For many reasons, we've decided to create an SAP HCM (for PA) wide OData service, similar to SuccessFactors OData.
We were wondering where to start - is HCM BOL/GENIL that's already in place for HR renewal https://help.sap.com/viewer/6b8fd09163834a8aaf684887fc9757b8/2.5.41/en-US/92c0b0771ac649d4b74ab65424e7243c.html the best place to start?
Or should we start somewhere else? Please throw some light
