I am now at the point where it has become necessary for me to utilize the approved vendor function in DBA.  I see that you can assign parts to a specific vendor or even a BOM based on different requirements.  I don’t want to have to assign each part to a vendor or a group of vendors as this could become a maintenance nightmare.  For instance; what if I have a vendor assigned to 1200 different electrical components and that vendor becomes unapproved for poor performance.  I would then have to change the vendor list for 1200 different components.  At least that is the way I understand how the system works.  Is there a way to tag vendors as being approved on a list without assigning them specific parts and the system alerting the user that the vendor is not on the approved vendor list if they were to try and use an unapproved vendor; depending on how the options are set in IN-B.  Because some parts are vendor specific I would still want to isolate certain parts to one or two very specific vendors.  
 

That said, it would be easy enough to add a "Black List" flag to the vendor master that would prohibit PO-A from using a vendor who was on Disapproved Status from QC if that would help.

I think the "black list" flag for vendors to prevent a PO entry would be extremely useful.  
 
May I also suggest adding AP-B Enter Vouchers?

An Approved Vendor list would be wonderful.  Are there any updates on this?  Currently we run a live Crystal Report but it includes MRO and non MRO vendors.  Ideally, two options, MRO or not and Approved or Not.
