Problem running Change Log on Z table
I have a custom table with 2 key fields, ~5000 records, containing data that has changed often. In the Technical Settings for the table, Log Data Changes is checked and buffering is off. I need to be able to see changes to the data. I run SCU3 on it for a 10 day period, and it times out. So I run it again in background. Basis flags the job for performance problems stating the problems are because the underlying table DBTABPRT is too big for SCU3 to run efficiently.
Are there changes I can make to the table definition so I can use SCU3 to view changes? Or can someone suggest a solution?
What I am telling you is not a bible text but a way I would pursue solving your issue:
1. take a look at the number of records in DBTABPRT. Open the table using SE11 or SE16 and click the Number of Entries Icon.
2. In SE11 go to Technical Settings and take a look at the Size category. When the number of records exceeds your size category, then adjust it. And run SCU3 again.
Otherwise or when it times out:
Cleanup the table. I am pretty certain SAP provides a program doing this. May this one helps you: RPLDAP_CLEAN_UP_LOG_TABLES.
When not, I would simply create a program and wipe out, let me say, all records older than e.g. 50 days using the SQL DELETE statement. There shouldn't be any problems regarding table-correlations/dependencies. DBTABPRT is pretty much a stand alone table.
