• What is the cause and solution for SAP error message UAMO093 - Cost estimate cannot be performed due to inconsistency ?

  The SAP error message UAMO093, which states "Cost estimate cannot be performed due to inconsistency," typically arises during the cost estimation process in SAP, particularly in the context of Product Costing. This error indicates that there are inconsistencies in the data that prevent the system from successfully executing the cost estimate.
  Causes of UAMO093
  
  
  Master Data Inconsistencies: There may be issues with the master data related to materials, BOMs (Bill of Materials), routing, or cost components. For example, missing or incorrect data in the material master or BOM can lead to this error.
  
  
  Costing Variant Issues: The costing variant used for the cost estimate may not be configured correctly or may be missing necessary settings.
  
  
  Incomplete or Incorrect BOM/Routing: If the BOM or routing is incomplete or has errors, the system may not be able to calculate the costs accurately.
  
  
  Missing Costing Data: If the necessary costing data (like prices, overhead rates, etc.) is not maintained or is inconsistent, it can lead to this error.
  
  
  Versioning Issues: If there are multiple versions of the BOM or routing, and the system is trying to use an outdated or incorrect version, it may cause inconsistencies.
  
  
  Solutions to UAMO093
  
  
  Check Master Data: Review the material master, BOM, and routing for the material in question. Ensure that all necessary data is complete and correct.
  
  
  Validate Costing Variant: Check the configuration of the costing variant being used. Ensure that all required settings are in place and that it is appropriate for the type of cost estimate being performed.
  
  
  Review BOM and Routing: Ensure that the BOM and routing are complete and accurate. Check for any missing components or operations that could lead to inconsistencies.
  
  
  Maintain Costing Data: Ensure that all necessary costing data, such as prices and overhead rates, are maintained and up to date.
  
  
  Use the Costing Run: If applicable, consider using a costing run instead of a single cost estimate, as this can sometimes help in identifying and resolving inconsistencies.
  
  
  Check for Version Conflicts: If there are multiple versions of the BOM or routing, ensure that the correct version is being used for the cost estimate.
