# Defining the Details for the Data Source

## Procedure

On the Data Source tab page, you can make assignments between the fields of the data source and the entry table of a function or procedure, and create filters and calculations.

- Choose the Data Source tab.
- If you data source is an InfoProvider, you can specify a fixed or variable date. If required, you can recreate the date variable directly. More information: Defining Variables
- Use the mouse to drag the arrows between the fields in the data source and the entry table of the function or procedure, or choose the relevant fields (in a projection or a generated procedure for example).
- By double-clicking in the Filter column, you can define a filter with variable or fixed values for the corresponding InfoObject.
- If your data source is an InfoProvider, and you have key figures with currencies or units, you can double-click on the corresponding unit or currrency symbol to specify a quantity conversion or currency translation type. When the analysis process runs, the unit or currencies are then processed accordingly.
- By choosing in an InfoObject's context menu, you can create a new formula. To begin with, enter a description and a referenced InfoObject or a data element. When creating the formula, you can make use of predefined functions in the formula editor.
- You have to model date calculations (such as sy-date + 1) with formula ADD_DAYS_TO_DATE, both for internal and external display.
