Re: which way is better for creation of sales order from incoming idoc

As per my understanding there are 2 message types that can be used for creation of sales order

one is ORDERS that calls the FM IDOC_INPUT_ORDERS and another one SALESORDER_CREATEFROMDAT2 that calls the FM BAPI_IDOC_INPUT1(for BAPI process code) which internally calls the BAPI_SALESORDER_CREATEDATAFROM2

We are going to receive idoc from a middleware so I would like to understand which can be a better approach with/without custom fields.

1.If there are no custom fields

2.If there are custom fields

Thanks
