Move Order task is not allocating on-hand in sequence

Dear All,

I have created a move order with item X having 100 EA quantities.

I have 3 locator having same item.

Locator A = 200 EA

Locator B = 300 EA

Locator C = 250 EA

But when I am allocating the move order, it is allocating randomly.

for example:

30 from Locator A

30 from Locator B

40 from Locator C.

But I want to pick from a single locator.

Kindly help me to solve the issue.

Best Regards,

Tushar
