The method ZZGET_NEXT_SUBVIEW_COUNT does not have a RETURNING parameter. It cannot be called in expr

[Catherine3]

When I activate the code, it shows  The method "ZZGET_NEXT_SUBVIEW_COUNT" does not have a RETURNING parameter. It cannot be called in expressions. The coding as following:

    CALL METHOD uo_model_holder->add
      EXPORTING
        im_screen_view = lo_custom_view
        im_position    = uo_model_holder->zzget_next_subview_count( ).

May I know what is wrong with the coding? Thanks in advance.

The problem is exactly what the message says - the method has to implement a returning parameter if it is used in expressions.

May I know what is wrong with the coding? Thanks in advance.

The method "ZZGET_NEXT_SUBVIEW_COUNT" does not have a RETURNING parameter. It cannot be called in expressions

means that you are doing a Functional Method Call (Functional Method Call - ABAP Keyword Documentation (sap.com)), e.g. im_position = uo_model_holder->zzget_next_subview_count( ), but you have declared your method without any RETURNING parameter.

Instead of

METHODS ZZGET_NEXT_SUBVIEW_COUNT.

the solution could be for instance:

METHODS ZZGET_NEXT_SUBVIEW_COUNT
  RETURNING VALUE(result) TYPE i.

For more information about it, read:

METHODS, RETURNING - ABAP Keyword Documentation (sap.com)

Can you show me how is the coding? Thanks in advance.
