Which serial control works for assets with serials if item has no serial control?

What serial control should be used—Dynamic entry, Predefined, or No serial control—when the same item is used for multiple assets, and serial numbers are defined at the asset level?

Our asset numbers are alphabetic (e.g., EAM), but serial numbers like W1001 are maintained.

• If we set serial control as Dynamic entry at inventory receipt, will it override the asset number?
• What happens if serial control is set as Predefined or No serial control?
• Can we still define and save a serial number in Manage Assets if the item has No serial control?

Urgent clarification is needed. Kindly advise.
