Description of the message

For guidance, the following principles serve to remove ambiguity in the application of an EDI Purchase Order Change Request.

The content of a Purchase Order Change Request is assumed to affect:

The modification of a previous Purchase Order as requested by the buyer,

The modification of a previous Purchase Order in confirmation or response to the amendments proposed by the seller in a Purchase Order Response.

A change may not be requested on:

the Purchase Order number,

the identification of buyer and seller,

the line item number.

These changes may only be made by cancelling the previous Purchase Order and re-ordering.

The only data segments and data elements required in the Purchase Order Change Request are those:

Marked in the branching diagram of the Purchase Order as mandatory, including the two repetitions of NAD identifying the buyer and the seller, and one repetition of the RFF segment (group 1) to identify the order being changed.

Changing the previous instructions, adding clarification or any other terms, in the detail section. If segments below LIN are changed then all segments below LIN must be re-transmitted. It is not an error to re-transmit unchanged data.
