  The SAP error message /SAPAPO/MSDP_PB051 indicates that there is a mismatch in the planning areas of the planning books you are trying to work with. This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are attempting to perform operations that require both planning books to have the same planning area.
  Cause:
  The error is caused by one of the following reasons:
  
  Different Planning Areas: The two planning books you are trying to use are based on different planning areas. Each planning book is associated with a specific planning area, and they must be identical for certain operations (like copying data, merging, etc.) to be performed.
  Configuration Issues: There may be a configuration issue where the planning books were not set up correctly or have been modified after their initial setup.
  Data Integrity Issues: There could be inconsistencies in the data or configuration that lead to this error.

  Ensure that both planning books are linked to the same planning area.

  If the planning books are indeed linked to different planning areas, you will need to either:
  
  Change one of the planning books to use the same planning area as the other.
  Create a new planning book that is based on the correct planning area.
  
  
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings for both planning books to ensure they are set up correctly. This includes checking the key figures, characteristics, and other settings that might affect the planning area.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed steps on how to configure planning books and planning areas correctly.
  
  
  
  Testing:
