I am writing a report that for now is using data from 2 tables. This report is going to be accessed via CRM and is based on a particular record chosen in CRM therefore my initial dataset is using the "CRMAF" prefixes. This part is working fine
I need to populate a 'From' date parameter value to the minimum date that exists on a related sub table.
For example - assume we have an Orders and OrdersDetails tables
My report has a dataset with a query something like this:
SELECT CRMAF_Ord.OrderNumber,
CRMAF_Ord.CustomerName,
CRMAF_Dt.ProcessedDate
FROM Orders as CRMAF_Ord
Inner Join OrderDetails as CRMAF_Dt
On CRMAF_Ord.OrderNumber = CRMAF_Dt.OrderNumber
Each order could have many order detail records with different 'processeddate' values. I want my 'From' datetime parameter value to display the earliest processeddate value for the given order record that has been selected.
I created a 2nd dataset 'ProcessedFromDate' which is called from my 'From' parameter
SELECT MIN(CRMAF_Dt.ProcessedDate) as 'Processed From'
FROM OrderDetails
This ultimately gives me back the earliest processeddate value that exists for all order detail records, not just the one I have selected.
It seems I need to be able to somehow reference the main dataset or something but not sure how to limi the dates to only the record chosen.
Any help would be appreciated.
Thank you.
