Can someone tell me the difference between IDOC message type CREMAS and CREFET I have tried searching for this on few web sites but they are not clear.
Thank you
BD87 - from the "Message Type" field (F4):
CREFET Get vendor data
CREMAS Vendor master data distribution
And I fear it's all I could find. I guess you can find more just by reading the documentation about how to configure iDocs (assign segments, function modules and so).
Maybe you can tell us what is not clear in what you've found in those few sites... it's more probably someone around here can give you further help if you do it.
