Add-on cost codes

ASC X12 provides standard set of codes for identifying add on charges or allowances. Customers define their own codes. Data substitution records provide a cross-reference between the X12 standard codes and your proprietary codes to identify add on charges (AOC). You must work with your trading partners to identify the AOC codes that they use and their meaning to cross-reference them with your AOC codes.

Note: If an AOC Code cross-reference lookup does not return a value, then the original code from SAC02 is mapped to the Match Invoice interface.
