of a critical issue on the delivery of the project – which plans to go live next Friday (30th October).

Cause

Comments
——–
The cause of this issue is that EVALUATE expects to return data with a data type that is the same as the data
type of the parameter.
This has been raised in : EVALUATE FUNCTION SHOULD RETURN DATA TYPE OF FUNCTION

The Bug explains that when you use this function:

EVALUATE(‘my_function(%1)’, logical_table.ROWID)

It will set the data type of the column to INT because ROWID is also INT. However my_function does not return an INT but a REAL.

============================
The above is what you are experiencing and why you get the error suggesting converting double precision to timestamp is not supported

[nQSError: 46035] Datatype(DOUBLE PRECISION) nullable(1) unicode(1) external char(0) conversion to datatype(TIMESTAMP) nullable(1) unicode(0) external char(0) is not supported.

Proposed Solution

Customer was asked to do an explicit CAST to set the datatype to the datatype of the value that will be returned by my_function.

So something like

CAST(EVALUATE(‘my_function(%1)’, logical_table.ROWID) AS FLOAT)

The above resolved the issue.

There’s an interesting discussion about IIS and OC4J on OTN- OC4J discussion

I think there’s a lot of confusion as to what is a difference between web server and web application server (apparently web server just serves static HTML (it can also server PHP/ASP pages), however, doesn’t run applications — on the other side – it’s tough to distinguish between dynamic web applications written in script languages and Java container OC4J). If you

I think that it’s clear from the discussion that OBIEE requires IIS (in Windows server) and OC4J is an quasi-optional module for BI Publisher and Scheduler.

Another thing -check your connection pool settings. According to Oracle, BI Server might crash if there’re “Several Connection Pools in the custom RPD had ‘Execute Queries Asynchronously’ enabled. This is no longer recommended in OBI 10g as it can cause the OBI EE (NQServer) Server to crash.”

This is addressed in Bug No.BUG 7634602 – ‘OBI SERVER CRASH – 3-818156441′

Symptoms
After migration from 10.1.3.2.1 to 10.1.3.4 Prompt selection window not rendering correctly when a Multi Select Prompt is created for OBI EE Dashboard Prompts.

In Answers, On clicking to go to the selector screen for the Multi-Select Prompt, in it we see on the right:
match: begins with…. the right side is empty. Also the left side (‘Selected’) is empty.
So, No values display in the list.

Details:
- Customer has tried entering a value in the textbox and clicking go, nothing happens.
- The issue does not happen on customers 10.1.3.2.1 instance. It only happens on their 10.1.3.4 instance which they have migrated from 10.1.3.2.1.
- Web Server is Apache\Tomcat 5.5
- Java version is JDK 1.5.18

Steps to reproduce:

- Log into Answers
- At top of left Answers window select ‘New Dashboard Prompt icon, & select a subject area
- from the list on the left select a dimension (eg Calendar Month Desc)
- change Control to ‘Multi-select’
- select ‘Constrain’
- change Defaults To to ‘Specific Value’
- from that list select a value
- top right of screen select the Preview icon
- next to default value, select the icon to bring up the Multi-select window.
- the issue is seen here, no values in the list.
Cause

Client migrated from 10.1.3.2 to 10.1.3.4. During the migration they replaced the ‘res’ folder with the copy from their 10.1.3.2 version and then regenerated the war file. The same war file was deployed in Tomcat.

This is the root of the problem. The ‘res’ folder should not be copied from the older version instance.
Solution

Obtain a fresh 10.1.3.4 ‘res’ folder and replace the copied 10.1.3.2.1 version with that.

I thought this might be useful for someone struggling with Essbase.

Client was on OBI 10.1.3.4.0 QF 170 and Oracle’s Hyperion Essbase 9.3.1 and running a report in Answers based on ASOSample Essbase cube which is generating an error.

In Answers Customer has created a report with a measure column (selected twice) which is being filtered with 2 different values using the filter function as below:

Add the 1st column
a. In Answers, Navigate to the Criteria Tab,
b. Select the column “Original Price”
c. On the column, click ‘edit formulae’,
d. in the edit formulae box, click the ‘Filter’ button
e. Insert a filter for the column, by selecting from the selection pane
column “Products”.”Product SKU” = ‘Boomboxes’.
.
Add the second column
Repeat the above steps a-d
In step e, Insert a filter for the column, by selecting from the selection pane column “Products”.”Product SKU” = ‘DVD’

The report can also be generated by directly entering the following SQL in Advanced Tab
select
Filter( Sample.”Original Price” using “Products”.”Product SKU” = ‘Boomboxes’ ),Filter( Sample.”Original Price” using “Products”.”Product SKU” = ‘DVD’ )
from ASOSamp

————–
When the report is run the error message that is generated is as below

Query Failed: [nQSError: 42043] An external aggregate is found in an outer query

The MDX generated is

With
set [Products5] as ‘{[Products].[Boomboxes], [Products].[DVD]}’
set [Axis1Set] as ‘crossjoin ({[Age3]},crossjoin ({[Attribute Calculations2]},crossjoin ({[Geography5]},crossjoin ({[Income Level2]},crossjoin ({[Payment Type2]},crossjoin ({[Products6]},crossjoin ({[Promotions2]},crossjoin ({[Stores4]},crossjoin ({[Time5]},crossjoin ({[Transaction Type2]},{[Years2]}))))))))))’
select
{[Measures].[Original Price]} on columns,
NON EMPTY {[Axis1Set]} properties ANCESTOR_NAMES, GEN_NUMBER on rows
from [ASOsamp.Sample]
Cause

By default in the OBI rpd, the Aggregation rule is set to “External Aggregation”. As per Engineering this needs to be change, so OBI EE knows what those rules are.

Filter By clauses are not supported by MDX (or Essbase), so OBI EE has to perform those internally. If the Aggregation rule is set to “External Aggregation”, then OBI EE doesn’t know what those rules are and hence throws this error.
Solution

It is possible to fix the error by doing the below

1. Changing the OBI Aggregation rule in both the Physical and BMM layer to the corresponding rule in Essbase, would stop the error.

2. Alternatively, using OBI Answers filter clauses would allow the BI Server to re-write the MDX to push down the filter to Essbase and may be more efficient anyway.

There was an enhancement raised within Oracle to address this matter in a future release, as the client stated that changing the aggregation rule in the rpd is not a suitable option.
