with change in integrated system to consolidated system
55
Transport request C
without change in integrated system to consolidated system
56
Transport request T
move the one system to another system
57
Two types of BADIs
Multi-use | Filter-dependent
58
Multi-use BADI
any number of active implementations can be assigned to the same definition BADI
59
Filter-dependent
Using this option we can define the BADI’s according to the filter values to control the add-in implementation on specific criteria
60
User Exits
Implemented as Subroutines
61
Customer Exits
Implemented as Function Modules
62
Type of Enhancements
``` Menu exits Screen exits Function Module Exits Field Exits Function Group Class / Interface Source code-plug in ``` Exits act as Hooks where you can add your own Functionality in addition
63
Limitations of User exits
Cannot be Re-usable. Will be overwritten during Upgrade. Read / Change almost every Data Object which is defined Globally in the Program. Very Easy to manipulate the Data which could result in Erroneous outcome
64
Limitations of customer exits
Concurrent Development is not possible Very Difficult to keep track if the Project is not Created
65
enhancement spots
Used to manage explicit enhancement options. That means you can add your code in standard ABAP code without need of access key, which implies that the standard code is not disturbed. Enhancement spots specify the places where we can add our code in standard SAP
66
Enhancement Point
The position in a SAP ABAP program where enhancement are made. The enhancements, when complied with the current source code work as if it was a part of the source code.
67
Implicit Enhancements
In implicit enhancements SAP provide the space where we will write our own functionality. --> Begin/ end of an include. --> Begin/end of method / FM / form routine. --> End of structure.
