Parameters

Introduction	Parameters allow to change values and settings of TIS Projects (general parameters) and of operators (parameters of operators) from outside of the project (e.g., TIS Board) and for several operators at once. Parameters are project-specific, i.e., the scope of a parameter is the project in which it is defined. A parameter from one project is not visible to other projects (however, values can be shared by several projects via TIS Tables).
What kinds of parameters are there?	There are two types of parameters General parameters (e.g., a text or a number to be entered) Parameters of operators (e.g., scaling intervals that can be picked out of a list)
What are parameters good for? example:	General Parameters General parameters are of one of the primitive data types available in TIS. They allow for user input via the TIS Board, e.g., using the TIS Board - Recalculate 3.0 operator (including a caption and a helptext) to define a time range to be used in Forecasting (e.g., see Regression analysis seasonal 6.0), to enter a name, or to enter a value. Their values can be used (with varying syntax) in different operators, e.g., for the Filter on columns 1.1 operator to dynamically change the filter (using " around the parameter name), for the Read TIS table 5.0 and Write TIS table 3.0 operators, and for the Editable Grid (TIS Board - Read editable data table 5.0, TIS Board - Generate editable data table 4.0) by using a parameter in the path or in table names (using ' instead of " around the parameter name), i.e., to use dynamic paths or table names (e.g., different for each user) for the Importing data from SQL sources 3.1 operator to parametrize a query. Here, the parameter name is enclosed by ' and contained in TISParSQL, e.g., the Parameter ParameterMaxvalue can be used like this: `SELECT * FROM TABLE WHERE ´value < #XI.TISParSQL('ParameterMaxvalue')# as VAR1` accessed via get and set by the Formula operator (row-by-row) (4.0) = Formeloperator e.g. with XIH.SetParam("Super parameter") or XIH.GetParam("Super parameter") to be used and changed by a formula (with " around the parameter name). Parameters for operation settings These parameters refer to an operation setting, e.g., the intervals for scaling. They can be made available in the TIS Board by the Controller Portlet. This way operation settings can be changed from the TIS Board, the range of available options can be limited (e.g. users can select days, week, months,..., but not minutes, as scaling intervals), and settings of several operations within a project can be changed together, allowing a more consistent use and an easier interface.
How to change values of parameters?	Parameter values can be changed in two ways: From the TIS Board using the Controller Portlet, and by the Formula Operator via the function XIH.SetParam (see Formula operator: XIH Helper Functions)
Drop Down	Some value types produce specific interfaces (e.g. for date time) You may restrict the possible values or only allow for some values (e.g. texts in a drop-down menu)
Please note	Text parameters must not be longer than 4000 characters.
Python	The Python Scripting operator provides information on all parameters
