Bill of Material Transfer error

Hi experts,

I am working with BOM Transfer and I have one issue and one question:

- Error: In CG37 I can select a material and a plant but when I try to get the Hit Lists no results are available even though the material is linked to a specification and the plant is valid for that material. Any idea why? It says "No data found" even though the material exists related to the plant

Question: If I have a BOS of a material which Base Unit of Measurement in MM is UN (Unit) can I use the BOM Transfer functionality? The problem is that it is not in weigth or volume dimension. Any idea how to solve this?

Many thanks and regards,

Alberto
