Hi All,
I am new to abap, I have a requirement to get data from external system. For that I have to configure inbound idocs. I have a doubt here. How to define the structure of the segments of idoc. Do we need to give the external system the structure we want or will they give the data structure they are sending ?
Is it mandatory to define parent child relation between segments for data coming from non sap system.if yes. How ?
