  The SAP error message CR172 ("Time (&) not valid as unit of measure") typically occurs when there is an issue with the unit of measure (UoM) being used in a transaction or configuration related to time. This error can arise in various contexts, such as when creating or modifying materials, production orders, or other objects that require a valid unit of measure.
  Cause:
  
  Invalid Unit of Measure: The unit of measure specified is not recognized by the system as a valid time unit. For example, using a non-standard or incorrect abbreviation for time (like "hrs" instead of "H" for hours).
  Configuration Issues: The unit of measure may not be properly configured in the system. This could be due to missing entries in the unit of measure table or incorrect settings in the material master or other relevant configurations.
  Data Entry Errors: There may be a typographical error in the entry of the unit of measure, leading to the system not recognizing it.
  
  Solution:
  
  
  Check Unit of Measure: Verify that the unit of measure being used is valid. Common valid time units in SAP include:
  
  H (Hours)
  M (Minutes)
  S (Seconds)
  Ensure that you are using the correct abbreviation.
  
  
  
  Review Configuration: 
  
  Go to the transaction code CUNI (Unit of Measure Conversion) to check the configuration of units of measure.
  Ensure that the unit of measure for time is defined correctly in the system.
  If necessary, add or modify the unit of measure in the configuration.
  
  
  
  Correct Data Entry: If the error is due to a data entry mistake, correct the entry to use a valid unit of measure.
