I modified a custom function module of a standard task method to export a concatenation of po items by adding an export parameter and the logic. The function works ok as tested. When I try to do the method binding I don't see the element in the method container, yet I do see the other elements which are the other function parameters. Even though I select the yes button when prompted to transfer missing elements from the object method, the missing element never shows up in the method container. I also tried the enter missing export parameter and generate automatic binding options but nothing works. Everything is activated. Please advise.
