Lot number is not taking locationwise

Thanks Adam,

I have Six Locations.

A , B, C, D , E, F

So i defined the Six number series for Location wise Lot tracking.

I had given the relationship for six number series.

I created a purchase order and for Location B . i go to Item traking Line and run the function Assign Lot no , then system automatically

assigning the A location lot number series.

Here the problem is It does not show up the number series when run the function Assign lot no.

so how can i assign the lot no location wise

What do lot numbers have to do with locations? What if I create a lot in location A then transfer it to lcoation B?
