Part Time Phrase Inquiry

How can we remove a record from the Part Time Phrase Inquiry?
We have a record in PartDtl table with SourceFile= “PT” which we don’t know from where it came and we want to remove it.

What shall we do?

PT is an In Transit Transfer Order you should be able to use Receive Transfer Order in the destination Plant or unship from the sending Plant.

Thanks for the help.
