There are multiple ways to check if a string ends with a specific substring in ABAP:

1. Using STRLEN and Substring Extraction

DATA: lv_string   TYPE string VALUE 'Hello ABAP',
      lv_suffix   TYPE string VALUE 'ABAP',
      lv_length   TYPE i.


lv_length = STRLEN( lv_suffix ).


IF lv_string+STRLEN( lv_string )-lv_length(lv_length) = lv_suffix.
  WRITE: 'String ends with ABAP'.
ELSE.
  WRITE: 'String does not end with ABAP'.
ENDIF.

2. Using MATCHES Operator (ABAP 7.40+)

DATA: lv_string TYPE string VALUE 'Hello ABAP'.


IF lv_string MATCHES '.*ABAP$'.
  WRITE: 'String ends with ABAP'.
ELSE.
  WRITE: 'String does not end with ABAP'.
ENDIF.

3. Using FIND with FROM Parameter

DATA: lv_string TYPE string VALUE 'Hello ABAP',
      lv_suffix TYPE string VALUE 'ABAP',
      lv_pos    TYPE i.


FIND lv_suffix IN lv_string FROM ( STRLEN( lv_string ) - STRLEN( lv_suffix ) + 1 ) MATCH OFFSET lv_pos.


IF sy-subrc = 0 AND lv_pos = ( STRLEN( lv_string ) - STRLEN( lv_suffix ) ).
  WRITE: 'String ends with ABAP'.
ELSE.
  WRITE: 'String does not end with ABAP'.
ENDIF.

Best Practices

MethodBest Use Case
Substring (STRLEN)Best for all ABAP versions
MATCHES (Regex)Simple & powerful (ABAP 7.40+)
FIND with FROMUseful when position matters

If you are using ABAP 7.40 or later, the MATCHES operator is the cleanest solution.
