Hi,
I'm trying to call a FM, SAP_WAPI_WRITE_CONTAINER. It has a tables parameter so the model's node corresponding to the input (not the output) for the table is mapped to a model node in my controller's context.
I create new elements for this node, add them to a collection and bind the collection to the node. When I then execute this function module, and use the ABAP debugger to see what happens, the tables parameter is empty.
Any commonly used mistakes I might have made?
