Hi,
Sorry for the late reply. Not sure I understood it correctly. If you are using the “Default formula”, you can change the parameter there and product prices will change accordingly. For example, if you have x*1.05 formula, then after you change the margin (i.e. 1.05) product prices will be updated. Could you please try to explain it to me to once again (if possible maybe give an example of how this should work)?
