• What is the cause and solution for SAP error message AZ051 - Selection criteria for PLANTS '*' and ' ' only valid with operator '=' ?

  The SAP error message AZ051 indicates that there is an issue with the selection criteria for the "PLANTS" field in a report or transaction. Specifically, the error arises when the selection criteria for the PLANTS field is set to a wildcard ('*') or is left blank ('    '), which is not valid unless the operator is set to '=' (equal).
  Cause:
  
  Invalid Selection Criteria: The error occurs because the system expects a specific plant code or a valid operator for the selection criteria. Using a wildcard or leaving the field blank does not conform to the expected input format.
  Operator Mismatch: The selection operator used for the PLANTS field is not compatible with the input provided. For example, if you are using a wildcard or leaving it blank, the operator should be '='.
  
  Solution:
  
  Specify a Valid Plant Code: Instead of using a wildcard or leaving the field blank, enter a specific plant code that you want to filter by.
  Change the Operator: If you need to select multiple plants, consider using the appropriate operator. For example, if you want to select all plants, you may need to use a different selection method or adjust your query to accommodate the required input format.
  Check Input Fields: Ensure that all required fields are filled out correctly and that the selection criteria are valid for the report or transaction you are executing.
  
  Related Information:
  
  Transaction Codes: This error can occur in various transactions that involve plant selection, such as inventory management, production planning, or material management.
