Hello - this is a snippet from my code. I cannot get the nulls to populate the no payments. I have tried a number of techniques (isNull, len=0, combinations of resident tables etc) but to no avail. Please can you help. ![](/legacyfs/online/emoticons/plain.png)
Many thanks, James.
NO_PAYMENT_MAP:
MAPPING LOAD
null(),'NO PAYMENTS'
AUTOGENERATE 1;
map "Last_Paid" using NO_PAYMENT_MAP; //not sure about quotation marks, single quotes, or nothing at all.
PAYMENTS:
LOAD Document_Type,
date(Posting_Date) as Posting_Date,
CA,
Amount as Amount_2
FROM
(qvd)
where Exists(CA)
;
MAX_DATE:
Load
CA,
date(max(Posting_Date)) as Last_Paid
Resident PAYMENTS
Group By CA
;
MAX_DATE_2:
NoConcatenate
Load
CA,
Last_Paid
//I also tried... if(isNull(Last_Paid), 'No Payment', Last_Paid) as Last_Paid
Resident MAX_DATE
;
DROP TABLE MAX_DATE;
MAX_DATE_FINAL:
NoConcatenate
Load *
Resident MAX_DATE_2;
DROP TABLE MAX_DATE_2;
