• What is the cause and solution for SAP error message MC775 - Operator & is not allowed in a selection condition. ?

  The SAP error message MC775 ("Operator & is not allowed in a selection condition") typically occurs in the context of SAP's reporting and data selection processes, particularly when using selection conditions in queries or reports. This error indicates that there is an issue with the logical operators being used in the selection criteria.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Invalid Operator: The operator used in the selection condition is not recognized or is not allowed. For example, using & (which is often used for concatenation) instead of valid logical operators like AND, OR, etc.
  Syntax Error: There may be a syntax error in the way the selection condition is written, leading to the system not being able to interpret it correctly.
  Field Compatibility: The fields being compared may not be compatible for the operation being performed.
  
  Solution:
  To resolve the MC775 error, you can take the following steps:
  
  
  Check the Selection Condition:
  
  Review the selection criteria in your report or query. Ensure that you are using valid logical operators. Replace & with AND or OR as appropriate.
  
  
  
  Correct Syntax:

  Field Compatibility:
  
  Verify that the fields you are using in the selection condition are compatible. For instance, if you are comparing a numeric field with a string, it will lead to errors.
  
  
  
  Use of Parentheses:
  
  If you have complex conditions, consider using parentheses to group conditions properly, which can help clarify the logic and avoid errors.
