When a tank of raw material is used up and the weight falls to zero (or below), ColorPoint Manager highlights the batch in red. This is a hint to the user to check the status of the stock and if appropriate, to finish the batch to prevent it from being used again.
Finishing the batch also keeps the Stock Overview tidy, showing only batches that are actually useful. To finish a batch, or a selection of batches, select the items from the list and right-click. Choose Finish from the contextual menu that opens.
If the Finish menu item is greyed out, this means there is a batch in your selection that is still allocated to a dispense valve. In this case, the normal refill procedure should be carried out first before finishing the batch.
