After picking, the slot content must be transferred to a buffer (if the contents fits). If the slot content does not fit the buffer, the content can only be placed on a stack.
If goods are picked in multiple zones all goods are being gathered on a stack. The stack is the final location before the shipment can be completed. This is visible on the packing screen.
Every buffer will end up at a packing table. The packer will scan each buffer. Depending on the number of buffers used to pick the order, Clougistic will guide the packer:
only 1 buffer used to complete the order
It is possible to make a shipment.
buffer is one of more to complete the order but not the last one in the process
It's not possible to make a shipment. Put the buffer on stack. If there is already a stack in use for this order, it's possible to add the content of the buffer to the used stack.
buffer is one of more to complete the order and the last one in the process
It's possible to make a shipment. The goods from stack and contents from the current buffer should be added to the shipment.
Once a shipment is created the stack and buffer can be reused in the proces.
