Hello Thumma,

1). When running the transaction, did you checked what are the tables its reading ? Try to run ST05 trace and create an Index for the table which spends most time on it.

2). On the tables that you see in SM50 for the t-code KE30, run Individual statistics in DB20.

3). How is your St02 buffers look like. Did you run SAPPFPAR Check ?

You can run like /usr/sap/<SYSTEMNAME>/SYS/exe/run/sappfpar check pf=/usr/sap/<SYSTMENAME>/SYS/profile/<Profile name> nr=<System number> name=<System name>

Tune the SWAPs as recommended by SAPPFPAR . Refer to below link

Hi,

May be you can consider increasing Dialog WP timeout parameter, additionally check this forum link for similar issue:
