“AWB failure” can refer to two very different scenarios depending on whether you mean Air Waybill (Logistics/Shipping) or Auto White Balance (Camera/Imaging). 1. Air Waybill (Logistics) Fails

An Air Waybill (AWB) fails when it cannot be used for shipping or causes delays in transporting goods. Key failures include:

Reuse of AWB Numbers: AWB numbers are typically blocked for 45 days upon re-stocking to prevent airline issues. Reusing a number too soon—generally within less than a year of the previous shipment—causes a “number already used” error.

Expired Numbers: Pre-assigned AWB numbers often expire 365 days after issuance, becoming invalid for use.

Missing Consolidation Indicator: If a House AWB (HAWB) is being used, the Master AWB must be designated as a consolidation (“M”). Failure to do this leads to rejections like “HOUSE INVALID AWB NOT DEFINED AS MASTER”.

Invalid Association: If a number is entered randomly or is not properly associated with the shipper’s organization in the system, it will be rejected.

Incorrect Info/Customs Delays: Inaccurate details (e.g., wrong weight, missing documentation) can cause customs delays or cargo rejection, disrupting the entire chain. 2. Auto White Balance (Imaging) Fails

AWB failure in photography or image processing (e.g., TDA4VM) occurs when the camera cannot accurately interpret the light source, resulting in poor color accuracy.

Dark Environments (Low Lux): AWB frequently fails in low-light conditions (e.g., below 5 lux), often producing a green or unnatural color cast.

Poor Calibration: If the AWB plugin or sensor calibration is improperly set, the camera will fail to identify the correct color temperature, especially in challenging environments.

Complex Lighting: Mixed lighting (e.g., warm tungsten indoors + blue moonlight) can confuse the algorithm, leading to an incorrect, unnatural color balance.
