You have created a custom solution and you are trying to extend the split invoice screen, but unable to find an option.
SAP Business ByDesign
Reproducing the Issue
Go to Payables work center.
- Go to Periodic Tasks view.
- Go to Payment Runs sub view.
- Select the Run ID.
- Click on Execution ID.
- Click on View Payment Proposals.
- Go to Adaptation Mode on the Split screen.
- Observe that there is no option to extend the split screen.
The reason you are unable to add extension fields on the Split screen is because currently it is not possible to add extension fields on the Split screen. This is the current expected system behavior.
The partner would have to look at the original document to figure out the value of the extension fields and update it in the related Business Object. But this will need to be evaluated by the partner.
