Next to the "Extract quantities" button, a drop-down menu appears that can select the type of quantities table where the quantities extraction is to be carried out.

For example, if the quantity is to be extracted for a certification table, it should be noted that quantity extractions are not cumulative, but partial (the contents of the quantity in the "Assign items and quantity extraction" window are always dumped to the quantity tables). Therefore, this table provides a partial quantity in progress and not at source. In other words, this certification has not been closed. The same happens if the quantity is extracted for the completed job table.
