# Update Linked Calculations

> How a change at the source flows through linked calculations, and how to check them with Member Schedule.

Load linking removes manual reaction transfer. If the column changes (self-weight or section), you do not need to re-enter footing loads by hand. Updates stay linked in real time, which reduces error risk compared to copying values between calcs.

When something changes upstream, linked calcs update together.

* Example: on the deck joist, increase dead load (for example a planter scenario at 25 psf DL). Bending, shear, and bearing on the joist update immediately.
* Gear icons appear on downstream linked calculations so you know the chain may need a look.
* Open the deck beam and you might see a limit state go over, for example about 105% bending, while the column can still pass and the pole footing updates embedment and governing checks.
* With many beams or linked members, use Member Schedule to see which designs pass or fail without opening every calc. Fix the source and let load linking propagate.

<Note>
  One video covers the whole path from beam to column to footing, including live updates. This article covers the live updates and Member Schedule.
