QOUT Scheduler Administration: Improving tRFC/qRFC Performance 

Use

In tRFC and qRFC, an entry is made in database table ARFCRSTATE for each LUW that is about to be processed. Because of the guaranteed transactional security, this entry is deleted two minutes after the successful completion of the LUW in question.

Procedure

Entries can only be deleted if the next LUW is already being processed. We therefore recommend that you set parameter abap/arfcrstate_col_delete to 'X' (in DEFAULT.PFL).

Result

Function module ARFC_DEST_CONFIRM can no longer delete the entries in ARFCRSTATE directly. This task must be performed by a regular scheduled background job (minimum: every two minutes, default: every five minutes) using report RSTRFCEU.

 This table can grow very quickly in both tRFC and qRFC. You are therefore advised not to make the interval between two delete jobs too long. We recommend that you perform this action in at least one production system.
