- Go to Materials view
- Edit a material
- In General tab, try to maintain quantity conversion
- The error message appears: Conversion between A and B not valid; conversion to B already exists
The error message is raised because you try to maintain cyclic quantity conversions. If you have maintained one conversion between A and B and the other conversion between A and C. The quantity conversion between B and C is not needed because this can already be calculated by other two conversions.
