This disclosure describes techniques of validating data that a user enters into an enterprise system for storage within a multidimensional data cube. The data cube includes one or more data hyperplanes associated with members of a dimension having cells that contain data. In addition, the data cube includes a validation rule hyperplane of the dimension. Cells in the validation rule hyperplane contain data that indicate whether data in corresponding cells of the data hyperplanes comply with a validation rule. In accordance with these techniques, data in the cells of the data hyperplanes may be submitted if the data in the cells of the validation results hyperplane indicate that data contained in corresponding cells of the data hyperplanes complies with the validation rule.
