hi ,

thanks for ur response sir.

i changed the message type i,but it just showing the message and doesnt make the field for  input again and continuing the next process

[Former Member]

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 miguel,

just did with break points i  found the mistake in validation module it just transferring the control again and again to the field statement and validation module associated with it, not processing further modules.how to correct it help me please. 

[gurunathkumar_dadamu]

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.

[Former Member]

hi kishore,

i tried with chain...endchain too but the same result after executing validation module its not transfering control to the further modules.

regards.

[Former Member]

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

hi kishore,

cant get u iam new to abap could just post some examples please.

   CHAIN.

     FIELD: scrflds-filename,

            scrflds-fspath,

            scrflds-filepath,

            scrflds-filetype,

            scrflds-jname,

            scrflds-dnlty,

            scrflds-dnlin,

            scrflds-dnlas,

            scrflds-dctmpl,

            scrflds-flocn.

     MODULE file_details_check.

   ENDCHAIN.

hi kishore,

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

[former_member225688]

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.

[Former Member]

hi dnyan,

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

[former_member225688]

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 .

hi dnyan,

            i set break point and chekd also changed co but if i remove co itz not working properly if i put co itz showing error... but the values are changing i put a watch point over the screen field and checkd but itz not proceeding further with co. if i add cs instead of co itz not properly validating... so can u tell me any other way to validate char data types.

[former_member225688]

what is the requirement. Address and name should only contain letters or what. So that i can provide the alternative for you .

[Former Member]

hi dnyan,

ya name and address can contain only alphabets no other special characters or numbers.

[former_member225688]

Use below logic it will solve the problem.

IF address CA '123456789!@#$%^&*()'.
write 'wrong'.
ELSE.
write 'correct'.
ENDIF.

Hi Venkatesh,

Try out the code given below,

Use the ON INPUT addition with your module

PROCESS AFTER INPUT

CHAIN.

FIELD: ZSTUDET-NAME,

             ZSTUDET-ADDRESS    MODULE CHECK_IN ON INPUT.

ENDCHAIN.

-------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.

    message e000  with text-001.

     EXIT.

     ENDIF.

ENDMODULE.                 " CHECK_IN  INPUT
