Transcripts

hello everyone now we will start with

our next enhancement our next

enhancement is customer exit

in the previous videos we finished our

implicit and explicit enhancements now

we will come on to customer exit yes

what is customer exit it is also an

enhancement enhancement means we will

enhance the sap functionality using

customer namespace we will enhance the

sap functionality in customer namespace

means name should start with Z or Y

now we have three types of customer exit

but this first type of customer exit

function module exit and many time

people will simply use the word function

exit so function module exit or function

exit button the same thing

second type of customer exit is menu

exit

and the third type of customer exit is

screen exit we will go into detail of

each and every type of exit and we will

start with the first type of customer

exit that is function module X

now what is function module accept

with the help of function module exit

will we can add our code to sap programs

with the help of function module with

the help of function module exit you can

add your code to the sap programs now

the question comes where where you will

add your code you will add your code in

the view will add your code in the

function modules

so with the help of function module exit

you can add your code to the sap

programs with the help of what with the

help of function modules

now we will discuss one syntax and then

I will show you how so every function

module exit has a dedicated syntax has a

specific syntax and this syntax is the

most important one and it will play a

vital role in the future in any sap

program the function module exit has a

dedicated syntax but is the syntax

called customer hyphen function and we

have a three digit number this three

digit number can varies from 0 0 to 999

it means if I will go for the example

the function module exits will be

available like call customer hyphen

function001002 and it can go up to 999

so what is function module exit with the

help of function module exit you can add

your code to sap programs it means you

are enhancing sap programs if you are

adding your code to the sap programs it

means you are enhancing sap programs and

how you will enhance with the help of

function modules so we will write our

code in the function modules every

function module exit has a dedicated

syntax and the syntax is call customer

hyphen function and we have a three

digit number

now what I will do I will show you one

program so that you can get a clear

picture what I'm talking about suppose

this is sap program

this is one of the sap include because

it starts with m it means it is a sap

include do we have a function module

exit available you can see yes we have a

function module except because we have a

call customer hyphen function and we

have a three digit number if I will

double click on to this three digit

number is it navigating to one function

module yes it is navigating to one

function module so what we will do we

will write our own code to this function

module we will write our own code to

this function module and is this

function module is the part of this sap

program yes this function module exit is

the part of this sap program so whatever

your logic whatever the logic you will

write into this sap function module will

it trigger in the sap program yes that's

why we are saying we will in case of

function module exit we will write our

code in the function modules

we will write our code into this

function module and this function module

is the this function module exit is the

part of this sap program so our logic

will automatically trigger

now what we will do we will take a

requirement and we will achieve that

requirement full flash through function

module exit now what is our requirement

I will go to va01 transaction code that

is va01 transaction code with the help

of va01 transaction code you can create

sales order

I'm giving some order type and I am

pressing enter

now we have a requirement from the

customer but customer is saying I have

only one soul to party

so I will not fill sold to party it

should be automatically populated and

you can just see what is this

requirement sap has not provided this

it's a additional requirement from the

customer in sap transaction code va01 it

means in this sap transaction code or in

this sap program we have to write our

own code to fill this sold to party and

just now few minutes back we covered if

you want to write your own code can we

achieve this requirement through

function module exit yes because

function module exit allows us to add

our own code to the sap programs so this

particular part that how we will go for

this particular requirement and how we

will achieve this requirement we we will

go for the next video we'll continue in

the next video so what is the summary of

this video

we discussed customer exit is of three

types so we have function module exit we

have screen exit and we have menu exit

function module exit with the help of

function module exit you can write your

own code to the sap programs with the

help of function modules so every

function module exit has a dedicated

syntax called customer hyphen function

and we have a three digit number

that three digit number will varies from

zero zero zero to nine nine nine and

then we took one requirement that

customer wants sold to party by default

in va01 we will achieve this requirement

in the next video thank you
