Data classes during 2004s upgrade & report RSDG_DatCls_Assign

55 Views

BW Experts,

I'm preparing for a 2004s upgrade, and on page 71 of the SAP Netweaver 2004s Business Intelligence ABAP upgrade guide, it states that dataclasses that don't use proper naming conventions will no longer be supported, and to create a new data class and use report RSDB_DADCLS_ASSIGN to move your cubes over to the new data class.

I cannot find good help within SAP for this, and after reading several posts, I still have some questions:

1) Is there an easy way to quickly check my cubes to see what data classes they are assigned to? I can use SE11 and look at the Technical Settings to see the data class individually, but there has to be a better way.

2) Below is a list of the data classes that show up in the table DDart. It appears that only two are Customer data classes, and they seem to match the naming convention (user, user1). From this list it appears I don't have anything to worry about - is this true?

APPL0 STD Master data, transparent tables

APPL1 STD Transaction data, transparent tables

APPL2 STD Organization and customizing

CLUST CPT Phys. cluster table

DDIM STD

DFACT STD

DODS STD

POOL CPT Phys. pooled table

SAUS SYS Exchange tables for upgrades

SDIC SYS ABAP Dictionary Table

SDOCU SYS Documentation

SLDEF SYS Repositoryswitch tablespace 640

SLEXC SYS Repositoryswitch tablespace 640

SLOAD SYS Screen and report loads

SPROT SYS SPOOL and logs

SSDEF SYS Repositoryswitch tablespace 640

SSEXC SYS Repositoryswitch tablespace 640

SSRC SYS Source for screens and reports

TEMP INT Temporary table for converter

USER USR Customer data class

USER1 USR Customer data class

We're currently running BW 3.5 in Oracle/Unix.

As always, any help is greatly appreciated.
