• What is the cause and solution for SAP error message CK174 - Selected variants have different quantity structure control ?

  The SAP error message CK174, which states "Selected variants have different quantity structure control," typically occurs in the context of product costing or when working with material variants in SAP. This error indicates that the selected variants of a material have inconsistent quantity structure controls, which prevents the system from processing them together.

  Align Master Data: Make sure that the material master data for the selected variants is consistent. This includes checking the BOM, routing, and any other relevant data.
  Select Compatible Variants: If the variants cannot be aligned, consider selecting only those variants that share the same quantity structure control for your costing or processing task.
  Review Configuration: If you have access to configuration settings, check the configuration for the material types and ensure that they are set up correctly to avoid such discrepancies.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling material variants and quantity structure controls.
