user exit - stop processing with error message displayed

[Former Member]

Hi guys,

My scenario is like this

Whil doing migo for the same batch number more than 3 times i should not allow to post the document.

I have the material number and batch number in a seperate ztable

for checking this found out there is an exit.

Enhacmenet - MBCF0002

EXIT_SAPMM07M_001

I have written code in the above exit as

select count(*) from ztable

into t_charg

where matnr eq i_mseg-matnr

and charg eq i_mseg-charg.

if t_charg gt 3.

call function 'POPUP_DISPLAY_MESSAGE'

exporting

titel = 'Error Message'

msgid = 'BD'

msgty = 'E'

msgno = '899'

msgv1 = 'Batch Already Received 3 Times'.

if sy-ucomm = 'OKAY'.

elseif sy-ucomm = 'RW'.

else.

endif.

endif.

The program works fine and gives a pop up message and when i post the document

it still gets posted.

I should not allow to post the document

Help me on this issue?

Regards

this happens with 'POPUP_DISPLAY_MESSAGE'.

so instead use

message e001(zmesg) type 'E'.

gve desription in long text of message

reward points if it helps

thanx for the reply

Ihave created a message class z001 and maintained a message(001)

but when i am trying to activate it says

Field "Z001" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement . . . . . . . . . .

whether i need to include anything in the program for message class
