DFFs not imported - creating receipt using API

Hi all,

I'm creating a package to create receipts using API.  I tried passing DFFs but the values are not imported.  I'm very new to SQL so need help.

The script looks like this:

CREATE OR REPLACE PACKAGE body DLI_FPM_API_CALLS AS
procedure create_cash_receipt
(....,
...,
p_attribute_category in varchar,
p_attribute1 in varchar,
p_attribute2 in varchar,
p_attribute3 in varchar,
p_attribute4 in varchar,
p_attribute5 in varchar,
p_attribute6 in varchar,
o_msg_data out varchar2)
is

....;
.....,

TYPE attribute_rec_type IS RECORD(
p_attribute_category  VARCHAR2(30),
p_attribute1          VARCHAR2(30),
p_attribute2          VARCHAR2(30),
p_attribute3          VARCHAR2(30),
