ByD Cost centre reporting restrictions for line managers

Experts,

The company uses multiple cost centres and they wish to restrict access to line managers to view only their own costs by running a report line “Cost Centre – line items”. However, the access context is “1007 - Company” (for both data source and MMA - Cost Management WoC) and the restrictions don’t seem to apply to specific org units (cost centres). Is this a limitation in ByD, or maybe there is a report specifically created with the right access context for this?

Any workarounds that creative minds out there can think of?

Best,

Sebastian
