Custom Field Mapping

I did a cusomization on the Part Maint so that Part.Character01 can list Manufacturer.Name so that I can store that value into Part.Character01.

The value is being stored in Part.Char01 based on the BAQ.

I went into Custom Field Map so that QuoteMtl.Character10 (target) = Part.Character01 (source). When I do a quote and add material, I enter the PartNum, but QuoteMtl.Character10 does not populate.

Should their be some other programming that needs to be done? Eventually I would want this value to go to the ECO Mtl / Part Mtl and Job Mtl as well.

TIA.
