System and method of request processing in a distributed data processing network

A first electronic device including a communication interface for providing connection over a communication network, the first electronic device comprising a processor operationally connected with the communication interface, the first electronic device being connected with a second electronic device and a third electronic device, the second electronic device being at least a part of a second subsystem, the first electronic device being at least a part of a first subsystem, the third electronic device being at least a part of a third subsystem, the second subsystem, the third subsystem and the first subsystem being at least a part of a distributed data processing network, the first electronic device and the second electronic device having respectively a first subsystem identifier and a first subsystem identifier associated with them correspondingly, the processor of the first electronic device being configured such that the first electronic device may perform:

• receiving, by the first electronic device from the second electronic device, a request to be processed and a first version of a request identifier, the first version of a request identifier comprising:
• a unique invariable part of the request identifier and
• a second subsystem identifier;
• generating, by the first electronic device, a second version of the request identifier by including the first subsystem identifier into the first version of the request identifier;
• transmitting, by the first electronic device to the third electronic device, the request and the second version of the request identifier;
• receiving, by the first electronic device from the third electronic device, a demand to provide a request processing history;
• and,
• responsive to receiving the demand to provide the request history:
• obtaining, by the first electronic device, a most complete version of the request identifier;
• reading, by the first electronic device, subsystem identifiers from the most complete version of the request identifier, the subsystem identifiers comprising the first subsystem identifier and the second subsystem identifier;
• determining, by the first electronic device, the request processing history by
• retrieving, by the first electronic device from a first data storage of the first subsystem, information about processing of the request by the first electronic device, and
• retrieving, by the first electronic device from a second data storage of the second subsystem, information about processing of the request by the second electronic device;
• and
• transmitting, by the first electronic device, the request processing history from the first electronic device to the third electronic device.
