What is ENHANCEMENTS in SAP.

 ENHANCEMENTS in SAP ABAP. 

These are used to add extra intelligence to SAP standard programs to suit the business requirements. If we want to add extra code to SAP standard programs, if we go for change mode system asks for access key. Instead of this, SAP has provided hooks where we can write the code. These hooks are enhancement spots. If a code is written in theses spots along with the normal program the code written in these spots is also executed. There are two ways to enhance the SAP standard code.

User Exits

BADIS (Business Addins)

If user exits are used one time in any project it can not be reused. But Badis can 

be used any no of times.

There are 4 types user exits.

Function module exit

Field exit

screen exit

Menu exit

Exits are defined at package level. So we want to enhance any T-code first we 

have to find out the package for that T-code. Then we have to find out the exits present in that package. For finding the exits present in a package we have to use SMOD T-code. After finding the suitable exit for writing the code we have to use CMOD T-code.

Difference between Implicit & Explicit Enhancement In SAP ABAP.

Ques: What is the difference between Implicit & Explicit Enhancement?

Implicit & Explicit Enhancement in SAP ABAP.

Answer:

 Under implicit enhancement you can write your own code

 Adding Z-enhancement in already existing one is called Explicit enhancement

Example:

 Go to SE93

 Transaction Code: VA01

 Display

 Double click on Program Name

 You will find a spot given by SAP

 Enhance

 Right click ES_SAPMV45A

 Enhancement Implementation ----Create Implementation

D. Once the Access Key is get you can do modification.
E. After that enter the routine number ,description and insert the Access Key
F. Next new  ABAP Editor will open and required code can be copied from Standard SAP Routine and Custom Code Can be developed.
G. Next the coding is completed you  have to Activate the Routine
H. Select the Routine and Go to Edit – Activate
I. Ensure that Active check box is ticked upon Activation of the Routine.
J. Double click on the routine will enter into ABAP Editor, You  have to generate the Routine
K. Go to Program and select Generate
L.A screen pops up with the related Main Programs  and select all required main programs wherever the Routine is being called.
M. Next the Routine is Generated and Activated, You need to configure the Routine in the config.

KE51 transaction how to make field (Address) required in SAP ABAP.

KE51 transaction how to make field (Address) required in SAP ABAP.

SAP does not provide any configuration and user exit to make fields in Address tab required in transaction KE51.After that debug ABAP Code, I found the way that you need to create enhancement point in include program LRKPMF05 in subroutine md_user_command_handle.

This example we want to make field Street, City, Country and Region is required when user click SAVE. Please check out this ABAP Code below.

BADI For Material check In SAP ABAP.

BADI FOR MATERIAL CHECK

Read More BTE...

The Requirement for information message .When you creating a material if material group is A10 and division is: 05.

(This is only use for: As it needs two information for the material and user wants information message while saving the material. we can’t use field exit for this).

First step:

How to find appropriate BADI for this requirement??

Go to T-Code:--SE24

PUT:-- CL_EXITHANDLER.

NEXT:-Click display button.
Add the break- point into Class CL_EXITHANDLER’s GET_INSTANCE method.

Next:-Go to T-code MM01, After that you create a material and try to save it. it stops at many locations with different values of EXIT_NAME. (After checking into Se18 we got the BADI_MATERIAL_CHECK which can be used for our requirement.

    §  It has a method CHECK_DATA which is called before saving the material.

    §  It also has WMARA table as input data (Material Group and Division comes in MARA table).

Step 2:

Go to Transaction code SE18.

Open BADI: BADI_MATERIAL_CHECK.

Go to menu option Implementation  Create.

Read More BTE...

Step 3:

Put the name of implementation as ZMM_MAT_CHECK.

Step 4:

Double click on the method CHECK_DATA.If you notice the input parameters we have many data related to batch, material and storage location etc.

For our requirement we need material group and division which exist in WMARA. Put the below code inside the method then activate the class and method.

IF WMARA-MATKL EQ
‘A10’
AND WMARA-SPART EQ
’05’.
message
‘Material creation for this Group should be avoided for animal products!!’
TYPE
‘I’.
ENDIF.

This code is just checks the material group and division.

Step 5:

Go back and activate the implementation.

Step 6:

For this go to transaction MM01 and try to create a material.

(if you are confused use material name as CH004 ,

Industry sector as Animal Health and

Material Type as Beverages )

Click on the ENTER Button and from the view select BASIC DATA 1.

Step-7: First Of all Create a Function Group (ex. ZSN_BTE_FG) in t-code SE80  àActivate.

Step-8: Next click on Sample code à Copy Standard SAMPLE_INTERFACE_00001120 Function Module into  custom function Module (Ex. ZSN_BTE_FB60_FM).

Step-9: Change the custom Function Module ZSN_BTE_FB60_FM à Put Your Condition In This Function Module à Save à Activate
