Welcome to the Community, @ezz-sarieh. I'm here to help.

To provide the best response, I'd like to gain some insight into your situation. Are you trying to record partial inventory received or are you recording a purchase order? Once I know this information, I'll be able to get you back to business in no time.

In the meantime, I recommend checking out: Apply a purchase order to a vendor transaction

Please touch base with us here if there's anything else you need, I'm determined to ensure your success. I look forward to hearing from you again.
