Performance during mass change in Application system

Hi All,

Our aim was to send data from application system (ECC) to event management. It was achieved by calling /SAPTRX/EVENT_MGR_COMMUNICATE in user exits in the OTC transactions such as VA01/VA02, VL01N/VL02N etc.

We could run the design successfully in the quality system but it failed in production system specifically for the mass change jobs running in production. It runs into "Time_Out" error failing in the function module /SAPTRX/EVENT_MGR_COMMUNICATE.

Any tips on how to increase the performance would be appreciated.

Thanks,

Deb
