Displaying Error message as Pop up in ME21N Transaction
I need to display error message as a pop up while creating or changing PO ( for eg. vendor field validation) in ME21N Screen. I am using BADI. I was able to get the error message displayed successfully. But when I want to display in Pop up, it is not coming as error rather it is only displaying message. I tried the addition display like I or A, but only E and W type messages are working. I also tried Pop up FM's like POP_UP_DISPLAY_MESSAGE, POPUP_DISPLAY_TEXT but it cannot be displayed as error message.
But We can change the settings to display it as pop up but it will affect all transactions. Any helps????
