Setup Lot Number At Organization Level

Dear MOSC,

I have requirement to generate running number for lot at organization level. I already setup the number at organization parameter, but still the result doesn't come up with what i expected

This is the requirement:

Org: DK-1

Item: All Item

I want to generate lot number: DK1-000001 and keep running until DK1-999999

Org: DK-2

Item: All Item

I want to generate lot number: DK2-000001 and keep running until DK2-999999

My configuration at organization parameter:

Lot Control Uniqueness: None

Generation: At Organization Level

=== Lot Name Generation ===

Zero Pad Suffix : Y

Prefix: DK1-

Total Length: 10

=== Child Lot Control ===
