Science & Industry

What error is it giving you when you try? Are you delivering a job when your are manufacturing from a BPC or creating a BPC, as if it's creating a BPC, you'll need scientific networking. If you're unsure what you need, click the active job, hover over the area that says how many jobs you have/control range and it should pop up with your skills so you can see what ones are affecting it, like this.

So you are delivering a copy job, not a production job?

In that case, it's driven by Scientific Networking instead as Lucas said.

For trade - I can't remember all the skill names, but there is a skill that governs remotely placing buy orders, then another skill that governs how wide those buy orders can be. For instance if I am in Balle (2j from Dodixie) and try to place a buy order in Dodixie I need the former skill but the order is limited to station-only. The second skill lets me place a 10j wide order centred in Dodixie while I am docked in Balle.
