calling external screen through VA01

[Former Member]

Dear All,

When the user enters a value in quantity filed of VA01 , after accepting

the value it should substract the value multiplied by some other value

from the quantity entered

..For example if the qty enterd is 100 kg and the value entred is 5 then

it shuld substract 5 * 4 i.e. 20 from 100 and replace the quantity by 80

in the line item.

What is the user exit to accomplish the same.

I hope the function module EXIT_SAPMV45A_005 is useful for this. Pleasecheck it in debugging mode, what data it will be taking.

put a breakpoint in line 25( case sy-subrc)

Now run your transaction

at the point of your requirement

when it enters abap debugger

provide exit_name and note down the exit
