Creating Idoc and sending it to its own...

Question

Hello All,
The functional design specified that an inbound function module needs to be created to process a custom IDOC, let's say ZMMDLRTL, and using the data from the segments from this basic type ZMMDLRTL, I need to create another IDOC of basic type PORDCR101 to create a PO. This PO IDOC would then have to be posted to the same system where the inbound function module that would process the ZMMDLRTL IDOC. So this is just like creating an IDOC and sending it to yourself right?
I used the function module MASTER_IDOC_DISTRIBUTE to create the PORDCR101 Idoc and sends it to itself. But now I am getting an error status 20, which is "Receive of IDOC is its own logical system". I just need some inputs on this.
Thanks,
Kristine

Hi!
In two words - to avoid this error you have to send PORDCR101 to another logical system pointing to the same client and make corresponding settings in distribution model (as you use MASTER_IDOC_DISTRIBUTE).
Proceed as follows:
1. Create a "dummy" logical system name, say LOGSYSD. This dummy logical system will serve as the receiver system in the distribution model.
2. Using SM59 create RFC-destination LOGSYSD for the dummy logical system. The RFC-destination addresses the same client.
3. Create a distribution view in BD64 with your "real" logical system for client as the sender and LOGSYSD as the receiver for your message type.
4. Generate partner profiles for distribution model using BD82.
5. Using WE20 create inbound parameters for your message type for <b>"real"</b> logical system.
Hope it helps.

Maxim.
