Hello.

Put a break point on the if zstudent-name co sy-abcde. statement, check the value of the fields, doing that you will get an idea of why if showing the error.

Hi,

to continue with error messages write the code under MODULE EXIT AT EXIT-COMMAND.

in this module

case sy-ucom or ok_code.

when 'BACK'.

leave program.

when'EXIT'.

leave program.

endcase.

Venkatesh,

If the field which is causing the error is a screen field, try this.

PROCESS AFTER INPUT.

CHAIN.

FIELD: scree-field module error_check.

ENDCHAIN.

Once again try placing other scree-fields in the chain which you want to navigate after getting error on one screen-field.

hi kishore,

i just tried with it but after validating itz not proceeding further.

Re: dialog programming field validation problem.

former_member225688 — Mon, 18 Feb 2013 17:23:19 GMT

Can you please post your code here . So that i will check and let you know where exactly the error is .

At least sceen logic and the module which is not proceeding further.

Or just debug and check why its is not proceeding further. Was it looping at the same time. I mean in a infinite loop or there is some other problem.

hi dnyan,

i had attached the codes below please check with it. I had did validation module in screen 1000...

Re: dialog programming field validation problem.

former_member225688 — Tue, 19 Feb 2013 09:44:32 GMT

Hi Venkatesh,

I have checked the code .

And found that every time the

IF zstudet-NAME co SY-ABCDE.

IF ZSTUDET-ADDRESS CO SY-ABCDE.

ELSE.

message e000 with text-001.

ENDIF.

else.

message e000 with text-001.

ENDIF.

it gets failed.

As if you put a beakpoint there and check you could understand that. If this condition satisfies correctly then the control moves to next module and program will be executed successfully.

For example below code. Where in Name1 and Name2 contains '1234' and condition satisfies successfully.

IF lfa1-name1 EQ '1234'.
   IF lfa1-name2 EQ '1234'.
     ELSE.
       message e000 with 'error'.
       ENDIF.
   else.
     message e000 with 'error'.
      ENDIF.

Please try changing the condition as this means address should contains only A-Z and that will not be a case. please press F1 on the 'CO' you will get all the details of command and you can check why it is getting failed.

Hope this will help you and will resolve your issue .

Regards

Dnyan

-------Code for the module

Module CHECK_IN INPUT.

IF zstudet-NAME co SY-ABCDE.

IF ZSTUDET-ADDRESS CO SY-ABCDE.

ELSE.

message e000 with text-001.

EXIT.

ENDIF.

else.
