I'm trying to retrieve templates in Dispute Management (TCODE: UDM_DISPUTE).
The first time, it doesn't retrieve them because the document is still initial and it has to create a connection. Somewhere along the line, it gets the ID of the template, however another ID is getting cached somewhere and it is the wrong value. I can't find out how to clear or disable it. Any ideas?
The templates are stored in transaction SRMREGEDITC --> S_AREA_CMG --> SCMG_SP_DOCUMENT_TEMP
I've had the same issue some time ago. Make sure your template profile is specific for your element type (UDM_SPS_DOCUMENT_TEMP). If there is some sort of cross-over, you might create document from a template that is from a different type and this can cause errors.
Hope this helps.
