• What is the cause and solution for SAP error message DB664 - The options EQ / NE allow only single values ?

  The SAP error message DB664 indicates that there is an issue with the use of the operators EQ (equal) and NE (not equal) in a database query or selection criteria. This error typically arises when you attempt to use these operators with multiple values, which is not allowed. Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  The error occurs when a query or selection criteria is constructed using the EQ or NE operators with a range of values or a list of multiple values. For example, using field EQ (value1, value2) or field NE (value1, value2) is not valid.
  This can happen in various contexts, such as ABAP programs, selection screens, or database views where the query is not properly structured.
  
  Solution:
  
  
  Use Single Values: Ensure that you are using EQ or NE with a single value. For example:
  
  Instead of field EQ (value1, value2), use:
  
  field EQ value1 
  or use multiple conditions with OR: field EQ value1 OR field EQ value2
  
  
  Instead of field NE (value1, value2), use:
  
  field NE value1 
  or use multiple conditions with AND: field NE value1 AND field NE value2
  
  
  
  
  
  Use IN Operator: If you need to check against multiple values, consider using the IN operator instead:
  
  For example, instead of using EQ or NE, you can write:
  
  field IN (value1, value2) for checking if the field matches any of the values.
  field NOT IN (value1, value2) for checking if the field does not match any of the values.
  
  
  
  
  
  Review Query Logic: If the error occurs in a complex query, review the logic to ensure that the conditions are correctly structured and that you are not inadvertently trying to use EQ or NE with multiple values.
  
  
  Related Information:
  
  ABAP Programming: If you are working with ABAP, familiarize yourself with the syntax and rules for constructing SELECT statements and conditions.
  Database Views: If the error arises from a database view, check the definition of the view to ensure that the conditions are correctly specified.
  SAP Documentation: Refer to SAP Help documentation for more details on SQL syntax and operators.
  
  By following these guidelines, you should be able to resolve the DB664 error and construct valid queries in SAP.
