🛠 Implementing Implicit Enhancements

This paragraph delves into the practical steps of implementing implicit enhancements. The speaker guides through the process of enhancing a SAP function module by adding an enhancement operation at the start of the module. They demonstrate how to create an implementation with a custom name, such as 'Z_implementation_for_file_select', and how to write code to alter the title from 'File Select' to 'Choose File'. The importance of testing the enhancement with breakpoints is highlighted, ensuring that the changes work as expected. The speaker also explains the process of activating the enhancement and verifying its functionality within the SAP program.

10:05

🔄 Reversing Enhancements After Practice

The final paragraph emphasizes the importance of reversing any enhancements made during practice sessions to prevent interference with the system and other users. The speaker reiterates that while it is necessary to work on enhancements and modifications in projects based on requirements, it is equally important to undo these changes after practice. They demonstrate how to undo an enhancement by returning to enhance mode and using the undo function, which restores the original title 'File Select'. The speaker concludes by reminding viewers of the significance of this practice for maintaining the integrity of the SAP system.

Keywords

💡SAP

SAP is a German multinational software corporation that produces enterprise software to manage business operations and customer relations. In the video, SAP is the platform where the user is practicing and enhancing functionalities, particularly through function modules and implicit enhancements.

💡Function Module

A function module in SAP is a pre-defined piece of code that performs a specific task and can be called from other programs. The script discusses using the function module 'F4_file_name' to implement file handling and to modify its behavior through enhancement.

Transcripts

foreign

we will continue the topic

enhancements and we will take a

requirement and we will achieve that

requirement and especially for this

topic I always always suggest whenever

you are practicing this topic please

please always undo after that because

you are going for implementations in sap

logic so if you are practicing please

undo also after that so that it will not

hamper the other people yes now we will

go for a example and we will achieve

that requirement using implicit

enhancement

suppose we'll go for a program

when we did the file handling

suppose I am running this program file

handling program

whenever I will click on to this help

button F4 help button

it is showing my presentation server if

you remember during the file handling

topic we covered this presentation

server is showing by the function module

F4 underscore file name with the help of

this function module you can select the

file and it will return the full path of

the file suppose this is sap function

module which is helping us to achieve

this functionality suppose if I am

running

how this function module help

when you click onto this F4 button

with the help of that function module it

is showing our presentation server

you selected the file from the desktop

and that function module returned you

the full path of the file now we will

take requirement and we will see how we

can achieve that requirement

through implicit enhancement

if I will click on to this F4 button

it is showing us the presentation server

or I'll say it is showing our desktop

now what customer is saying

we are getting a title file select see

we have not given this title it is

coming from sap function module F4

underscore file name now what customer

is saying

rather than file select I won't suppose

upload file customer is not comfortable

with this title file select or customer

is saying I want a title choose file it

means in this sap function module you

need to replace file select with I'll

say suppose choose file we will see how

you can achieve this requirement

now we will go for this function module

F4 underscore file name this is sap

function module we will double click

if you see in this sap function module

sap has again one function module WS

file name get and if you see

here is that title if I will double

click on this title which sap is

providing you can see title is file

select and this is appearing there now

rather than this file select we bought

or customer bought a title choose file

so just see how I can achieve this

requirement through implicit enhancement

so

sap is passing that title file select

it is going into this function module

okay now in this function module can we

do the implicit implementation or

implicit enhancement at that top or at

the last yes we can do see sap is giving

the title file select can I replace that

title with choose file yes I can do

because at the starting itself see as CP

is providing the title file select

when the file select came into this

function module I will replace that

title with choose file at the starting

itself so we will achieve this

requirement through implicit

implementation or we can say implicit

enhancement and we will go for same to

same practical exercise

in this program firstly how you can see

the implicit point

add it

enhancement operation

show implicit enhancement option

you can see we have a implicit point at

the starting also we have a implicit

point at the last also so at the

starting itself I will replace file

select with choose file

so how to do that now

you all know you cannot change sap

function module okay but can you enhance

sap function model yes you can enhance

so I will click on to enhance button

once you clicked on to enhance button

you can right click on the point this is

implicit point

you can go for enhancement operation and

you can go for create implementation

yes I want to write a code so I will

click on to code

I will click on to create implementation

and we will give the implementation name

starting with z and this is our most

important understanding you are

enhancing sap functionality but in which

namespace customer name space that's why

it is called as enhancement so I will

write suppose Z

implementation

for file select

and I will give some serial number

implementation

change the title

I will go for okay

I will save this as a local object

I will choose the implementation

now you just remove this comment

now you can see we have a option to

write the code

see this is the title title sap is

giving file select but we will change it

to choose file so I am writing title is

equal to suppose I am saying choose 5.

and you see we are changing the sap we

are enhancing the sap functionality

itself

I'll go for activate

now we will see is it working fine or

not so for the best understanding I'll

put a break point on my implementation

logic

and we will see is it working or not we

will run the program

whenever we will click on to this F4

button sap will call this function

module will go step by step

I will click on to this button

so sap called our function module

and you can see this is our

implementation which we wrote inside

that function module okay I'll just go

again to show you step by step process

I will just double click on to this

function module

I will go to this WS file select and

there we will I'll put the breakpoint

I'll show you step by step how we will

go

I am executing

whenever I will click on to this F4

button

sap is calling our function module F4

underscore file name I will go inside

this function module

inside this function module we have WS

file name I'll come to this function

module see up to this level the title is

file select file selected if I will go

inside this function module we are

replacing file select with choose file

this is the logic which we wrote this is

the enhancement which we wrote now you

can see title is choose file if I will

execute

now you can see the title change to what

choose file because we change the title

so this is by just one example which we

took that how we can sometimes achieve

the requirement by using implicit

implementations now I'll again repeat

after practice you should always always

undo these things because this is very

critical things because you are changing

the sap or you you are chain you are

enhancing the sap logic itself so after

practice please please undo all those

things yes yes in the projects yes we

have to work on all these enhancements

and modification depends upon the

requirement but if you are practicing

those things so after practice please

undo all those things so that it should

not hamper the other people

so I will also undo I'll simply go to

enhance mode

right click and I will undo this

implementation so that that title will

again change to file select only so if I

will show you my program that title will

be again we'll see

its file select only because we undo our

implementation so this is just one

example how to do the implicit

implementation go for implicit point it

will be at the top or at the last of any

sap function module program

subroutines and you can create the

implementations there and you can write

that code so that's it in this video

thank you
