Public Method defined in a subclass cannot be used

Former Member — Wed, 31 Oct 2012 21:01:31 GMT

I'm struggling with a subclass defined in the abstract class CL_BROWSER. An added method is Public, but the compiler reports the method is unknown or protected or private. Looked through the Netweaver document on Abstract classes, but did not find that subclasses can not be extended.

Did I miss something?

I found it. For abstract class subclasses, methods must be called via dynamic algorithm.

Hi,

Can you please elaborate on -

methods must be called via dynamic algorithm

What exactly is the "dynamic algorithm" you're talking about?

BR,

In the SAP 7.0 Netweaver documentation, find "Declaring and Calling Methods" and search for Dynamic Method Call.

One will find:

Using the standard ABAP
parenthesis semantics you can call methods dynamically.

Calling an instance method meth:

CALL METHOD ref->(f)

Basically, the name of the method being called is placed in variable f. In my case, there is also a parameter in the method I defined, so I had to create an itab of type ABAP_PARMBIND_TAB and pass it in the call using the addition PARAMETER-TABLE.

CALL METHOD ref->(f) PARAMETER-TABLE itab

This compiles clean.
