MDM to R3

Hi,

We have an idoc DEBMDM coming out from MDM to R3. XI would map it to 2 idoc types in R3. First one by default is DEBMAS and for only specific values on field E2KNA1M-KUKLA, the second idoc CREMAS has to be created.

I have created separate message mapping for both these idocs. Should i create separate Interface mapping as well ? How can i mark my condition(for CREMAS) on the directory ? Is there other better way?

Thanks,

Ram.
