VBT Movement Details
You must enter values in the Capacity Type and VBT Type fields in the To Vessel area before you create a new VBT. You can dynamically generate a new VBT if the To Vessel is a VBT.
You can add or remove barrels from the VBT, which increases or reduces the aggregated volume of the VBT and might change the summary attributes. If the barrels that are added to a VBT contain blends, then the two blend lots will be mixed according to the standard blending rules.
When you add a barrel to a VBT, the barrel is by default considered full, but you can empty the barrel as part of an operation. When you empty a barrel that belongs to a VBT, the barrel remains in the VBT with a quantity of zero and a barrel volume status of Empty. When you close an operation, the system updates location and rack for all barrels, including empty barrels. You can update the location and rack for the empty barrel. In this case, the system deletes the barrel from the From VBT details and adds it to the To VBT detail.
When you empty a barrel in an operation, the system displays the empty barrel in the VBT for the After lot. However, if you use the same VBT that includes an empty barrel in a subsequent operation, the system does not copy the empty barrel to the After lot for that VBT and operation.
You can refill empty barrels, but only if they are not associated with a new VBT.
