Back  RFI # 1312: 999/CTX - Business Unit

Formal vs. Informal Help Informal Formal


Malene Davis


The CTX-Business Unit should be returned when the error in the IK3 loop is within a business unit. There is no definition of "Business Unit" and we are wondering what the definition is.

For example, the 270 has a business unit identifier of TRN02, so does that mean the if the error occurs after the TRN segment, it would be considered within the business unit? Using this example, if there is a dependent loop and the TRN segment is in the dependent loop, and a validation error occurs at the provider level, would this CTX be returned?
