Processing screen fields

Posted on Oct 26, 2006 at 04:11 PM 29 Views

HI all,

How can I process screen fields in a PAI module.

I put a new module in the PAI of the screen 1229 of the program SAPLMEGUI (transaction me21n).

I can read the field I want in the debugger

(mepo1229-submi) but if I try to read this field in my module I've got this error:

Field "MEPO1229-SUBMI" is unknown

How can it be unknown in the module and known in the debugger???

    Hi Michel,

    One thing u can do is, just declare the structure mepo1229 as a global field. so that what ever the value u enter on screen will be transfered to this structure just before PAI. i think it will solve ur problem.

    Rgds,

    Hi

    Where do you have defined your module?

    Hi,

    Not all the data in all screens are accessible during the debugging time.

    The reason for this is based on the program code, suppose if there is a function call, control goes to the function module code, here only parameters that are passed the functional module are visble to the debugger.

    Thanks,
