Availability check
According to the documentation the MRP type and the item category determine the requirement type.
MRP Type Z1 and item Category ZBVN use Requirement type 031
The scope of the availability check is determined by the checking group and checking rule
The checking group is 01 - Daily requirements but I don't know which checking rule is determined by the system. Documentation says that it is determined automatically by the system. Which one would be used by cash sales order without a delivery process?
Can you have a look at my config and see if I'm missing something?
