PO Suggestions Error

We are running Vantage 5.1 and getting errors while running the
Generate Purchase Suggestions process. The error is:

**SugPoDtl already exists with Complany "MEI" SugNum 153.(132)

It pops up when it hit certain parts as it goes through the
generation process. The last time it was run, it came up 58 times
through out the process.

Anyone know why thisis happening? Anyone know how this can be fixed?
It has been sent to Vantage support but have gone over a week without
a solution already.

Thanks!

Erik
