When issuing a DO, if you want to speed up the process by skipping dispatch, you can enable a setting to immediately deduct the DO's issued quantity from the product's in-stock quantity.
The setting follows these steps:
Step 1:
Go to Basic Settings and choose App Settings.
Step 2:
Scroll down to Shipment Settings.
Now you will need to enable the function 'Exclude Issued Shipment quantity from Products in-stock quantity'
This function requires disabling partial dispatch and the staging warehouse, so you need to turn off both for the system to work properly.
Step 3:
Click SAVE in the top right corner.
