I have a query regarding Datacare V6.5A 990324

When an integrity check is run using datacare to check purchase
orders files I receive the error:

" Cannot open non existant file C:\DATA\ICIPOD'I.DAT" This file does
not exist in our Accpac data. However Inventory control checks out
with no errors.

This error has been apparant for at least 6 months and the system
continues to operate successfully. Also when I create a new set of
Purchase Order and inventory files the file is still not created.

The Accpac system manager also reports the same error.

We have PO v 6.1C 980128 and
INV Control v 6.5a 990809

Do you have any ideas whether this error is a fault of the integrity
checker or Accpac Plus or our data?
