Hi ,
1. This issue may due to wrong configuration or enhancement, so first I think you can try to run
t-code: su3 and add user parameter WCF_IGNORE_ENHANCEMT, and set the value as A per note
1311966, and try to retest the behavior by the standard configuraiton without enhancement.
2. If issue still occurs after above step 1, maybe you can check if below note is in your system or not.
