• What is the cause and solution for SAP error message 51013 - Only single values (EQ or =) are allowed. ?

  The SAP error message 51013, which states "Only single values (EQ or =) are allowed," typically occurs when a user attempts to input multiple values in a field that only accepts a single value. This error is common in various SAP transactions and reports where the system expects a specific format for input.
  Cause:
  
  Field Restrictions: The field in question is designed to accept only a single value (e.g., a specific material number, customer ID, etc.), but the user has entered multiple values or a range.
  Incorrect Input Format: The input may be formatted incorrectly, such as using commas or other delimiters that suggest multiple entries.
  Selection Criteria: In selection screens, if a user tries to use operators that imply multiple values (like IN or BETWEEN) in a field that only allows equality checks (EQ or =), this error will occur.
  
  Solution:
  
  Check Input: Review the input in the field that triggered the error. Ensure that only a single value is entered.
  Use Correct Operators: If you need to filter by multiple values, check if there are alternative fields or options available that allow for multiple selections. For example, some selection screens have a "multiple selection" button (often represented by a button with a list icon) that allows you to select multiple values.
  Consult Documentation: Refer to the specific transaction or report documentation to understand the expected input format and constraints for the fields.
  Adjust Selection Criteria: If you are using a selection screen, ensure that you are using the correct criteria for the fields. For example, if you need to filter by a range, look for fields that support that functionality.
