How To Fix M3004 - The alternative units of measure are inconsistent

SAP Error Message - Details

• Message type: E = Error

• Message class: M3 - Material Master

• Message number: 004

• Message text: The alternative units of measure are inconsistent

What causes this issue?

The conversion factors you have entered for the alternative units of
measure
either do not correspond to the values in the units of measurement
table (example 1)
or are inconsistent (example 2)

System Response

The system has checked the values for consistency.
&BEISPIEL& 1
You choose g as the base unit of measure and kg as the alternative unit
of measure.
The table definition is: 1,000 g = 1 kg
You enter: 900 g = 1 kg
Since the table defines 1000 g as 1 kg, the system overwrites your
entry of 900 with 1,000.
&BEISPIEL& 2
You choose PC as the base unit of measure, kg as the first alternative
unit, and g as the second alternative unit.
The table definition is: 1 kg = 1,000 g
You enter: 2 PC = 1 kg and 2 PC = 900 g
The table and the first entry define that 2 PC = 1,000 g. The system
overwrites your second entry of 900 with 1,000.

• What is the cause and solution for SAP error message M3004 - The alternative units of measure are inconsistent ?

  The SAP error message M3004, which states "The alternative units of measure are inconsistent," typically occurs in the context of materials management and inventory management within SAP. This error indicates that there is a mismatch or inconsistency in the unit of measure (UoM) settings for a material.
  Cause:
  
  
  Inconsistent Unit of Measure Settings: The primary cause of this error is that the alternative units of measure defined for a material do not align correctly with the base unit of measure. This can happen if:
  
  The conversion factors between the base unit and alternative units are not defined correctly.
  The alternative units of measure are not maintained in the material master data.
  There are discrepancies in the unit of measure settings across different views (e.g., purchasing, sales, and inventory).
  
  
  
  Missing or Incorrect Conversion Factors: If the conversion factors between the base unit and alternative units are missing or incorrectly defined, SAP will throw this error.
  
  
  Material Master Data Issues: If the material master data is incomplete or has been incorrectly modified, it can lead to inconsistencies in the unit of measure.
  
  
  Solution:
  To resolve the M3004 error, you can follow these steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the "Basic Data" and "Purchasing" views for the unit of measure settings.
  Ensure that the base unit of measure and alternative units of measure are correctly defined.
  
  
  
  Verify Conversion Factors:
  
  In the material master, check the conversion factors for the alternative units of measure.
  Ensure that the conversion factors are correctly defined and that they make sense (e.g., 1 box = 10 pieces).
  
  
  
  Maintain Alternative Units of Measure:
  
  If alternative units of measure are not maintained, you can add them using transaction code MM02 (Change Material).
  Navigate to the "Units of Measure" view and add or correct the alternative units of measure.
  
  
  
  Consistency Check:
  
  After making changes, perform a consistency check to ensure that all units of measure are aligned and that there are no further inconsistencies.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct settings, refer to SAP documentation or consult with your SAP support team for guidance on unit of measure configurations.

  Unit of Measure Configuration: Understanding how units of measure are configured in SAP is crucial. This includes knowing how to set up base units, alternative units, and conversion factors.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to the M3004 error or provide additional guidance on unit of measure configurations.
  
  
  By following these steps, you should be able to identify and resolve the cause of the M3004 error in SAP.
