Raising Event from Change Document - not the main table
I currently have workflow events being triggered from change documement object MELDUNG. The main table in the object is QMEL. I would also like to trigger an event when a change document is written for table IHPA - which is also part of change document object MELDUNG.
In transaction SWED, see the entry for MELDUNG with the Leading table defined as QMEL. I understand I need this for my existing workflow events to continue to work.
How can I raise an event when a MELDUNG change document is written for table IHPA?
