Error when using record group type as param in a function in where clause

Question

Hi folks.
I have a record type defined in a packages specification. I have to use this record as parameter to call a function. I am able to call the function if as return its value to a string variable. However, the function should be called into a query to compare the returned value and this code is not compiled.
The code is below:
DECLARE
l_line_group_rec INL_CUSTOM_PUB.inl_ship_headers_rec;
l_name VARCHAR2(100);
l_count NUMBER;
BEGIN
l_name := INL_GET_PARTY_SITE_NAME(l_line_group_rec); -- Compiling successfully
SELECT COUNT(1)
INTO l_count
FROM dual
WHERE INL_GET_PARTY_SITE_NAME(l_line_group_rec) = 'Allied Manufacturing'; --- Error when compiling
END;
I got the error: PLS-00306: wrong number or types of arguments in call to 'INL_GET_PARTY_SITE_NAME'
I would like to know if there is any restriction in using record type as parameter in where clauses or if there is another way to do it.
Thanks in advance

Hi.
The definition of INL_GET_PARTY_SITE_NAME:
FUNCTION INL_GET_PARTY_SITE_NAME(p_line_group_rec INL_CUSTOM_PUB.inl_ship_headers_rec) RETURN VARCHAR2 IS
l_party_site_name VARCHAR2(100);
BEGIN
l_party_site_name := 'Allied Manufacturing';
URN l_party_site_name;
END INL_GET_PARTY_SITE_NAME;
Thanks.
