I have created an extra tab in VL01N which contains 6 fields. the same tab i have also created in VF01.
now when user enters data in VL01N data should get copied while creating invoice..
I have searched SDN, Googled about it.
i found that i have to implement a routine.. I have never worked on routine before.
So please can anybody help me with how to create a custom routine. i dont want the steps, i want what pre-requisite i need for writing custom routines, how can i write the code? i have gone through some standard routines for eg LV60A003.
But i did not get anything from that. so please can anyone help.
Is there any other way than writing routine for implementing above scenario.
