Got the data from your link, Thanks for that,
Tried many method but none of those worked, found a method to work around it. 
Order:
First 1000
LOAD
order_id,
customer_id,
order_status,
order_purchase_timestamp,
num(timestamp(floor(timestamp(timestamp#(order_purchase_timestamp,'YYYY-MM-DD hh:mm:ss'),'YYYY-MM-DD hh:mm'),1/(24*60)),'YYYY-MM-DD hh:mm')) as Test,
Left(order_purchase_timestamp,len(order_purchase_timestamp)-3) as CalenderKeyField,
order_approved_at,
order_delivered_carrier_date,
order_delivered_customer_date,
order_estimated_delivery_date
FROM [lib://DataFiles/olist_orders_dataset.csv]
(txt, codepage is 28591, embedded labels, delimiter is ',', msq);

MinMaxDate:
LOAD
Floor(num(Min(CalenderKeyField))) as MinDate,
floor(num(Max(CalenderKeyField))) as MaxDate
RESIDENT Order;

Let vMinDate = peek('MinDate', 0, 'MinMaxDate');
Let vMaxDate = peek('MaxDate', 0, 'MinMaxDate');
Let vDays = Floor(vMaxDate - vMinDate +1);
DROP TABLE MinMaxDate;

TimeCalendarField:
Load
recno(),
date(($(vMinDate) + (recno()/(24*60))-1),'YYYY-MM-DD hh:mm') AS CalenderKeyField
AutoGenerate ($(vDays)+1)*24*60;

Trying other ways to see if any how the time function can work on this.
