Here we would like to draw your attention to OOIL transaction code in SAP. As we know it is being used in the SAP PA-OS (Organizational Structure in PA) component which is coming under HR (HCM) PA module (Personnel Management). OOIL is a transaction code used for Integration Cost Allocation in SAP.
It comes under the package for Organization and planning (application) (PP00). When we execute this transaction code, RHCUST01 is the normal standard SAP program that is being executed in background. Transaction code OOIL is included in the SAP component for SAP_HR.
