SAP ABAP: How to Check if String Contains Substring (Methods)

In SAP ABAP, you can check if a string contains a specific substring using various methods:

1. Using `FIND` statement

DATA: lv_string TYPE string VALUE 'Hello ABAP World',
      lv_substring TYPE string VALUE 'ABAP',
      lv_result TYPE i.

FIND lv_substring IN lv_string.
IF sy-subrc = 0.
  WRITE: 'Substring found'.
ELSE.
  WRITE: 'Substring not found'.
ENDIF.

If sy-subrc = 0, it means the substring was found.
If sy-subrc ≠ 0, the substring was not found.

2. Using `CS` (Contains String) Operator (from ABAP 7.40)

DATA: lv_string TYPE string VALUE 'Hello ABAP World'.

IF lv_string CS 'ABAP'.
  WRITE: 'Substring found'.
ELSE.
  WRITE: 'Substring not found'.
ENDIF.

The CS operator checks if the string contains the given substring.

3. Using `MATCHES` with Regular Expressions (from ABAP 7.40)

DATA: lv_string TYPE string VALUE 'Hello ABAP World'.

IF lv_string MATCHES '.*ABAP.*'.
  WRITE: 'Substring found'.
ELSE.
  WRITE: 'Substring not found'.
ENDIF.

This method is useful if you need pattern matching.

Which method you choose depends on your ABAP version and requirements! 🚀
