We created a 304 price change worksheet some months ago and ran it on all but one store. The further change was made to the HQ prices. The old worksheet was then run at a store which had been offline for some time. Running the worksheet appears to have altered the prices on the HQ database back to the values they had when the worksheet was initially created. We have run 'old' worksheets before, including price changes, and this has not happened before. Any ideas on why it's happened, and h ow to prevent it? Thanks
