• What is the cause and solution for SAP error message CX_MSR_TRC128 - Materials &1 and &2 must have same base unit of measure ?

  The SAP error message CX_MSR_TRC128 indicates that there is a mismatch in the base unit of measure for two materials involved in a transaction or process. This error typically occurs in scenarios such as inventory management, material movements, or when trying to create or process documents that involve multiple materials.
  Cause:
  The error arises when:
  
  Two materials (e.g., Material &1 and Material &2) are being compared or processed together, but they have different base units of measure defined in their material master records.
  For example, if Material A is measured in kilograms (kg) and Material B is measured in liters (L), the system will not allow operations that require them to be treated as equivalent.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Material Master Records:
  
  Go to the material master records for both materials (using transaction code MM03).
  Verify the base unit of measure for each material. You can find this in the Basic Data view.
  
  
  
  Align Base Units of Measure:
  
  If the materials are intended to be used together, consider changing the base unit of measure for one of the materials to match the other. This can be done using transaction code MM02 (Change Material).
  Note that changing the base unit of measure may have implications on existing stock and transactions, so ensure that this change is appropriate for your business processes.
  
  
  
  Review Transaction Logic:
  
  If the materials are not meant to be compared or processed together, review the logic of the transaction or process that is causing the error. Ensure that the correct materials are being used.
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of changing the base unit of measure, consult your organization's SAP documentation or reach out to your SAP support team for guidance.
  
  
  
  Testing:
  
  After making changes, perform a test transaction to ensure that the error is resolved and that the materials can be processed as intended.
  
  
  
  Related Information:
  
  Base Unit of Measure: This is the unit in which the material is primarily measured and managed in the system. It is crucial for inventory management and reporting.
  Material Master: The material master record contains all the information related to a material, including its base unit of measure, purchasing data, sales data, and more.
  Transaction Codes:
  
  MM03: Display Material Master
  MM02: Change Material Master
  MM01: Create Material Master
  
  
  
  By following these steps, you should be able to resolve the CX_MSR_TRC128 error and ensure that your materials are correctly configured for the intended operations.
