The invention provides a method for producing correlation information of table data, comprising the following steps of: S102, defining dimensions occurring in a table; S104, determining a dimension to which each table head unit of the table belongs according to the defined dimensions; step 106, determining dimension information of each data unit according to a corresponding relation of each data unit and each table head unit of the table; and S108, establishing a relation information table according to data of each data unit and the corresponding dimension information thereof. The business data processed by the method are simple to define various data calculation rules, thereby simplifying a complex formula difining process in budgeting. The invention also provides a system for producing the correlation information of the table data.
