Table control Overwrite ok_code code.

[amysh95]

Hey,

I made a table control and use my validation in PAI as.

in PAI.

loop at itab.

chain.

field1..

field 2..

field 3 module validate.

endchain.

.

.

now on screen if i press my back (pf-status) this validation code overwrite my back code (leave to screen 0.).

How can i resolve this issue?

Take a look at the SAP Help for ON EXIT-COMMAND.

What means "this validation code overwrite my back code" ?

Have you defined a variable in the ok code field for the screen? (It's generally the last field on the element list).

yes. i already did.

As I already said. If you want the BACK/EXIT/CANCEL functions to override the PAI logic then you can use on-exit command.

1) In your gui status for the function code BACK set the Functional Type to E (Exit Command)

2) In your PAI make this your first statement (before your PAI logic):

MODULE handle_exit AT EXIT-COMMAND.

loop at itab.

chain.

field1..

field 2..

field 3 module validate.

endchain.

3) Code your exit module like you want:

MODULE handle_exit INPUT.
CASE ok_code.
WHEN 'BACK' OR '????'.
SET SCREEN 0.
LEAVE SCREEN.
ENDCASE.

ENDMODULE.

first if you defined back button in gui status = type E (on exit command) and call a module with extend: ON EXIT-COMMAND, when you click back button it will not go through the chain loop but go to that module.

second, you said "this validation code overwrite my back code", so i must guess you didnt define back button as exit type also you change or clear ok code inside validation method.
