Smart SAP Assistant

• What is the cause and solution for SAP error message WGDS_PROCESS090 - Quan_unit_iso is initial ?

  The SAP error message WGDS_PROCESS090: Quan_unit_iso is initial typically occurs in the context of Warehouse Management (WM) or Extended Warehouse Management (EWM) processes, especially during goods movements or posting changes where quantity units are involved.
  
  Cause
  
  The field QUAN_UNIT_ISO (ISO code for the quantity unit) is initial (empty or not filled) when the system expects it to be populated.
  This usually happens because the unit of measure (UoM) for the quantity being processed is missing or not correctly determined.
  The system requires the ISO code of the unit of measure to process the quantity correctly, for example, during transfer postings, goods receipt, or goods issue.
  Possible reasons:
  
  The material master does not have a base unit of measure or it is not maintained properly.
  The unit of measure used in the transaction is not recognized or not mapped correctly.
  Custom code or user-exits/enhancements that manipulate quantity or unit fields might be clearing or not setting this field.
  Data inconsistencies or missing configuration in the unit of measure settings.
  
  
  
  
  Solution
  
  
  Check Material Master:
  
  Verify that the material master (MM02) has a valid base unit of measure maintained.
  Ensure that the unit of measure is consistent and correctly maintained in the material master.
  
  
  
  Check Unit of Measure Configuration:
  
  Go to transaction CUNI (Units of Measure) and verify that the unit of measure used in the transaction has a valid ISO code assigned.
  If the unit of measure is custom or non-standard, assign the correct ISO code.
  
  
  
  Check the Transaction Data:
  
  Review the data being posted in the transaction causing the error.
  Ensure that the quantity unit is correctly entered and recognized by the system.
  
  
  
  Debug or Review Custom Code:
  
  If there are user-exits, BADIs, or custom programs involved in the process, check if the field QUAN_UNIT_ISO is being cleared or not set.
  Adjust the code to ensure this field is populated with the correct ISO unit code.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks or data validation reports to identify any materials or units of measure with missing or incorrect ISO codes.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known issues related to this error message.
  For example, SAP Note 0000000 (replace with actual note number if available) might provide patches or corrections.
