Events are not triggering from SAP to iVend in the Integration monitor.
When the events are not triggering from SAP to iVend then we should always check two things:
1. iVend transaction notification stored procedure (CXS_Ivend_SP_TransactionNotification) call must be there in SAP Transaction Notification store procedure (SBO_SP_TransactionNotification).
2. "Enable Transaction Notification" setting must be enabled in General Settings in SAP:
Path: (iVend Addon should be started) >> SAP >> Administration >> System Initialization >> General Settings >> Service Tab >> Mark checked "Enable Transaction Notification"
If the above two points are not as per the requirement, then it is a BIG issue because It causes data inconsistency between SAP and iVend and it must be avoided.
