Value Mapping replication step by step in PI 7.3

Hello Everyone,

Has anyone implemented the value mapping replication in PI 7.3 for mass values with dual stack(having ABAP with Java)?

There is help provided in SAP help as in the below link :

http://help.sap.com/saphelp_nw73/helpdata/en/4a/3626a9d5e92ab1e10000000a42189c/frameset.htm

but its not very clear as to where to call the ABAP program, if table of data is stored on the ABAP stack of PI 7.3, etc.

Also, how it behaves wrt performance for frequent hits to the table  as likely the data table is stored on the ABAP stack of the PI system?

Please let me know if you have already done.

Thanks in advance,

Shaily
