• What is the cause and solution for SAP error message QS178 - You cannot use entries from catalogs 1 and 3 ?

  The SAP error message QS178, which states "You cannot use entries from catalogs 1 and 3," typically occurs in the context of Quality Management (QM) when dealing with inspection plans or catalogs. This error indicates that there is a conflict between the catalog entries being used in the inspection plan or the quality inspection process.
  Cause:
  The error arises when there is an attempt to use entries from two different catalogs that are not compatible with each other. In SAP QM, catalogs are used to define inspection characteristics, and each catalog can have specific entries that may not be allowed to be used together. For example, Catalog 1 might be for physical characteristics, while Catalog 3 might be for chemical characteristics, and the system does not allow mixing entries from these catalogs in a single inspection plan.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Inspection Plan: Check the inspection plan or the quality inspection process where the error occurred. Identify which entries are being pulled from catalogs 1 and 3.
  
  
  Check Catalog Compatibility: Verify the compatibility of the entries from the catalogs. Ensure that you are not mixing entries from catalogs that are not allowed to be used together.
  
  
  Modify Inspection Characteristics: If you need to use characteristics from both catalogs, consider creating separate inspection plans for each catalog or modifying the existing plan to use only compatible entries.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific details on the catalogs you are using. This can provide insights into which entries are compatible.
  
  
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for further assistance.
