MODULE LISTE_SHOW_LISTE.

ENDLOOP.

PROCESS AFTER INPUT.

MODULE LISTE_EXIT_COMMAND AT EXIT-COMMAND.

MODULE LISTE_BEFORE_LOOP.

LOOP AT EXTRACT.

MODULE LISTE_INIT_WORKAREA.

CHAIN.

FIELD ZPM_144_EQ_STTYP-EQART .

FIELD ZPM_144_EQ_STTYP-STTYPE_10 .

FIELD ZPM_144_EQ_STTYP-STTYPE_20 .

FIELD ZPM_144_EQ_STTYP-STTYPE_30 .

FIELD ZPM_144_EQ_STTYP-STTYPE_40 .

MODULE INIT_EARTX. <--- my module

ENDCHAIN.

FIELD VIM_MARKED MODULE LISTE_MARK_CHECKBOX.

CHAIN.

FIELD ZPM_144_EQ_STTYP-EQART .

MODULE LISTE_UPDATE_LISTE.

ENDLOOP.

MODULE LISTE_AFTER_LOOP.:

MODULE INIT_EARTX INPUT.

DATA: t_EARTX TYPE TABLE OF T370K_T-EARTX WITH HEADER LINE.

SELECT SINGLE EARTX FROM T370K_T

INTO t_EARTX

WHERE EQART = ZPM_144_EQ_STTYP-EQART AND

Hello John

You should not modify the flow logic of the automatically generated dynpros. Instead, use the maintenance events of the view.

<a href="http://help.sap.com/saphelp_nw04/helpdata/en/91/ca9f0ea9d111d1a5690000e82deaaa/content.htm">Extended Table Maintenance Events</a>

In your case you may use Event 26 before displayed data is output in a list or Event AA instead of the standard data read routine.

Please refer to the SAP documentation for details of implementing this events.

The big advantage over your approach is that when you completely regenerate the dynpros your coding will be lost whereas the events remain.

Regards

Uwe
