Solved: Assigning Data-Type Select-Option from Report to M...

Former Member · ‎10-17-2007

Hi Specialists,

How can I solve the following task smart? It’s a quiet simple task. In my Report I’ve some Select-Option-Data-Types and I want to assign this data-type an Abpab-Object-Method. Is it possible to do this in a smart fashion. I’ve fight with the Abap-Syntax und at the end I’ve found a tricky way of assigning the Select-Option parameter to the Abap-Object-Method.

If somebody have a smart idea for this problem, pleas let me know.

Thankx.

Hallo Spezialisten,

ich hätte da eine Frage wie man folgende Aufgabe elegant lösen kann.

Es ist ganz einfach, ich möchte von einen Report einen Select-Option-Datentyp an eine Abapobject Methode übergeben. Ich hatte sehr lange gekämpft bis ich ein umständlichen weg gefunden habe die parameter vom reprot an die mehtode zu übergen.

Falls jemand da eine gut Idee hätte wäre mir das nächste mach sehr geholfen.

Danke

Hi,

You want to pass the select-options from the selection screen of the report to the object?

If that's your problem you can use the FM 'RS_REFRESH_FROM_SELECTOPTIONS' to get then of a given report.

Hope it helps you
