This reply is bit late but to help others who may be running into same issue.. here is my reply -
There are no MASS EDITING features available within SAP standard tool-sets.
The custom program development for each and every editing requirement (for each IDoc type/ Message Type / Segment/ Field) will be very time consuming and expensive. This will require maintenance of these programs as well.
So there is a completely flexible, highly user-friendly, module (SD/FI/MM) independent, IDoc Type and Message Type independent (These are configurable .. so no hard-coding), and middle ware independent custom SAP product out there. It is called Error Message Manager (EMM).
EMM brings utmost innovations to IDOC MANAGEMENT are as a whole. It provides Single Editing, IDoc error Analysis, Monitoring, Mass Editing, Mass Status change, Mass delete, and a number of other user friendly features.
