Instead of spending hours trying to solve this problem here is what you need to do.

Run the following script to delete the order from the SOP work files.

delete SOP10100 where SOPNUMBE = ’44735′
delete SOP10101 where SOPNUMBE = ’44735′
delete SOP10102 where SOPNUMBE = ’44735′
delete SOP10103 where SOPNUMBE = ’44735′
delete SOP10104 where SOPNUMBE = ’44735′
delete SOP10105 where SOPNUMBE = ’44735′
delete SOP10106 where SOPNUMBE = ’44735′
delete SOP10107 where SOPNUMBE = ’44735′

Run Check Links on the Sales Work File.  Click on the MS Dynamics GP button, then Maintenance – Check Links. Click the drop down for Series Sales, then insert the Sales Work file and OK.

Re-enter the sales order.
