module pool programming

Former Member — Fri, 25 Jul 2008 13:23:16 GMT

hey,

i have 2 screens in which for the same field i need to display F4 help thru

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'.

how do i modularize my code ?

currently in screen 100, under PAI i have

FIELD KUNNR MODULE XXXX.

and in a separate include i have

MODULE XXXX INPUT.

endmodule..

i need a similar code for screen 200, but i dont want to replicate the code..

so where and how do i write a single piece of code for F4 help and call that (i need to pass the field as paramater i suppose). can anyone explain clearly and give me sample code ? thks

Sdnuser,

i think you need to have your code replicate casue PAI is seperate for both screen so we cant use the FM for both screen in one hit.

either you can use macro and use this marco in both screen here you can save effrot for replicate your code.but its not a good idea.

Call a perform in both the Modules. and write your code in the perform.

Does that work?
