The current transmission has no previous transmission
(missing previous number: &V1&).

System Response
Inbound processing terminated in background mode. However,further processing is possible in mode in the foreground.

Procedure
Check that the IDoc is correct.
In the Workflow inbox, insert a correct previous number in the IDocfield TRMOLD (Segment: E1EDK40). Make sure that thenumber exists in the table TRNSM (Field: TRMNO_EXT,external transmission number) for the following parameters:
- PartnerNo., PartType, PartRole : &V2&
- Log.Message, MessVar, MessFct : &V3&
- Direction, Test : &V4&
Start inbound processing again (in the background).
Alternatively, you can process the IDoc, unchanged, in mode in theforeground (online).
If you do not want inbound processing to terminate as a result of theexternal transmission number consistency check, set automaticprocessing allowed in Customizing.
