How To Fix LB260 - The proportion/product units &1 and &2 are part of dimension &3

SAP Error Message - Details

• Message type: E = Error

• Message class: LB - Logistics: Batch - Management

• Message number: 260

• Message text: The proportion/product units &1 and &2 are part of dimension &3

What causes this issue?

For this material, you are trying to define a unit of measure that
belongs to the same dimension as a proportion unit or product unit that
has already been defined.
If a proportion unit or product unit with assignment of dimension has
been defined for a material, you cannot define any other alternative
units of measure of the same dimension for this material.

How to fix this error?

Delete the alternative unit of measure or the proportion/product unit
belonging to dimension &V3& or
Change the proportion/product units belonging to dimension &V3& into
alternative units of measure.
&FURTHER_HINTS&
Note that the conversion factors for proportion/product units cannot be
automatically corrected.

• What is the cause and solution for SAP error message LB260 - The proportion/product units &1 and &2 are part of dimension &3 ?

  The SAP error message LB260 indicates that there is a mismatch or inconsistency in the units of measure (UoM) being used in a particular context, typically related to inventory management or material master data. The message specifies that the proportion or product units (&1 and &2) are part of a specific dimension (&3), which suggests that the system is expecting certain units to be compatible or correctly defined within the specified dimension.
  Cause:
  
  Unit of Measure Configuration: The units of measure for the materials or products involved may not be correctly defined or linked in the system.
  Inconsistent Data: There may be inconsistencies in the data related to the material master, such as incorrect unit conversions or missing entries in the unit of measure tables.
  Dimension Mismatch: The error may arise when trying to perform operations that require specific dimensions (like weight, volume, etc.) and the units being used do not align with the expected dimensions.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record for the affected materials and verify the units of measure defined.
  Ensure that the base unit of measure and alternative units of measure are correctly set up.
  
  
  
  Review Unit of Measure Settings:
  
  Check the configuration of units of measure in the SAP system (transaction code OME1 for defining units of measure).
  Ensure that the conversion factors between different units of measure are correctly defined.
  
  
  
  Validate Proportions and Dimensions:
  
  If the error is related to a specific dimension (like weight or volume), ensure that the units being used are appropriate for that dimension.
  Check if the proportions or ratios being calculated are valid and that the units align with the expected dimensions.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to unit of measure handling and inventory management to ensure compliance with best practices.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the error no longer occurs and that the system behaves as expected.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like MM03 (Display Material), MM02 (Change Material), or OME1 (Define Units of Measure) to access and modify material master data and unit settings.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to this error message.
  User Forums: Consider searching or posting in SAP community forums for additional insights or similar experiences from other users.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant who can provide deeper insights into the specific configuration of your SAP environment.
