I've performed the following steps in order to call a ABAP web service in an ECC system:
1: generate WS from function module
2: create provider system for the backend system (destination ping = OK)
3: publish WS to Service Registry using the backend system as physical system
4: test the published service in the WSnavigator. I get prompted to log on to the backend system (as expected) and the service works. There a no obligatory parameters.
5: consume WS in BPM process. Select from the SR. The service definition is shown, but I cannot select a endpoint reference (lower part of the screen)!?
6: create automated activity and assign service to the created Service Group
7: Assign Service Group to Provider system in Business scenario communication
When I test this scenario I get a "unauthorised" error which indicates a error on the endpoint. I also believe the problem is caused by the endpoint. On another system I had this scenario running, but for some reason after a re-installation (trial version expired), it doesn't works anymore.
I have found several posts on this issue, but haven't found the solution...
Hopefully somebody can point me in the right direction. Please let me know if I can send the screenshots for more details.
Thanks a lot
