Actully we get the Data for Customer Master in the form of IDocs from MDM system via PI. This Customer Master is having Some more Custom Fileds other than Standard. Can any one suggest me the Best method to Handle all the Fileds Together.
For the Above requirement i got the following Feed Back.
if you are using the DEBMAS(message type), DEBMAS06 (idoc type) . then you can create the extenstion for DEBMAS06. and send the custom fields using the extension. and inbound processing function IDOC_INPUT_DEBITOR is not suitable for your requirement. you may have to go with the custom processing function(custom process code) there you can try with bdc or bapi call.
you need more customizing, attaching the idoctype, messagetype(WE82) ,function module, and BD51, we57, WE42, WE20.
Actually I am not intrested to write Custom Function Module, For this do we have any BADI or User Exit to implement. Please give me some pointers.
