• What is the cause and solution for SAP error message ACI_API003 - Type of property does not match type of GET_...() method ?

  The SAP error message ACI_API003 indicates that there is a type mismatch between a property and the corresponding GET_...() method in an ABAP class or interface. This typically occurs when the data type of a property defined in the class does not match the data type returned by the getter method.
  Cause
  The error can arise from several scenarios:
  
  Data Type Mismatch: The property is defined with a specific data type, but the GET_...() method returns a different data type.
  Inconsistent Definitions: If the property is defined as a certain type (e.g., STRING), but the getter method is returning a different type (e.g., CHAR or a complex type), this will trigger the error.
  Changes in Class Definition: If the class or interface was modified (e.g., changing the type of a property or the return type of the getter method) without updating the corresponding method or property, this can lead to inconsistencies.
  
  Solution
  To resolve the ACI_API003 error, follow these steps:
  
  
  Check Property Definition: Review the property definition in the class or interface. Ensure that the data type is correctly defined.
  
  
  Check Getter Method: Examine the GET_...() method associated with the property. Ensure that the return type of the method matches the data type of the property.
  
  
  Update Definitions: If there is a mismatch, update either the property definition or the getter method to ensure they are consistent. For example:
  
  If the property is defined as STRING, ensure the getter method returns a STRING.
  If the property is defined as a complex type, ensure the getter method returns the same complex type.
  
  
  
  Recompile the Class: After making the necessary changes, recompile the class or interface to ensure that the changes take effect.
  
  
  Test the Changes: Execute the relevant code to verify that the error has been resolved and that the property and getter method are functioning as expected.
