W8163 - Details

• SAP Error Message:
  W8163 - Object types & and & are not compatible
  
  
  Cause:
  This warning message occurs when an operation involves two objects (such as data objects, variables, or parameters) of incompatible or mismatched object types. The system detects that the types of the two objects involved do not match or cannot be used together in the given context.
  For example, this can happen when you try to assign or compare two variables of different object types, or when you try to perform operations that require compatible types but the types differ.
  
  Explanation:

  The incompatibility means that the system cannot safely or logically process the operation because the types do not align.
