Can I restrict on Personnel Subarea in SAP HCM?
The standard PA authorisations P_ORGIN and P_ORGINCON do not have Personnel Subarea restrictions available unfortunately. The only standard options within these objects are Personnel Area, Employee Group and Employee Subgroup.
It would be possible to add an additional restriction using the Organisational Key field which allows you to essentially define a customised field restriction within the P_ORGIN or P_ORGINCON object. However, our advice is to try and work around the requirement as Org Key restrictions can get very complex and are difficult to maintain as a result.
