• What is the cause and solution for SAP error message WRF_APC502 - Generic material does not correspond to purchasing list item ?

  SAP Error Message:
  
  WRF_APC502: Generic material does not correspond to purchasing list item
  
  Cause:
  This error occurs when there is a mismatch between the generic material assigned and the purchasing list item in the SAP system. Specifically, the generic material specified in the purchasing list does not match or correspond to the generic material defined in the material master or the purchasing info record.
  In SAP, a generic material is used in purchasing lists to represent a group of materials that can be procured under the same conditions. If the generic material assigned to a purchasing list item is inconsistent or incorrect, the system throws this error.
  Typical scenarios causing this error include:
  
  The generic material assigned to the purchasing list item is different from the generic material assigned to the material master or info record.
  The purchasing list item is linked to a material that does not have the expected generic material.
  Data inconsistency or incorrect master data maintenance in the purchasing list or material master.
  
  
  Solution:
  To resolve the error, follow these steps:
  
  
  Check the Generic Material in the Purchasing List:
  
  Go to transaction ME01 (Maintain Purchasing List).
  Display the purchasing list and check the generic material assigned to the relevant purchasing list item.
  
  
  
  Check the Generic Material in the Material Master:
  
  Use transaction MM03 to display the material master.
  Check the generic material field (usually in the purchasing or sales views).
  
  
  
  Verify the Purchasing Info Record:
  
  Use transaction ME13 to display the purchasing info record.
  Check if the generic material assigned here matches the purchasing list and material master.
  
  
  
  Correct the Generic Material Assignment:
  
  If there is a mismatch, update the generic material in the purchasing list or material master to ensure consistency.
  If the generic material is incorrect in the purchasing list, correct it via ME01.
  If the material master generic material is incorrect, update it via MM02.
  
  
  
  Check for Customizing or User Exits:
  
  Sometimes, custom logic or user exits might enforce strict checks on generic materials.
  Review any custom code or enhancements related to purchasing lists or generic materials.
  
  
  
  Reprocess the Transaction:
  
  After correcting the data, retry the transaction that caused the error.
