Subroutines, also known as FORM routines in ABAP, are modular units of code that perform a specific task but do not return a value. They are defined with the FORM keyword and are typically used for performing actions or calculations within a program or function.
Defining a Subroutine:
FORM calculate_discount USING p_amount TYPE p DECIMALS 2
CHANGING p_discount TYPE p DECIMALS 2.
IF p_amount > 100.
p_discount = p_amount * 0.1.
ELSE.
p_discount = 0.
ENDIF.
ENDFORM.
