RFC Call to ECC system

Question

Hello Friends,
Need input from you with regards to the Problem/Solution mentioned below:
Our requirement is that during the load of FI data from our Centralised ECC System, we want to retrieve the Billing document details from a new ECC System. Since we need only the Billing Doument and Count of Item data from this new ECC System we dont want to proceed with the regular way of Establising Source System connection and creating new Datasources etc.
The Solution we have thought is to set up a RFC Connection and Execute a Function Module during the Routine execution in BW. Thie Function Module will be executd in the new ECC system and will retrieve the required Billing details.
If you have faced similar situation and implemented any other solution then please let me know.
Any help is appreciated!

Nitin S.

Hi Nitin ,
The solution sounds good . The only problem which i found in this is suppose for any reason your RFC does not work for a day or two . Then the FI data will be loaded without billing information . It will be a difficult task to reload the FI data again for the missing Billing Information .
I assume that your FI postings are happening in Centralized ECC while correspong Billing Docs are in New ECC . So the two ECCs have a RFC conncection between them :
Following approaches can be taken :
1) As per your solution you are going to call the RFC in BI . Instead of doing it in BI , do the same thing in the enahncement of the FI Datasource i.e make a call from centralized ECC to your new ECC . This will affect the extraction performance , but your loading performance will be improved .
2) Is there a possibility that you can flow your billing documents to your centralized ECC and then do a datasource enhacement of the FI datasource .
Hope the above reply was helpful.
