After recent upgrade our standalone moved to Integrated ITS and the issue is that the custom Internet service on execution are not having the custom buttons available in it .
Instead only EXIT and HELP.
We coded in flow logic pf the screen to get the okcode from screen .But now nothing is working.
Please provide inputs ,
You need to migrate the flow logic services. Please see the SAP documentation:
