Abstract
A method and system for determining currency of data in a data processing system. The processing steps along a dependency chain used to populate a data reporting program are back tracked recursively through each processing step until a first originating set of processing steps are reached. The currency of each data source for the programs is identified and it is determined whether the program has run since that time. If any one of the sources for the program of the processing step is more recent than a last run time of the program associated with the processing step, the program is re-run and outputs updated. The same process is executed moving forward along the dependency chain, to each other processing step.
