I want to change a string (sku) like this:
sku P1011-12-1010-202 is supposed to become P1011-12-1010
this is easily solved with node “string manipulation”: substr ($ sku $, 0, 13)
the problem is, that there are also values that are only 12 digits, e.g.
the values to be removed are always inclusive of the third “-” below
There are also different variants here, eg.
So I only need the value until the third block:
Has anyone got an idea?
