I'm having a hard time working with Altium's BOM management - here's my issue: I'm using general components like the shown 0402 capacitor part used in hundreds of places across the schematic. In these, there are issues with individual parameters (incomplete description, etc) on some of these parts. Ideally I'd like to group these parts together and update their parameters together, because it would literally take a week of copying and pasting to do this one by one with the schematic sheet.
The ActiveBOM seems like a good way to organize this, but I'm running into problems. I cannot seem to update any of the parameters in the parts listed without finding each one in the schematic. In the screenshot shown below, some of the descriptions of the same type of part are incomplete and show up as different parts entirely, despite being grouped by part number.
I clearly am working in a way that Altium has not intended. Can anybody point me in the right direction for cleaning up my BOM?
