One client has been having a sporadic issue where a vendor is entered into Vendor Maintenance, invoices are processed, and later they are not able to find the vendor in Vendor Maintenance.  The client is not using temporary vendors.  In fact, even if they were using temporary vendors, the last time the problem happened was in the middle of the month.  A new vendor was added on 4/20, and now the vendor is missing.  We checked DFDM...not there.  The vendor master file has NOT been rebuilt; thus, no records should have been removed due to be corrupt, etc.

I opened a case with Sage support, and they were not able to find any evidence of the records being deleted.

In the past when this problem occurs, we have re-entered the vendor into Vendor Maintenance.  Once this has been completed, the open invoices show up on the Invoices tab, etc.

We have not re-entered the vendor for this last instance, but the vendor invoice can be opened in Invoice History Inquiry.

This has been an on-going problem and has happened in versions 2014, 2015, and now in 2016 as well.

Any thoughts would be greatly appreciated.
