The short answer is no. However, you may be in luck because you CAN change the period end dates (in the Sales History tab of Profile). Changing the period end dates doesn't recalculate the figures, though, but (this part I am not 100% sure of) as long as your first and second 6/30 buckets are all zero, then you can change them to 7/31 and 8/31 right now, and you should be OK. Just don't do another period end until September. The June, July and August activity will just flow into the proper buckets.

If I am wrong about this, then there is a program in the ACCPAC Plus world called Inventory Tools which CAN recalculate the figures in the buckets as long as you haven't purged your IC History transaction file. If you don't own that program, you can send your IC data to someone who does, like me, and they can do the recalculation for you quite easily.
