How to define a placing strategy in a racking area. Step 02 In the column 'Flow% / Main adr.' you can define how many percent of the total flow you want in that particular rack. Please note that the total must add up to 100 %. If you want the same flow in all racks you can first just put 1 on each line, or right click and choose 'Equal percentage on all adresses', and then click on OK to go back to the 'Define adress areas' window. Then click 'Edit strategy' again to go back to the Edit strategy window.
