Hi all,

I'm really struggling with this one - I thought it would be easy going into it.

I have a sheet with a data dump containing data on several railcars, taking up approximately 500 rows. Some railcars take up multiple rows, one row for each unique customer, and one railcar can have up to 5 customers' goods on it. What I need to do is get this information separated out onto monthly sheets, based on the departure date of the railcar. Every row of data in the dump has a column with the departure month I need in it, so that would make it seem easy. I have 12 sheets created one for each month, with the same headers as in the dump.

The two tricky parts:
1. The data in the dump is not sorted by railcar number, but the results in the monthly sheets need to be.
2. I don't believe LOOKUPS will work because rows in the dump repeat railcar numbers because of the multiple customers, and each of those rows has to be brought over to the monthly sheets, sorted and subtotaled by railcar number.

Finally, every week or so, I'm going to want to drop a new data dump in the dump sheet and need the monthly sheets to update dynamically. The new dump won't simply be rows added on to the same data as before, all the rows could be different. If this is solved most easily with a macro (i.e. drop the new data in the dump sheet, press a macro button and it populates the monthly sheets) I'm fine with that, but would need help with that code for sure!


Thanks to anyone who can help.
