A apparatus is provided for updating data within a business planning tool. The apparatus comprises a computer memory (22) arranged to store operational data in a plurality of line items (50), each line item (50) being arranged to represent operational data in data cells (52) occupying space in a plurality of dimensions (X, Y), and each line item (50) having data cells in a first dimension (Y) configured to represent the operational data in a at least one hierarchy level, and having data cells in a second dimension (X) arranged to represent the respective operational data over at least one time period. A processor (24) is arranged to partition each line item (50) into data blocks (60) comprising one or more data cells (52) by identifying and grouping data cells (52) which belong to a single hierarchy level within the first dimension (Y) and a single time period within the second dimension (X), to create a dependency graph having a node for each data block (60) and which represents the inter-dependency of the data blocks (60) and in which there are no internal dependencies within a data block; and to update the data blocks (60) based on the dependency graph when at least one data cell is changed. In this way, an efficient updating apparatus is achieved.
