Problem: SAP allowing deletion of service line item after SERVICE ENTRY has been made.
Service order has been created 10 months back (31.10.08). In that service order, there were few line items. Delivery date for those items was 31.12.08.
SERVICE ENTRY was made for a particular line item on 16.12.08.
Based on the actual services at site, delivery dates for all line items were extended up to 02.03.09.
Based on actual completion delivery dates of all line items were changed from 31.12.08 to 2.03.09, but SAP allowed to change delivery date of a particular line item even SERVICE ENTRY was already made on 16.12.08.
And SAP also allows deleting service line item even after service entry has been made.
