How you deal with resistors and capacitors in Altium?

If you have a single resistor/capacitor, it is easy later to change values, etc, but how do you deal with the BoM later?

But, if you have different components, i think it is a nightmare!! there are so many!! with links, etc. And I think, you have the same problem here, because for a resistor, there are many supplier id's...

How do you manage all this?

We use multiple resistors, each with separate values in custom fields that we've added such as manufacturer info, etc. Takes time but in the long run it makes creating the BOM easy.

This means you can't readily just change the component value and you have to actually code the part.

Some people like to have the schematic fully specify everything, as Gustavo suggests. I preferred to keep the schematic simple, and manually edit the BOM to add supplier and part number information.

I used a BOM format that gathered all identical components together - one line might say "25 10K 1/4W resistor" - then I would add the supplier and part number to that line. If I had to change supplier, I only had one line to change, rather than all the parts on the schematic.

For small projects yes. But multiple projects where you want to reuse some elements this can become a bit of a nightmare. –  Gustavo Litovsky Sep 13 '13 at 17:13

@GustavoLitovsky: I suppose the method will depend on the work environment. Where I worked, I generally did the whole project, and rarely produced more than a dozen units of each design, so my method worked for me. In a larger company, with corporate-controlled purchasing and parts stocking, your method may be more appropriate. –  Peter Bennett Sep 13 '13 at 17:50

Single resistor for 0603, 0805, ... The comment field contains the article number from the ERP system and is entered manually. Yet, if you use a e.g. 0R resistor more often, you can simply Copy&Paste it in which case it will keep its fields.

The ERP also has a long text for that very part. So when the BOM is created, it will print out the long text as well.
