11 - Enhancements & Modifications - Customer Exit - Function Module Exit Part1
Summary
TLDRThis video introduces customer exits in SAP, a method to enhance SAP functionality using a customer namespace. It explains three types of exits: function module, menu, and screen exits. The focus is on function module exits, which allow adding custom code to SAP programs through a specific syntax 'CALL CUSTOMER-FUNCTION' followed by a three-digit number. The video demonstrates how to implement a function module exit in an SAP program and hints at a future example involving a customer requirement for automatically populating the 'Sold-to Party' field in the VA01 transaction code.

🛠️ SAP Enhancement Through Customer Exits
This paragraph introduces the concept of customer exits in SAP, a method for enhancing SAP functionality using a customer namespace. It explains that enhancements are achieved by using names starting with 'Z' or 'Y'. The speaker discusses three types of customer exits: function module exit, menu exit, and screen exit. The focus is on the function module exit, which allows for the addition of custom code to SAP programs via function modules. The paragraph also introduces the specific syntax for function module exits, 'CALL CUSTOMER-FUNCTION', followed by a three-digit number ranging from 000 to 999. The speaker provides an example of how to navigate to a function module within an SAP program and emphasizes the role of this syntax in future SAP programming.
📝 Implementing Custom Logic with Function Module Exit
The second paragraph delves into the practical application of function module exits by discussing a customer requirement for automatically populating the 'Sold-to Party' field in the VA01 transaction code, used for creating sales orders. The speaker explains that SAP does not provide this feature by default, necessitating custom code. The paragraph outlines the approach to achieving this requirement through function module exits, where custom code is written into function modules that are part of the SAP program. The speaker promises to demonstrate how to fulfill this specific requirement in the next video, concluding with a summary of the discussed customer exits and their purposes.

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
