• What is the cause and solution for SAP error message W_CB426 - List and material exclude one another ?

  SAP Error Message:
  W_CB426 - List and material exclude one another
  
  
  Cause:
  This warning message occurs in SAP when you try to assign or use a material and a material list simultaneously in a context where they are mutually exclusive. In other words, the system does not allow both a material and a material list to be specified together because they represent alternative ways to define the scope of materials.
  For example, in processes like batch determination, availability check, or pricing, you can either specify a single material or a list of materials (material list), but not both at the same time. The system detects this conflict and issues the warning.
  
  Explanation:
  
  Material: A single material master record.
  Material List: A predefined list of materials grouped together for processing convenience.
  
  The system expects either one or the other, but not both, because they serve the same purpose of defining materials for the process.
