7. How to Extract Gas

Users with the Filling Manager role possess the exclusive capability of extracting gas. If a cylinder is in a defective state and completely filled, the Filling Manager has the authority to extract the gas from it.

To extract gas from a defective cylinder that is full, the user needs to follow these steps:

1. Go to the stock tab and select the 'Extract Gas' option.
2. Specify the product type by choosing it from the available options. In the drop-down menu for the product type, all the defective full cylinders within that specific container will be displayed.
3. The state of the cylinder will automatically appear as "full" since it needs to be full in order to extract the gas.
4. At this stage, the user should enter the quantity of cylinders that will be extracted for gas.

After the user clicks 'proceed,' a message will appear as a pop-up. By clicking 'confirm' on the pop-up, it signifies that the gas extraction process has been completed successfully. As a result, the state of the cylinder will be updated from 'full' to 'empty.'
