Because of a place in the application where the code was not correct, some records gets added without a value in that field. However, we have the value in the InvoiceDetail transaction table, which contains several detail records to that invoice, and the last one contains the timestamp I need to plug in my master table.

If you're using SQL Server 2008 or up, I suggest to use your select statement as cte and use MERGE command to do the UPDATE.
