We will start labelling raw materials with our own labels printed on Goods receipt.  

We do not do picking before manufacturing, and the operator can take any lot number and use it.  

When you manually enter lot number for components, you get the list up in the look up, and you select.  But what we want is the operator to put the curson the lot nr field and scan the lot number.  It does not work.  In the screen it fills in another lot number.

Any fix out there?

Second question: What Barcode formats should we use in such a case.  Odoo has established GS1 Barcode nomenclature.  But when I test scanning labels for qty with AI30 or Lot number with AI10 do not understand that this is a GS1 type code.  Any advice?
