A customer could call you and tell you that there is an issue with a product purchased from you, and you decide to trace that material down to the original lot. First, you would start with the sales order in question.
Open up the hover field for “Packed Sales Order Lines”. Click the lot referenced there.
Once there, click on one of the “From Lot” selections in the “Movement Line (To Lot)” hover field.
Once there, repeat the process.
Keep repeating the process.
Eventually, you’ll wind up with the “Received Purchase Order Lines” hover field with a value. Click the purchase order referenced.
Select the “Received Purchase Order Lines” hover field and you’ll see the lots in question. In our example, there are two lots that went into the production of the higher level lot.
