  The SAP error message WRF_WLAY159 indicates that the unit of measure (UoM) specified for a material is not valid in the context of the operation you are trying to perform. This error typically occurs in the SAP system when dealing with materials in the context of sales, inventory management, or logistics.
  Cause:
  
  Invalid Unit of Measure: The unit of measure you are trying to use for the material is not defined in the material master data.
  Incorrect Configuration: The unit of measure may not be configured correctly in the system, or it may not be assigned to the material in the relevant views (e.g., Sales, Purchasing, or Plant data).
  Unit of Measure Conversion: There may be issues with the conversion factors between different units of measure if the system expects a specific UoM.
  Material Status: The material might be in a status that does not allow certain operations, which could include the use of specific units of measure.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the relevant views (Basic Data, Sales, Purchasing, etc.) to ensure that the unit of measure is correctly defined.

  Define or Update UoM:

  Ensure that the UoM is valid for the material type and is properly configured in the system.
  
  
  
  Check UoM Conversion:

  Review Material Status:
  
  Check if the material is blocked or has any restrictions that might prevent the use of certain units of measure.
