CATS(Integration of Primavera -P6 with SAP CATS)

Hi,

Presently i am working on integration on Oracle Primavera with SAP CATS(Cross Application Time Sheet).

AS IS Scenario:

Users fill up entries in ESS and it goes to CATSDB(Database).From CATSDB,concerned information hits to target areas in CO(CATSCO),HR (PTEX2000-HR)and MM(CATSMM).

TO BE Scenario:

Requirement is that keeping link of CATSDB to HR(PTEX2000) and CATSDB to MM(CATSMM) as it is .But to break link of CATSDB to CO(CATSCO).It is required to bypass CATSDB to hit target area of CO.It is required that pass entries in CO from P6(Primavera) i.e.from P6 to CO.

Suggest me how it is to be done?
