• What is the cause and solution for SAP error message OIUCM156 - ERROR: DATA NOT SAVED. "Round CA" must be >= "Factor" per UOM. ?

  The SAP error message OIUCM156 indicates that there is an issue with the unit of measure (UOM) configuration in the context of a round-off value and a conversion factor. Specifically, the error states that the "Round CA" (Round Conversion Amount) must be greater than or equal to the "Factor" per the unit of measure.
  Cause:
  This error typically arises in scenarios where you are trying to save data related to materials, products, or transactions that involve unit conversions. The underlying cause is that the rounding configuration for the unit of measure is not set correctly in relation to the conversion factor. 
  For example, if you have a conversion factor of 2.5, the rounding amount must be at least 2.5 or higher. If it is set to a lower value, the system will throw this error to prevent inconsistencies in data.
  Solution:
  To resolve this error, you need to check and adjust the unit of measure settings in the SAP system. Here are the steps you can follow:
  
  
  Access the UOM Configuration:
  
  Go to the transaction code CUNI (Unit of Measure Conversion) or OMN1 (for maintaining UOM in the material master).
  
  
  
  Check the UOM Settings:
  
  Look for the specific unit of measure that is causing the error.
  Verify the "Round CA" value and the "Factor" value.
  
  
  
  Adjust the Values:
  
  If the "Round CA" is less than the "Factor," increase the "Round CA" to be equal to or greater than the "Factor."
  Save the changes.
  
  
  
  Test the Changes:
  
  After making the adjustments, try to save the data again to see if the error persists.

  Unit of Measure (UOM): UOM is a standard way to measure quantities in SAP. Each material can have multiple UOMs, and conversions between them must be defined correctly.
  Conversion Factor: This is the value that defines how one unit of measure relates to another. For example, if 1 liter equals 1000 milliliters, the conversion factor is 1000.
  Rounding: Rounding is important in financial and inventory calculations to ensure accuracy and consistency in reporting.
  
  If you continue to experience issues after making these adjustments, it may be helpful to consult with your SAP support team or refer to SAP documentation for further troubleshooting steps.
