Maximum Number Of Columns For A OBIEE Pivot Table?

Hi All ,
What is the Maximum Number of Columns for a OBIEE Pivot Table? Also what is default size of columns set for Pivot view in OBIEE 11g?
Thanks In Advance.

Hi,
You can increase the maximum columns in a view by add some tags to instanceconfig.xml file.
check this...http://obiee101.blogspot.com/2008/02/obiee-controling-pivot-view-behavior.html

Maximum Number of Columns for Control Break on APEX Reports

Hi
I'm new to APEX. I just want to ask if the number of maximum columns for control break in Reports can be adjusted? I have noticed that it can only handle up to six columns for Control Break, I just want to know if it can have more than six columns.
Thank you very much.

Are you sure it's the number of columns? It may be one of the columns that is causing this problem.

Maximum number of columns for BDC

Hye all,
I am doing upload program to upload data from CSV file into MM01. Since there will be many columns in my CSV file (24 columns consists of material master data), does BDC programming has any limitation with regards to the number of columns that can be uploaded into MM01 screen?
Thanks in advance.

Dear Seshu,
Thanks for your reply. Right now, I don't know why my uploading doesn't work accordingly. The first few windows and tabs worked just fine. When it reached column number 16 in the CSV file which need to be uploaded into tab # 5, the data is not being uploaded. At first, I suspected there are limitation of number of columns.
By the way, below are my BDC code for tab # 5:
    perform begin using 'SAPLMGMM' '4000' 'X'.
    perform info using 'BDC_OKCODE' '=SP05'.
    perform info using 'BDC_CURSOR' 'MVKE-KONDM'.
    perform info_tc using 'MVKE-KONDM' wa_data-c16.
    perform info_tc using 'MVKE-KTGRM' wa_data-c17.
    perform info_tc using 'MVKE-PRODH' wa_data-c18.

Maximum number of columns for a SQL report

I am trying to pull a single report for approx 180 - 360 columns per row from a table with 30 columns (6 to 12 months data). The report is then to be exported to csv and then merged into a Word document. Due to the limitation of 100 columns in html db this cannot be done.
We cannot merge direct from the database. Is there another method to get data into Word or out of the database that I have not thought of?

Hi Arvind,
You are correct in saying that only 50 columns can be shown in the BW report at a time. It will allow you to place more than 50 fields in the query definition but the query will not execute.
If you want to show more than 50 columns, you can add those extra columns in the FREE CHARACTERISTICS of the query definition. So at the time of execution of the query user will see the 50 columns by default and if he wants to see those additional columns, he can replace the already existing columns by the fields in the free characteristics. This can be achieved by DRILL DOWN and DRILL ACROSS.
This is the way to go about it. We also did the same thing in our case.

Maximum Number of Entries for Upload in Custom Table

Hi All,
I have a requirement to create a custom table, and then a custom program will be used to upload the data entries. The user is expecting to upload more than 5000 entries at one load. However, the program is encontering a dump. Is there a maximum number of entries which can be uploaded via foreground execution?
Is there any other way to upload more than 10,000 entries at one execution?
Thanks,
Louisse

Hi,
No restrictions for number of records to be upload in custom table.
You have to go to technical settings, there select Size category for number of data records of table expected.

Maximum number of columns in List for InfoPath to customise?

What is the maximum number of columns I can have in a list to be able to customise it with InfoPath?
We have ~180 columns in our list, and it was working before with ~80, however it's now failing with "The
SOAP message cannot be parsed" error. Please see my StackExchange Error post
here.
So just wondering if InfoPath can't handle too many columns? Or perhaps IIS is killing the message because the XML packet sent to the service is too large?
Update: I increased all IPFS settings in Central Admin ten-fold, but I still got the same error.
Update: As per my StackExchange post - I saved the list as a blank template and was able to customize the list with InfoPath and publish the changes. Seems it could also be data-related. The current list has ~1000 items in it.

Hi Peter,
Please try adding the executionTimeout="3000" in your SharePoint site web.config file (please back up the original file firstly) per the following article, then check result again (restart the IIS if needed),
http://sharepointshah.blogspot.com/2012/11/soap-message-cannot-be-parsed-error.html
If the issue still happens, you can check if there are more related errors in ULS log like this
article.

ORA 01792 maximum number of columns in a table or view is 1000

Hello every1, I wish to register a large xmlschema doc, I am using the command
begin
dbms_xmlschema.registerschema(
schemaurl=>'xxxx',
schemadoc=>bfilename('XMLDIR','xxxxxx.xsd'),
csid=>nls_charset_id('AL32UTF8'));
end;
But the schema file exists 1000 col and it gives me the error msg of
ORA-01792: maximum number of columns in a table or view is 1000
is there anyway to solve the problems without edit the original schema document?

I am trying to create a direct link from Tririga / Oracle database into Crystal XI. The data I am attempting to pull is from the RETransaction (Escalations). The error I keep receiving is shown below. Has anyone run across this problem and found a solution that can be shared?
Very Appreciative for any feedback.

Try posting your software, its version, and the type of connectivity you're using for oracle.
Older versions of Crystal used a proprietary Oracle ODBC driver that came with Crystal, but you should SWITCH away from using ODBC anyway, not sure why you elected to use it, it's slower and more problematic.
You'll see Oracle Server listed as a data source, that is generally the best connectivity to use.
Also, what version of Oracle is it, and what Oracle client are you using?
You might need your Oracle dbas assistance here.
Anyway, the error is not a Crystal error, it's being raised by the ODBC driver, and Oracle used to have a maximum of 1024 colums I think it was...been a while...

Sort key too long - maximum number of columns in select statement

the sort key too long is caused by either too many group
functions or too many columns selected. Does anyone know the
maximum number of columns that can be selected in one statement ?

The Oracle 9i reference states ...
The GROUP BY expression and all of the
nondistinct aggregates functions (for example,
SUM, AVG) must fit within a single database
block.
... and the Oracle 9i SQL Reference states that ...
An order_by_clause can contain no more than 255
expressions.
You could check your own documentation, but i think it will
be the same.

please help!!!

Hi All,
After all R&D it is been found that Oracle business administrator( RPD) needs default dbo schema. It doesn't accept custom schema for pulling data.
If anybody have other views please share.!!
Thank you

What is the maximum number of columns available in Numbers 3.1?

What is the maximum number of columns available in Numbers 3.1? (I don't seem to be able to get past Column IU. Is that just how it is?)

What is the maximum number of columns allowed on a table?

What is the maximum number of columns that a table can have? I have a research team that wants to have 140,000 columns on one table and 2000 rows.
What would be the best way to input (SQL*Loader?) that data on this table and retrieve data from this table? The highest number of columns that I have implemented on a table was 500.
Any feedback would be greatly appreciated.
Thanks. ;-)

Holy cow 140,000 columns and 2000 rows!! I think you are going to have to tell someone to come up with a better design because that doesn't sound like a relational table. Besides, I found this in the Oracle 8.1.7 Reference Manual:
"The absolute maximum number of columns in a table is 1000. However, when you create an object table (or a relational table with columns of object, nested table, varray, or REF type), Oracle maps the columns of the user-defined types to relational columns, creating in effect "hidden columns" that count toward the 1000-column limit. For details on how Oracle calculates the total number of columns in such a table, please refer to Oracle8i Administrator's Guide."

Registerschema gives ORA-01792: maximum number of columns...

Hi,
DB: Oracle9i Enterprise Edition Release 9.2.0.6.0
Opp Sys: HP-UX
I've just increased the size of an XSD we have loaded in a customers database and attempting to reload using dbms_xmlschema.registerschema gives the following error:
ORA-31084: error while creating table "SOLO"."LetterRoot5799_TAB" for element "LetterRoot"
ORA-01792: maximum number of columns in a table or view is 1000
ORA-02310: exceeded maximum number of allowable columns in table
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 26
ORA-06512: at "SOLO.WORK_TEST_LETTERS_XSD", line 23
ORA-06512: at line 2
Is there a work around for this?
Thanks,

Hi! I faced the same problem as author of a thread. At first it was just the same and I used solution that was offered - add attribute xdb:SQLInline="false".
But now this error (ORA-01792: maximum number of columns in a table or view is 1000) became to rise on element that doesn't have a lot of attributes or subelements that coul exceed limit of 1000! Moreover it is based on complex type that already exists! It was created during another schema registration, which is included in schema that I'm trying to register now!
Does anyone challenged this problem?
I use Oracle9i Enterprise Edition Release 9.2.0.5.0

Maximum number of rows for an ALV

Dear all,
What is the maximum number of columns an ALV grid can handle .
Best Regards,
Manmohan.

Hello Manmohan,
As far as I know the total column size for a list screen is 1023 characters. ALV is actually making use of list screen instead of a dynpro. So as long as your total size of column if less than 1023, you can have as many columns as you want.
For number of rows, I don't think there is limitation.
