I have seen other errors that are similar in here but not this one specifically I think. When a user tries to update a specific part in Part Maintenance, we are getting the following message.

Business Layer Exception

Field references invalid value.

Exception caught in: Epicor.ServiceModel

Error Detail

Client Stack Trace 
==================

All they are trying to change is the Supplier, Lead Time, and Days of Supply.

My other question is, why is this happening, not just how to fix it. I want to know more about what is going on and why this is happening.

Check to make sure the method specified here exists and is approved

There is already a method that is in there. Just wish I could pin this one down. I am sure I will find it soon. Will keep this post updated when I get something figured out.

I’m concerned there may be something wrong with that alt method. If you clear the Primary Alternate Method box can you save the changes?

Once I clear it, yes I can change things in the part screen. I currently don’t know how to change anything with methods. I will be looking at how to do that today.
