1	# BAdI & Enhancement Framework
2
3	Guide for using BAdIs (Business Add-Ins) and the ABAP enhancement framework to extend SAP standard functionality.
4
5	## Workflow
6
7	1. Determine the user's goal:
8	- Finding an existing BAdI to implement
9	- Creating a custom BAdI definition
10	- Implementing a BAdI
11	- Understanding classic vs. new enhancement framework
12	- Using key user extensibility
13	- Extending standard code via enhancement spots
14
15	2. Identify the framework:
16	- New BAdI framework (preferred, ABAP Cloud compatible)
17	- Classic BAdI framework (legacy, `SE18`/`SE19`)
18	- Enhancement spots and implementations
19	- Key user extensibility (no-code)
20
21	3. Guide implementation following best practices
22
23	## BAdI Framework Overview
24
25	### New vs. Classic BAdIs
26
27	\| Aspect \| New BAdI Framework \| Classic BAdI Framework \|
28	\| -------------------- \| ------------------------------- \| ---------------------- \|
29	\| Transactions \| ADT or `SE18`/`SE19` \| `SE18`/`SE19` \|
30	\| Enhancement Spot \| Required container \| Not applicable \|
31	\| Multiple Use \| Always multiple-use \| Configurable \|
32	\| Filter \| Filter types supported \| Filter values \|
33	\| Fallback Class \| Supported \| Not available \|
34	\| ABAP Cloud \| Supported (released BAdIs only) \| Not available \|
35	\| Recommendation \| Use for all new development \| Maintain existing only \|
36
37	## Creating a Custom BAdI
38
39	### Step 1: Create Enhancement Spot
40
41	```
42	ADT: New → Other ABAP Repository Object → Enhancements → Enhancement Spot
43	Name: Z_ENH_SPOT_TRAVEL
44	```
45
46	### Step 2: Define the BAdI Interface
47
48	```abap
49	INTERFACE zif_badi_travel_validate
50	PUBLIC.
51	METHODS validate
52	IMPORTING
53	is_travel TYPE zstravel
54	CHANGING
55	ct_messages TYPE bapiret2_t
56	RAISING
57	cx_badi_not_implemented.
58	ENDINTERFACE.
59	```
60
61	### Step 3: Define the BAdI in Enhancement Spot
62
63	In the enhancement spot, add a BAdI definition:
64
65	\| Property \| Value \|
66	\| ------------------ \| ------------------------------------- \|
67	\| BAdI Name \| `ZBADI_TRAVEL_VALIDATE` \|
68	\| Interface \| `ZIF_BADI_TRAVEL_VALIDATE` \|
69	\| Multiple Use \| Yes (allows multiple implementations) \|
70	\| Fallback Class \| `ZCL_BADI_TRAVEL_FALLBACK` (optional) \|
71
72	### Step 4: Create Fallback Class (Optional)
73
74	```abap
75	CLASS zcl_badi_travel_fallback DEFINITION
76	PUBLIC FINAL CREATE PUBLIC.
77	PUBLIC SECTION.
78	INTERFACES zif_badi_travel_validate.
79	ENDCLASS.
80
81	CLASS zcl_badi_travel_fallback IMPLEMENTATION.
82	METHOD zif_badi_travel_validate~validate.
83	"Default behavior when no implementation is active
84	ENDMETHOD.
85	ENDCLASS.
86	```
87
88	### Step 5: Call the BAdI in Your Code
89
90	```abap
91	"Get BAdI handle
92	DATA lo_badi TYPE REF TO zif_badi_travel_validate.
93
94	GET BADI lo_badi.
95
96	"Call BAdI — loops through all active implementations
97	CALL BADI lo_badi->validate
98	EXPORTING is_travel = ls_travel
99	CHANGING ct_messages = lt_messages.
100	```
101
102	### With Filters
103
104	```abap
105	"Define BAdI with filter
106	"In Enhancement Spot: add filter type COUNTRY (type LAND1)
107
108	"Get BAdI with filter
109	GET BADI lo_badi
110	FILTERS country = ls_travel-country.
111
112	CALL BADI lo_badi->validate
113	EXPORTING is_travel = ls_travel
114	CHANGING ct_messages = lt_messages.
115	```
116
117	## Implementing an Existing BAdI
118
119	### Step 1: Find the BAdI
120
121	Methods to find a BAdI:
122
123	- ADT search: Search for BAdI name or enhancement spot
124	- Transaction `SE18`: Browse BAdI definitions
125	- Breakpoint on `GET BADI`: Set breakpoint at `CL_BADI_INTERNAL_FACTORY=>GET_BADI` to find BAdIs called during a process
126	- Documentation: Check SAP documentation or community for BAdI names
127
128	### Step 2: Create Enhancement Implementation
129
130	```
131	ADT: New → Other ABAP Repository Object → Enhancements → Enhancement Implementation
132	Name: Z_ENH_IMPL_TRAVEL_CHECK
133	Enhancement Spot: Z_ENH_SPOT_TRAVEL (or SAP's spot)
134	```
135
136	### Step 3: Create BAdI Implementation Class
137
138	```abap
139	CLASS zcl_badi_impl_travel_check DEFINITION
140	PUBLIC FINAL CREATE PUBLIC.
