Hi, I have the code below from my senior, and the code is used to insert Descriptive Flex Fields into the oracle application. Can someone please help to explain the code below? I cannot understand the code at all. For e.g, how do I know which oracle table is this code inserting the DFF, and what does each line of the code means etc. Please kindly help. Thank you.

PROCEDURE new_flex_pkg (p_appl_id in number,
p_flex_name in varchar2)
IS
BEGIN
FND_DESCRIPTIVE_FLEXS_PKG.INSERT_ROW (
v_rowid, p_appl_id, p_flex_name,
'FND_SRS_MASTER', --X_APPLICATION_TABLE_NAME in VARCHAR2,

'N', --X_CONTEXT_REQUIRED_FLAG in VARCHAR2,
