An information processing apparatus hosting a multidimensional database software application receives a batch of data values to be updated from an external client computing apparatus running a data entry application. The multidimensional database software application identifies a second batch of data values previously stored that have been flagged during prior updates to remain unchanged. The multidimensional database software application then combines these two batches of data values and calculates final data updates. The calculation method ensures that the final data changes committed to the database represent a best, if not exact, match to both the first batch of data values to be updated as well as the second batch of existing data values flagged to remain unchanged.
