I have requirement of generate (or Create) new Hierarchy(Say z) Combining existing two Hierarchies ((Say X and Y)for 0COSTCENTER
There is a daily load Process Chain running for updating Hierarchies X and Y from R/3 to BW.
Present Requirement is generate (or create) New Hierarchy (Say Z) from X and Y Hierarchies (for Selective Child Nodes level 3)
Provide some clue to proceed on this. In Case if we have to write Custom Exit ( EXIT_SAPLRSAP_004 -- INCLUDE ZXRSAU04) then, what are Hierarchy tables, I have to use.
Also what are Cost center related function modules in BW side
Thanks in Advance,
