Cost centers	KSB1 - KSB2
Orders	KOB1 - KOB2 - KOB4
Projects (and networks)	CJI1 - CJI3 - CJI4

Answering previous questions to identify which component we should use to attend this requirement:

WHAT: Add information (receiver WBS of a transfer budget)

WHERE: CJI1 - Budget Line Items Report

So, we could use enhancement component EXIT_SAPLKAEP_004 to attend this business requirements.
