}Something wrong here?
A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.
- A row from my list should not reach this flow
- This flow is not that chemical
- The compartment or the unit is wrong
- One of these characterisation factors cannot be this substance's
You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
