    HI Aisurya,

    That is right. You cannot have more than one table returning from one gateway request. However you have two options.

    1. Multiple tables which you want to return have parent child relationship? Ex: Sales Order header and Sales order Items? Then you need to use $expand on a query on the parent entity.

    2. You can also use $batch to send multiple requests to the backend, so that you fetch one table for every request. Search in scn for $batch. There are good blogs on it.

    • Hi Aisurya,

      But if each custom FM calls the same Standard FM then you do not achieve anything since you will be calling the standard FM returning all four tables every time. Even with the current standard FM you can achieve my approach. While data source mapping for each of the four entity, you just need to map one of the table and leave other three tables without mapping. But the problem is that for each entity FM call is made and you will not be able to utilize three other tables populated.

      My suggestion was, Instead of suppressing three other tables, see if you can just get one table in your custom FM. In that case you save the processing for populating three other tables every time.
