2 Question about lot controlled items

Hi to all

I have 2 question about lot controlled ítems.

1. First question is about how to properly create a lot by hand.

- In XE we were used to got Item Branch => Location revision and then add there the lot / location record, that did not create the lot master, only the location, but in the first transaction to that location the lot master was automatically created

- Now on 9.1 If we only create the location from location revision, then when we try to make the first transaction to that location the system gives an error about missing lot master, and if we only setup the lot master, the system is not adding the lot / location record in F41021 so we are not allowed to pre assign this lot / location to a work order part list (as an example),
