The coded field on a hold, rejection, return or credit that says why it happened, and the input to cause attribution.
A reason code is the value a system records against a failed row: why a customs entry was held, a claim rejected, a delivery refused, a credit issued. Codes are specific to each system and rarely mean what a reader assumes, so the mapping from code to cause is written once per source and kept with the data. Rows with no reason code are counted as their own row, never dropped and never guessed.
The coded field a system records against a hold, rejection, return or credit. A mapping from each code to a cause is written once per source system and kept with the data; rows with no code are counted as their own row.
A returns file has fourteen codes. Mapped, they reduce to four causes: wrong item picked, damaged in transit, ordered in error by the customer, and quality. Six percent of rows have no code.
Codes read by their labels. Other is the most used code in most systems and means the field was mandatory.
