[SalesForce] Updating Salesforce Date field with MC AmpScript

The documentation on the data extension data types reads:

Date

• A system date
• You can use an AMPscript function to format this value when you present it in a message
• Attributes of a date type will accept dates in various formats, such as 1/1/2005 or January 1, 2005
• All dates are stored in the format MM/DD/YYYY, and if a date is entered in a different format, the system will convert it to the proper format when storing it
• Valid date values begin after 12/31/1772 and before 01/01/10000
• You can add a HH:MM time value following the date value, such as 12/12/2012 12:12 PM.

As long as your data extension uses the data format for the column, and your string is in the proper format according to the above guidelines, you should be ok.

It appears that we do not, however, store as a 24-hour time (which btw is not GMT per se, unless you are not using a timezone offset). A simple fix for this would be to check for AM/PM and add 12 when parsing from the DE, and check for >12 and modify when going back to the DE to store.

To use Concat() to pull individual items together, the string would have to match the above valid date format.

CONCAT(@month,"/",@day,"/",@year," ",@hour,":",@minute," ",@ampm)

This will produce a valid string, especially when using DatePart(), since it returns a string of the segment you requested.

I assume by 'insert values into Lookup fields through AMPscript' you are using the AMPscript Lookup() function? For example, you have defined the variables as lookup functions earlier in your code:

var @FirstName, @LastName, @Id, @Result

set @Id = '001A0110081BM1'
set @FirstName = Lookup('Customers','FirstName','Id',@Id)
set @LastName = Lookup('Customers','LastName','Id',@Id)

Either way, this should work. From looking at your code, my guess is that you are using the field name, not the API name, as 'Account' is not a standard API name in the Salesforce Accounts object. Find the API name of the fields that you are using and include them in your CreateSalesforceObject() function.
