Performance improvement for ALE/IDOC night batch job

[Former Member]

Dear experts

We are using SAP R\3 4.5b version.We have scheduled 3 periodic(daily) batch job to create 3k , 5k and 8k ZDMPLC (custom message type) idocs.ZDMPLC idocs picks data from ZDMCHWPLC table which contain about 534,578 entries .Jobs are scheduled at 2 hours interval from one another

3k job took 5 hrs,5k took 16 hrs and 8k took 10 hrs to complete which is very slow.

Can you please suggest some ways to improve this?

Many Thanks

Hi anubin,

whats exactly slow?

RBDMIDOC or RSEOUT00?

Try to trace the running job in ST01 / ST05 / SE30.

In ST05, try to find expensive SQL Statements. In SE30, find slow ABAP Coding and the part, where you loose your time (in ABAP or SQL).

Run the job more often?! Not only 3 times a day to create the communication IDOCs.

Schedule the RSEOUT00 for the Idocstype only 3 times a day, if you are limited to sent them only 3 times a day.

Kind regards

be careful as well of the size of the IDOC tables and indexes quality . Run archiving process on IDOC object to ensure the best performance .

Hi,

Your Idoc is specific, your table is specific and your programs are specific: You need to ask your abapers, we can't know what they have done....

Try to take an SQL trace, it may help you to find out if your abapers did a good job...
