This error typically arises in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where strategies for planning and allocation are defined.
  Cause:
  The error message "LB052 Selection class &1 does not exist. Check strategy type &2 (&3)" can occur due to several reasons:

  Transport Issues: If the configuration was transported from another system, there may have been issues during the transport process that resulted in missing or incomplete data.
