Service Request - Service Confirmation as Follow-Up not possible
we have a Service Request (transaction type ZSE1). From this service request I would like to create a follow-up. This should be a Service Confirmation (transaction type ZSEC). Unfortunately I am not able to select this transaction type from the follow-up-menu in the Web Client UI. The copy control for transaction types has an entry for ZSE1 as source to ZSEC as target.
What might be the reason?
I know that there are a lot of reasons why the desired follow up transaction is not available but where can I start to investigate?
Is there a good guide for root cause analysis or is there any possibility to simulate everything?
Thanks for any hints in advance,
