Hi,
You need to delete all DTP requests previously loaded to the Open Hub.
First, you will need the Open Hub technical name and the last REQUID
2 ways:
-> Open the DTP and choose 'Last Request'. There will be a 5 or 6 digit ID for the last request.
-> Go to SE11, table RSBKREQUEST and search using the DTP technical name in the DTP field
Once you have the REQUID, go to SE38 and run program RSBK_DEL_DTP_REQ_FROM_OHD.
You will have to enter the technical name of the open hub, and the last request ID.
You can choose to do a test run first, and the system will retrieve all the previous request IDs.
Execute the program.
To check that it worked, you can try to reopen the DTP and select 'Last Request'. The system should not take you to the monitor window for the last request since there are none left.
Now, you should be able to manually delete the DTP from the modelling workbench as well as the Open Hub itself if required.
If the DTP was used in a process chain, you should get an error message with the technical name of the process chain. Once you delete this variant from the process chain, the DTP can be deleted.
