Updating "Z" Tables from different Systems.
We have Two Sap systems, CRM and R/3. I have some "Z" tables on R/3 that sometimes I need on CRM system. To retrieve these data, CRM uses some RFC functions.
My demand is to copy the RFC functions from the R/3 to the CRM system to increase the Performance of the CRM.
The problem is that the "Z" Tables are maintained on the R/3 system, via SM30.
How can I keep the Data from both systems equal? I want that every time a modification is made on the R/3 System, the data is sent to CRM system.
What is the Best way to do it? Someone told me to use "Change Document" Tcode SCDO, but I never used it...
Thanks & Regards!
