Hello,
I work on SAP Product Support. There are a couple of incidents opened by customers related to high swaps in transaction ST02. My goal with this post is to share some information about causes and solutions related to this topic.
In transaction ST02, a few thousand swaps can be tolerated each day. However, you should consider to enlarge the buffer if you find more than 10000 swaps per day. As you can see in ST02 main screen, there are several types of buffer. The most problematic buffers are listed below:
Additional information about buffers can be found in the following notes:
SAP Note 1918603 - High swaps in transaction ST02
SAP Note 103747: Performance: Parameter recommendations as of Release 4.0
NOTE: It is difficult to say what are the exact values for the parameters of your system. It depends on several factors: number of concurrent users, workload, hardware resources, etc.
Best regards,
Maurício Grisa.
