• What is the cause and solution for SAP error message CI_DRAFTPRD_MESSAGE126 - Unit of measure & not allowed for the current product ?

  The SAP error message CI_DRAFTPRD_MESSAGE126, which states "Unit of measure & not allowed for the current product," typically occurs in the context of product master data management, particularly when dealing with product variants, material master records, or during the creation of purchase orders or sales orders.
  Cause:
  This error usually arises due to one of the following reasons:
  
  
  Incorrect Unit of Measure (UoM): The unit of measure being used for the product is not defined or allowed for that specific product in the system. This can happen if the UoM is not set up in the material master or if it is not compatible with the product's configuration.
  
  
  Product Configuration Issues: If the product is a variant or has specific configurations, the UoM may not be valid for that particular configuration.
  
  
  Master Data Inconsistencies: There may be inconsistencies or missing data in the product master data that prevent the use of the specified UoM.
  
  
  Custom Settings or Restrictions: There may be custom settings or business rules in place that restrict the use of certain units of measure for specific products.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Material Master Data:
  
  Go to the material master record for the product in question (transaction code MM03).
  Verify the units of measure defined for the product. Ensure that the UoM you are trying to use is listed and is appropriate for the product.
  
  
  
  Review Product Configuration:
  
  If the product is a variant, check the configuration settings to ensure that the UoM is valid for that specific variant.
  
  
  
  Update UoM Settings:
  
  If the UoM is not defined, you may need to add it to the material master. This can be done using transaction code MM02 (to change the material master) and adding the required UoM in the appropriate views.
  
  
  
  Consult with Business Rules:
  
  If there are custom business rules or settings that restrict UoM usage, consult with your SAP functional team or business process owner to understand the restrictions and make necessary adjustments.
  
  
  
  Check for Data Consistency:
  
  Ensure that there are no inconsistencies in the master data that could be causing the issue. This may involve running data consistency checks or reports.
  
  
  
  Testing:
  
  After making the necessary changes, test the transaction again to see if the error persists.
