A supplier is on a project within your company but given the current conjecture you request to end the project?
Here are the steps to follow.
Go to the My Projects tab. Right click in the first Option column of the project you wish to terminate and then click on Request to end the Purchase Order.
Please enter the required end date of the project and then choose a reason from the drop-down menu. You can add a message and click on Validate.
Suppliers can now accept or refuse your request for early termination and indicate the reason.
