Message type to inbound function module and inbound process flow.

[former_member813046]

Hi all,

please can someone help me in understanding the need for assigning inbound Function module to the Message Type,

like why do we need to assign the inbound function module to the message type and How is the Function module getting triggered internally when the receiver receives the idoc.

Thank you.

I don't understand what you don't understand.

You receive an idoc, the idoc in the heade contains informations used by SAP to determine witch FM need to run using the input data. it is not logic for you ?

what i couldnt understand is why do we need to assign the inbound function module to logical message type using WE57, during the steps to be followed in inbound process creation

Hello ananthum007

Look at my response How standard tables are updated from standard inbound idoc

Hope it helps you understand the logic from ALE message type, through process code to the function module that actually processes the IDoc.
