• What is the cause and solution for SAP error message FRMLDLG404 - Lot size unit must not be different from the target input quantity unit ?

  The SAP error message FRMLDLG404 indicates that there is a mismatch between the lot size unit and the target input quantity unit in a process, typically related to production or inventory management. This error often occurs in scenarios involving production orders, material requirements planning (MRP), or when dealing with batch management.
  Cause:
  
  Unit of Measure (UoM) Mismatch: The lot size unit defined for the material does not match the unit of measure of the target input quantity. For example, if the lot size is defined in kilograms but the target input quantity is in grams, this error will occur.
  Configuration Issues: There may be incorrect settings in the material master data or in the production order settings that lead to this mismatch.
  Batch Management: If batch management is enabled, the batch's unit of measure may not align with the expected input quantity unit.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and verify the unit of measure settings. Ensure that the lot size unit and the target input quantity unit are consistent.
  Check the "Basic Data" and "Purchasing" views for the correct units of measure.
  
  
  
  Review Production Order Settings:
  
  If the error occurs during the creation of a production order, check the order's settings (transaction code CO01 or CO02) to ensure that the lot size and input quantities are compatible.
  
  
  
  Adjust Lot Size Configuration:
  
  If necessary, adjust the lot size configuration in the material master or production order to ensure that the units of measure match.
  
  
  
  Batch Management Settings:
  
  If batch management is involved, ensure that the batch's unit of measure is correctly defined and matches the expected input quantity unit.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidance on unit of measure settings and configurations related to your version of SAP.
  
  
  
  Related Information:
  
  Unit of Measure (UoM): In SAP, each material can have multiple units of measure defined, including base unit, purchasing unit, sales unit, etc. Understanding how these units interact is crucial for avoiding errors.
  Batch Management: If your organization uses batch management, ensure that all relevant settings are correctly configured to prevent unit mismatches.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message, as there may be updates or fixes available.
  
  By following these steps, you should be able to resolve the FRMLDLG404 error and ensure that your lot size and target input quantity units are aligned correctly.
