A question of approach...

Hi all,

We have an interface between an external system and an internal SAP system. The information contained in the file that we receive from the external system is incomplete, but is of common interests. We believe that we can easily "fill in the blanks" by calling BAPIs on our ISU system.

Our question: considering we plan on using XI 3.0, which approach is best?

1. On XI: pulling the information from ISU (via RFC) at runtime (and maybe create a lot of traffic, and performance problem?);

2. On ISU: pushing the information to XI? (and duplicate some tables? maintenance problems?)

Note: I've tried to summarize the interface as much as I could, but if needed, I can give you all the details.

    Hi Nathalie,

    In XI 3.0 with BPM you will be able to perform this kind of synchronous lookup on the fly. But as you mention this will create some overhead.

    In my opinion it does not help very much to replicate the data locally, as you will have to perform the lookup via RFC anyway. You will save some network traffic but it may not be worth the effort.

    In XI 3.0 the concept of value mapping will be enhanced. But I do not know if it will be possible to refresh the contents of a value mapping table automatically, based on an RFC. I will keep you posted.
