IMDCalculationFormulaDelimiter.Delimiter

Syntax

Delimiter: MDCalculationFormulaDelimiter;

Description

The Delimiter property determines a delimiter used as a formula operand.

Example

Executing the example requires that the repository contains multidimensional calculation on DB server with the MDCalc_1 identifier.

After executing the example the formula is set for the specified data consumer element. The value by coordinate in the data consumer is calculated by the formula: value by coordinate in the source is multiplied by 3.14. The value by the second coordinate in the data consumer is calculated by the same formula, but coordinate value in the data source is taken by one day shift according to calendar dimension.
