You can define project subcontractors on the C.10.22 Project Subcontractors screen.
To define a project subcontractor, select a company from the LOV in the Company field. All companies defined on the A.10.23 Companies screen and with the company type SUBCONTRACTOR assigned are available for selection.
If the project default ZC_PROJSUB is set to Y, only the subcontractors defined on C.10.22 can be selected in the Site module as a company, for example, on the C.10.02 Warehouses and C.20.21 MIR by Reservation screens.
If the project default ZC_PROJSUB is set to N, all companies defined on A.10.23 and with the company type SUBCONTRACTOR assigned are available for selection.
