• What is the cause and solution for SAP error message TBA1148 - UoM &1 of underlying DCS cannot be converted to quotation UoM &2 ?

  The SAP error message TBA1148 indicates that there is an issue with the conversion of units of measure (UoM) between the underlying document (such as a delivery or sales order) and the quotation. This typically occurs when the system is unable to convert the UoM from one format to another due to a missing or incorrect configuration.
  Cause:
  
  Missing Conversion Factors: The conversion factors between the two units of measure are not defined in the system.
  Incorrect UoM Settings: The units of measure may not be compatible or correctly set up in the material master or in the relevant configuration settings.
  Inconsistent UoM Usage: The UoM used in the underlying document does not match the UoM expected in the quotation.
  Material Master Issues: The material master data may not have the necessary UoM settings or conversion factors defined.
  
  Solution:
  
  
  Check UoM Configuration:
  
  Go to the material master (transaction code MM03) and check the UoM settings for the relevant material.
  Ensure that the base unit of measure and any alternative units of measure are correctly defined.
  
  
  
  Define Conversion Factors:
  
  If conversion factors are missing, you can define them in the material master under the "Units of Measure" view.
  Use transaction code CUNI to maintain unit of measure conversions if necessary.
  
  
  
  Review Quotation and Underlying Document:
  
  Check the quotation and the underlying document to ensure that the UoM used is consistent and correct.
  If there are discrepancies, adjust the UoM in either the quotation or the underlying document.
  
  
  
  Check Customizing Settings:
  
  Review the customizing settings for units of measure in the SAP system (transaction code SPRO).
  Navigate to the relevant sections under Logistics and ensure that the UoM settings are correctly configured.
  
  
  
  Consult Documentation:
