  Define Links: Go to the configuration settings in SAP APO and ensure that you define at least one link between the restriction and the group. This can typically be done in the planning book or data view settings.
  Check Configuration: Review the configuration of both the restriction and the group to ensure they are set up correctly. Make sure that the restriction is applicable to the group you are working with.
  Use Transaction Codes: You may need to use specific transaction codes (like /SAPAPO/SDP94 for planning books) to access the relevant settings and make the necessary adjustments.
  Consult Documentation: Refer to SAP documentation or help resources for detailed steps on how to create links between restrictions and groups.
