In Search I saw some discussions of this, but couldn't find the fix.
I have one PN that, when I do a PO line for it, the proper Conversion factor initially shows on the screen (so I believe the IN-B setup is correct), but when the cursor passes the Qty field, the factor changes to 1.  Same in both Classic (2/14/07 Update) and Evo. Then PO Receiving obviously screws up the Stocking quantities and cost.
I have plenty of other parts where it works just fine, lickety-split!
Is there a fix? or a repair?
 
Thanks
 
 
 

Kevin, thanks.  No, we don't use PO-H and it's not populated.  I did go in and start to enter a Vendor Price for the ill-behaved PN and the conversion factor showed correctly, and didn't change to 1 as I went thru the screen.  
 
I don't do much Maintain Database stuff, but is that where I need to go?  If I know the right file(s) and field I can handle it.
 
Still hoping someone knows what's wrong.
 
Thanks.

You found it, PO-H was the problem.  I edited the Quote to correct the factor and PO-A behaves correctly now.  Thank you, Kevin.
 
But ISTech, the underlying problem with PO-H needs to be fixed, please.
