FF68 Check Deposit : How to use this transaction ?

Question

Hi,
i try to use Tcode FF68 for Check Deposit but after entering the required information i don't get an FI document (i save but i have one line item in debit).
Please What does this transaction do exactly ? is there any others transactions related to FF68 that i must use too ?
Or i need to do some IMG points before to use it ?
Please help
Regards

Ok, ok - so I have updated the function and it compiled, fine, but now nothing is returned, I thought that a number was returned ?
CREATE OR REPLACE function Y775.compression_ratio (tabname varchar2)
return number
AUTHID CURRENT_USER
is
pragma autonomous_transaction;
-- sample percentage
pct number := 0.000099;
-- original block count (should be less than 10k)
blkcnt number := 0;
-- compressed block count
blkcntc number;
begin
execute immediate ' create table TEMP_UNCOMPRESSED pctfree 0
as select * from ' || tabname ||
' where rownum < 1';
while ((pct < 100) and (blkcnt < 1000)) loop
execute immediate 'truncate table TEMP_UNCOMPRESSED';
execute immediate 'insert into TEMP_UNCOMPRESSED select * from ' ||
tabname || ' sample block (' || pct || ',10)';
execute immediate 'select
count(distinct(dbms_rowid.rowid_block_number(rowid)))
from TEMP_UNCOMPRESSED' into blkcnt;
pct := pct * 10;
end loop;
execute immediate 'create table TEMP_COMPRESSED compress as
select * from TEMP_UNCOMPRESSED';
execute immediate 'select
count(distinct(dbms_rowid.rowid_block_number(rowid)))
from TEMP_COMPRESSED' into blkcntc;
execute immediate 'drop table TEMP_COMPRESSED';
execute immediate 'drop table TEMP_UNCOMPRESSED';
return (blkcnt/blkcntc);
end;
