Work on userexits

[Former Member]

Dear experts,

I am going to start work on an assignment which includes enhancement of transactions

related to PR like ME21N,ME22N,ME23N,ME29N.

Enhancement include incorporating two fields in detailed section.

How can i achieve this..

I came to know that i have to use customer exits and make changes in Uesr exits,Screen exits,

menu exits finally making sure that data is being populatd on to corresponding tables.

But as i am new to userexit,i am not able to make out how to start.

Can somone guide me here ?

But what code to write.

It is just like a person has coded

Microsoft Office and opens a text file while

giving demo.

Further he ask me aditya wherever i stopped last

you code from there and add a grammatic check module now.

I am not aware of anything ,what to decide to code ?

MM06E005 is the User Exit that allows you to add custom fields in the transaction open this in CMOD and implement the logic

MM06E005  Customer fields in purchasing document

I think,not only in user exit but may be also in screen exits and

then menu exits , i will be required to modify

ME21N,22N,23N,29N to include the functionality of capturing two additional fields.

However,is it that i will be required to add these field in ekpo

table also on my own to existing structure?
