• What is the cause and solution for SAP error message CM_MDG_BS_MAT_GEN025 - It is not allowed to delete the first row referring to the Base UoM ?

  The SAP error message CM_MDG_BS_MAT_GEN025 indicates that you are trying to delete the first row of a table or list that refers to the Base Unit of Measure (UoM) in the Material Master data. This error typically occurs in the context of Material Data Governance (MDG) when managing material master data.
  Cause:
  The error arises because the Base UoM is a critical attribute in the material master record. The first row in the UoM table is usually designated as the Base UoM, which is essential for various business processes, including inventory management, purchasing, and sales. Deleting this row would compromise the integrity of the material data, as every material must have a defined Base UoM.
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check the UoM Configuration: Ensure that you have a valid Base UoM assigned to the material. You cannot delete the Base UoM; instead, you may need to change it if necessary.
  
  
  Add a New UoM: If you need to change the Base UoM, you should add a new UoM first. Once you have a new UoM in place, you can then change the Base UoM to the new one.
  
  
  Modify Existing UoM: If you need to modify the existing UoM, do so without deleting the first row. You can change the attributes of the UoM instead.
  
  
  Consult Documentation: Refer to SAP documentation or your organization's guidelines on managing material master data to ensure compliance with best practices.
  
  
  Seek Help from SAP Support: If you are unsure about the changes or if the issue persists, consider reaching out to your SAP support team or consulting SAP Notes for further assistance.
