Question

Hi all,
I did some code like when invalid combinations....then need to raise a request,at that time it showing the error message, but after that error message...when press enter....that work order starts genrating(means start processing).So i need to stop the processing after error message displays even click on enter or save...need to show the same error message.Could u plz help me on this.
Plz check the code below:
IF VIQMEL-QMART = ZCL_CONSTANTS=>C_QMART_M1.
         IF VIQMEL-PRIOK = ZCL_CONSTANTS=>C_PRIOK_1 OR
            VIQMEL-PRIOK = ZCL_CONSTANTS=>C_PRIOK_2.
               IF RIWO00-AUART <> ZCL_CONSTANTS=>C_AUART_PM03.
                  MESSAGE e208(ZPM).
               ENDIF.
         ELSEIF RIWO00-AUART = ZCL_CONSTANTS=>C_AUART_PM03.
                MESSAGE e208(ZPM).
         ENDIF.

hi..
i think you are using  module screen then you will have to use stop after the error message and clear the sy-ucomm or ok_code before stop statement.
MESSAGE e208(ZPM).
clear ok_code.
stop.
but if it were a report then also it depends on ur code.
in report if your code contains an end-of-selection and u are throwing an error message in start-of-selection , then below error message statement if you write stop then end-of-selection still will get executed ..
but if you write an EXIt then end-of-selection wont get executed. it will show directly output screen if there is an write statement to display on screen in start-of-selction.
and if you are throwing an error message at selection screen then no need to use any of the above.
but if you are using an information message then u need to use stop after the i message..
hope this will help u
