Backorder Process - Filter type

Hi Gurius,

I have created one Filter Tyoe "FILTER" and one Sort Profile "ZSORT" inn Backoder Process.

Under this sort, we have 5 Sales Order type:

Sort Item 1: ZSO1

Sort Item 2: ZSO2

Sort Item 3: ZSO3

Sort Item 4: ZSO4

Sort Item 5: ZSO5

So, I'd like that onlly Sales Order Type ZSO4 never loos Confimed Quantity even though ZSO3, ZSO2 and ZSO!1 has high priority under the sort.

ZSO1, ZSO2,ZSO4,ZSO5,could have a normal behavior.

It is possible?

Regards

Abate
