Authorization of Tcodes PT01,PT02 in Production server

Hi Folks,

I have a scenario wherein the client need to generate workschudules at the beginning of ever year using PT01 and make changes using PT02 whenever required.

Those these tcodes are authorized in the respective roles. SAP is not alllowing changes as the clisnt is locked for SPRO access.

Tell me how this is address in general.
