• What is the cause and solution for SAP error message WY067 - Number '0' not defined ?

  SAP Error Message:
  
  WY067 - Number '0' not defined
  
  Cause:
  The error message WY067 typically occurs in SAP Warehouse Management (WM) or Inventory Management (IM) scenarios when the system tries to reference a number (often a warehouse number, storage type, or another key organizational unit) that is set to '0' but this number '0' is not defined or does not exist in the system configuration.
  Common causes include:
  
  A missing or incorrect warehouse number or storage type in the master data or transaction.
  A configuration or master data inconsistency where the system expects a valid number but finds '0'.
  Custom code or user input passing '0' as a key number where it is not allowed.
  Integration issues where data from other modules or external systems is incomplete or incorrect.
  
  
  Solution:
  
  
  Check the Number Being Used:
  
  Identify which number the system is trying to use when the error occurs (e.g., warehouse number, storage type, movement type).
  Verify that this number is correctly maintained in the relevant master data.
  
  
  
  Verify Master Data:
  
  Go to the relevant master data transaction (e.g., LX01 for warehouse number, LS01N for storage type) and check if the number '0' exists or if the expected number is missing.
  If '0' is not a valid number, correct the master data or transaction input to use a valid number.
  
  
  
  Check Configuration:
  
  In SPRO, verify the configuration for warehouse numbers, storage types, and other relevant organizational units.
  Ensure that no configuration step has '0' as a placeholder or default value where it should not be.
  
  
  
  Review Custom Code or User Exits:
  
  If custom developments or user exits are involved, check if any code is setting or passing '0' as a number.
  Correct the code to pass valid numbers.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks or reports to identify any master data inconsistencies.
  Use transaction codes like LX02 (Display Warehouse Number) or LS24 (Display Storage Bin) to verify data.
  
  
  
  Correct Transaction Input:
  
  When performing transactions, ensure that the correct numbers are entered and not '0'.
