Whilst investigating the current issue I have with inventory and portion sizes, I have discovered that I'am unable to select fraction multipliers in portions. I get a red box then an error message as detailed in the attached errorlog2.txt, the screenshot shows that the system allows me to enter a fraction multiplier and does not stop me saving.
I have a scenario where I need a fraction multiplier so this looks like another case of having to create a new product.
Pepsi is sold in two glass sizes, one approx 330ml and the other 500ml, so a 1.5 multiplier is required to calculate inventory.
Perhaps someone could confirm if fraction multipliers should be allowed, otherwise we are always assuming that other portion sizes have to be double, triple or quadruple of the original normal portion ?
