Correlating and mapping original orders with new orders for adjusting long running order management fulfillment processes

A computer-implemented method for mapping and correlating a new order object with an original order object for a distributed order orchestration system, the computer-implemented method comprising:

• selecting a new order header object and an original order header object that share a source order number;
• selecting one or more new order line objects based on the new order header object;
• selecting one or more original order line objects based on the original order header object;
• comparing the one or more new order line objects and the one or more original order line objects;
• and
• where a new order line object and an original order line object match, setting a reference identity of the new order line object to an identity of an original order line object.

An orchestration system, comprising:

• a processor;
• a decomposition module configured to select a new order header object and an original order header object that share a source order number,
• wherein the decomposition module is further configured to select one or more new order line objects based on the new order header object,
• wherein the decomposition module is further configured to select one or more original order line objects based on the original order header object,
• wherein the decomposition module is further configured to compare the one or more new order line objects and the one or more original order line objects, and
• wherein, where a new order line object and an original order line object match, the decomposition module is further configured to set a reference identity of the new order line object to an identity of an original order line object.
