I am working on an AR Import for Sage 300 in the actual Accounts Receivable Module; I am having trouble with the taxes calculating properly. If I manually enter the invoice I put the total in the top line and the subtotal below as taxable to the right tax group and hit calculate taxes and then save. When I try import many invoices and set it up to do that it says the 'sum of my distributions do not equal the invoice amount'. But it isn't giving me the screen to hit that calculate taxes it just errors out the import. Am I missing something? I have been told that I would have to manually calculate the tax but not to the tax groups we have set up but to each tax id and add a distribution line for each id needed in the import. This is for service work and I could have 100's of invoices to potential import in a week and that seems like more work than manually entering them so I am hopeful there is a way around this and my limited knowledge of Sage 300 is the problem. 

Below is a list of work arounds I have tried unsuccessfully.

I tried to enter the tax line to a different distribution than '9' for tax, like 7 for other or 8 for add-on, but the tax g/l in the spreadsheet makes the import error 'Control account required for accrual credit. (671)' Maybe there is something I can add to my spreadsheet to get past that error?

I am not sure if there is maybe a way to transfer the tax line to different tax ids once in the system other than voiding in the invoice and resubmitting to the right tax group. If this is possible somehow I could maybe work this out as well.

I would greatly appreciate any ideas or work arounds out there.
