Performance problem in fiori app "Approve Requests"

[zbynek_kabrt3]

Hello,

we have performance problem with fiori application "Approve Requests" (CA_ALL_APV). For some users the application is not able to read selected workitem's detail because it falls down on timeout error. SAP NW Gateway sends request for workitem's data into backend system but the function module /IWWRK/WF_TGW_EXPAND on the backend side is not able to send response until 1 minute. After we increased value of timeout parameter on gateway we are able to  get workitem's detail but this is not permanent solution. Users can not wait 2 minutes for response of backend system.

I found out that problem is caused in method GET_TGW_WORKLIST of class /IWWRK/CL_TGW_WF_USER_INBOX on backend. There is read all workitems assigned to current user included completed workitems. The subsequent filtering this workitems takes too much time. Therefore the problem affects only users who had assigned large number of workitems in the past.

Do you have any experience with this issue? Do you know any relevant SAP note?

Thanks in advance for any advice!

Hi Zbynek,

These 3 items can help performance.

+ Use My Inbox. Approve Requests is old app.

+ Apply performance fix notes in the SAP BASIS (Backend Business Workflow).

+ Archive old workitems
