Does anyone experience 2 way linking ( File_data is External data souce of File_app, and File_app is External data souce of File_data ) ?
i was working on an exsiting file, and want to make it a separation model, the problem is this , there's some conditional value list they use which needs some relationships.
also some fields at field level to validate using those value lists.
now it creates the problem that , if i put this relationship in front only which is the File_app, and delete the relationship at the File_data, the field can not valid based on the value list any more,
then my coworker find a way that link the File_app as external data souce to File_data, and using the value list from File_app to valid the field at the back end File_data.
but both of us have no idea about this 2 way linking is good practice or bad in somewhere waiting for us.
Thanks for any advice !
