  Data Entry Errors: Manual entries in the planning books or master data might have been incorrectly inputted, leading to a sign mismatch.
  
  Solution:
  
  
  Check Resource and Pegging Quantities:

  Review Master Data:
  
  Check the master data for the resources and products involved. Ensure that the settings for capacity, production versions, and other relevant data are correct.

  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on the configuration of resources and pegging in APO.
  
  
  
  Testing:
