Error message at the selection screen while processing screen logic

[Former Member]

Hi All,

I need to show error message at the selection screen.

I am calling the screen inside the START-OF-SELECTION, and processing the calculation and putting the data into i_final internal table. If internal table I_FINAL is empty I have to show error message saying ' DATA is empty' , this error message should be shown at the SELECTION SCREEN (Report input screen 1000) and provide the user to enter the input values once again.

But whenever I am populating error message, I am getting a pop up to chose exit, and process is terminating.

Since I am in the middle of the screen processing whenever I am giving a error message.

Please let me know how can I populate error message without terminating the process while I was in the middle of the screen processing logic.

Regards,

You can validate by using the

AT SELECTION-SCREEN Event

and raising error message type

message text-xxx type 'E'.

it will allow user to enter correct input.

Put if condition where u r filling the I_FINAL TABLE.

After filling the I_FINAL table put condition like as follows

If I_FINAL[] is not intial.

message 'Data is Empty' type 'I'.

exit.

endif.

It will take you to the selection screen.

No, it's going to ouput list with empty data records.

Since I am using SET_TABLE FORFIRST_DISPLAY function to display the alv list in the Table control.

Hi

Use the statement:

Use AT SELECTION-SCREEN ON FIELD,

AT SELECTION-SCREEN ON BLOCK,

AT SELECTION-SCREEN events to perform validation on your selection screen which will allow you to throw a error message in the status bar and will allow the user to enter a new value, you can use message type E & W...

thanks

hi

If u are trying to validate a field use

AT SELECTION_SCREEN ON <field>

if want to validate a block

AT SELECTION SCREEN ON <block>

If Universal Validation

AT SELECTION SCREEN

and display a 'E' Message inside the block.

You can Enter Correct Value and start processing Forward.

hope this will help.
