Using "Computed Fields" to fix mismatch in Data Sources

In the BAS boat registry, the previous difference between the boat winter storage and the summer dock spot has been removed for some strange reason.
So, we had to make a fix that “creates” fake variables according to a formula.

In this case: the variable "vinterplatser" is defined as string_part(v.plats, string_part_index(v.omradeskategori, "Vinterområde"))

Sadly, this is quite complicated. Please contact your Blippa partner to get assistance.
