• What is the cause and solution for SAP error message O3404 - Units of measure for stock quantities differ between tables & and & ?

  The SAP error message O3404 indicates that there is a discrepancy in the units of measure (UoM) for stock quantities between two different tables. This typically occurs during inventory management processes, such as when trying to post goods movements or perform stock transfers. The error suggests that the system has detected that the units of measure for the stock quantities in the two tables being compared do not match, which can lead to inconsistencies in inventory data.
  Cause:
  
  Different Units of Measure: The most common cause is that the same material is being referenced in different units of measure in different tables. For example, one table might have stock quantities in kilograms while another has them in grams.
  Configuration Issues: There may be configuration issues in the material master data, where the base unit of measure is not correctly set or where alternative units of measure are not properly defined.
  Data Inconsistencies: Data inconsistencies can arise from manual entries, incorrect data uploads, or issues during data migration.
  Custom Developments: If there are custom programs or enhancements that manipulate stock data, they may not be handling units of measure correctly.
  
  Solution:
  
  
  Check Material Master Data: Verify the material master data for the affected material. Ensure that the base unit of measure and any alternative units of measure are correctly defined and consistent across all relevant tables.
  
  Transaction Code: MM03 (Display Material)
  
  
  
  Review Stock Data: Use transaction codes like MB52 (List Warehouse Stocks on Hand) or MB5B (Stocks for Posting Date) to review stock quantities and their units of measure in the relevant tables.
  
  
  Consistency Check: Run a consistency check on the stock data. You can use transaction code OMW1 to check for inconsistencies in the stock data.
  
  
  Adjust Data: If discrepancies are found, you may need to adjust the stock quantities or correct the units of measure in the affected tables. This may involve posting adjustments or correcting the material master data.
