Item classes separated by Legal Entity or Master Organization

Summary:

The business requires that Item Classes be assigned by Legal Entity

Content:

Currently the business has three legal entities, which require three universes of items. By having three Master Organizations, when an Item is created in Master 'A', the numbering sequence configured in the Item Class is for example: ITEM-1001

Now, if I create an item in another Item Master, for example in Master 'B', instead of creating it with the number ITEM-1001, what the system does is jump to the next sequence, ITEM-1002

This is a problem, since it requires the sequential to be independent per Master Organization.
