Cardinality Issue - WD Model (Form) Integration with BAPI

Hi -

We have an issue with our forms editable fields are getting disabled (read only, we can not enter data) even though we have proper properties set.

Our developers are looking into a possible cardinality issue i.e. our form fields are test field and have a cardinality of 0..1, where as our bapi structure is showing a cardinality of 0..n for the corresponding field in bapi.

We had internal table as an export parameter so we though may be because of that we are getting 0..n. However we have changed the internal table to a type of structure and recreated a model mapped all the controller and context nodes back to the new structure and still get 0..n cardinality.

We have already researched on SDN logs and did not find any relevant answers.

Any one have any idea please make our weekend happy 😉 Developers are really working hard on Friday to close on this before they go home.

    Hi Shahid,

    If the context node cardinality is 0...1 or 0...n then you need to first create or bind an element to the node to make the form fields editable to which those nodes are bound to. If it's a model node then you need to instantiate a new model node object and bind it to the node e.g.:

    Bapi_xxx_Input input = new Bapi_xxx_Input();


    Or if it's a value node then you need to instantiate the node element as below:


    Hope this helps.

      it is not a good practice to have structures in import/export parameters. Have it in the tables tab and fill in the only record from your test form fields onto the bapi table. It saves a lot of processing time.
