Abstract: A non-transitory computer-readable storage media storing program instructions which, when executed by processor(s), cause the processor(s) to perform: receiving a workflow for processing a period, the workflow comprising steps for processing data items related to the period, processing the data items according to the workflow to generate an output, capturing, during processing, metadata about the output, storing the output, the workflow, the data items, and the metadata in a database, receiving a modification to one or more of the data items and storing the modification, resulting in modified data items, receiving, during an open period, a request to reprocess the period using the modified data items, in response to the request, processing, according to the workflow and the metadata, the modified data items to generate modified output, determining a difference between the output and the modified output, carrying the difference over to the open period.
