Information on retrieving data from Order Entry into Softrak Sales Analysis is on page 1-7 of the Sales Analysis manual.

When you print and clear the Invoice/Credit note audit lists in OE, the information is transferred to temporary files that Sales Analysis retrieves from. The 2 files are
SRSHIPTX and SRCRNTTX.

I do not believe that Order History is updated in the same manner. You may wish to confirm this with Softline.
