Hi Dominic,
Your requirement can be achieved by relevant configuration as given below
1.Check for all the impacted Transaction types and see what is the Task Group(POS inbound processing ->POS Transactions ->Define POS Transaction types)
2.Assign the relevant Task code to all the Task Groups which are assigned to the impacted transaction types(POS inbound Processing ->Tasks ->Assign Tasks to Task Group) with the correct profile type you are using.
If you are using Standard POSDM implementation then you may use the below Taskcodes
1001 - Check for Duplicate Transaction numbers(CT01 in case of Starter Pack POSDM)
1002 - Check for Receipt numbers without Gaps (CT10 in case of Starter Pack POSDM)
Hope it helps
PS: Not sure what is the difference between #001 Sales and #005 Sales though !
Best Regards,
Aram.
