Hi alex,

In the PAI

field fieldname module modulename

v_len = strlen( v_str ).

if v_len = 3.

CALL FUNCTION 'POPUP_FOR_INTERACTION'

EXPORTING

HEADLINE = 'Warning'

TEXT1 = 'Enter 5 character value'

TICON = 'W'

BUTTON_1 = 'Ok'.

endif.

Hi ,

Use this logic when user click button

v_data = strlen( screen-field ).

if v_data = 3.

CALL FUNCTION 'POPUP_CONTINUE_YES_NO'

EXPORTING

TEXTLINE1 = WSC-DECISION_TEXT1

TEXTLINE2 = WSC-DECISION_TEXT2

TITEL = '??? DECISION TIME ???'

IMPORTING

ANSWER = WSC-ANSWER

EXCEPTIONS

OTHERS = 1.

endif.

In the PAI event write this logic.

DATA : V_LENGTH TYPE I.

V_LENGTH = STRLEN( INPUTFIELD ).

IF V_LENGTH <> 5.

*--If length is not equal to 5.

CALL FUNCTIN 'POPUP_TO_DISPLAY'.... to display the message..

endif.

in PAI section:

module check.

in program:

module check.

data: v_len type i.

case sy-ucomm.

when '<your fcode for button>.

v_len = strlen( v_field ).

if v_len < 5.

message w001(zz) with 'Not acceptible'.

endif.

endcase.

endmodule.

in se91 create a message class with name zz and have an entry 001 with a place holder &.

Thanks for the given help but I'm not getting it Wright. I presume the module check is to check the data in the field, but the data is only considered to be written after I press ENTER without passing to next screen. Is there any way to force the field to be read without pressing ENTER.

Best Regards

in my opinion no it is not possibile without press ENTER or another button.

but if you press enter is not obligatory pass to next screen
