I have to use the subtotal function to gain totals based on the month that a particular item was posted to the GL (accounting stuff) Each row is a separate record. The problem is that when I pull data from our enterprise management system it does not give me information for posting date in a date format. instead it gives something similar to: "07/05/11 17:21:29CSCRI". since I have to sort and subtotal this data based on date, it proves difficult to get the information I need. is there a way to take "07/05/11 17:21:29CSCRI" and turn it into something useful? would it be easier to manually sort by the posting date column and manually create the subtotals?
