I am using Pastel Xpress 14

Is there a way to "remove" allocations made in "match open item" for the customers ?

i have ran the "auto match" which keeps matching over 1.2 m to this client's one invoice, thereby putting the invoice in a credit amount.

Is there a way to remove all the allocations for this financial year (for this particular client only) so that I can "re allocate" each payment?

( other than un-allocating manually, as there are thousands of invoices)
thank you
