Topic:   Why are there item numbers?

What is the point of displaying item numbers when they get re-ordered when editing the assembly? Drawings and procedures can no longer acurately reference Item Numbers.

Typically, reference designators (placed in the "Reference/Pos" column of a MiniMRP BOM) are used by drawings and procedures to identify individual items in a assembly.

That Item umber is more of a sequence number. When editing an assembly you can move items up or down the list and when the BOM is produced the items are in that sequence.

But it's quite obvious that Item #1 when editing a sub assembly can't be #1 when that sub assembly appears in the middle of a multi-level BOM.

Also, what about a common items that appears in many different products. You'd probably want the same drawing to refer to that item wherever it appears in any product.

So you couldn't reliably point an external document to an Item Number in a BOM.

But you can point the item to the external document.

Go to 'Components' > 'All Components'.
Double click any item to open the item detail window.
Across the middle of the window you see a row of tabs.
One of the tabs is "Links"

Open the links tab. Here you can create links to external documents, drawings, PDFs etc and even remote web pages such as manufacturer's data sheet on their website.

Now go back to a BOM that contains that item. You should now see a column containing a clickable link icon. Click that icon to open the linked document or webpage.

You now don't need any reference numbers to connect the item to the drawing. When you're looking at the All Components list or any BOM containing that item you'll see that clickable link to give you quick access to the drawing or whatever the link is point to.

Only 'gotcha' is if you're sharing the database with multiple users then the external document needs to be in the same place for all users. Remote web pages aren't a problem but if you make a link to a document on 'your' desktop then other users wouldn't find the document when they click that icon. So put the documents in a common location where the link works for all users such as
\SERVERNAMEDRAWINGSetc or a mapped drive letter to a shared network folder.
