Creates a link between the variables in the pipeline. Links can be created between variables in Pipeline In and Service In, or between Service Out and Pipeline Out. In a MAP step, links can be created between variables in Pipeline In and Transformers, or between Transformers and Pipeline Out. To link a variable from one stage to another, select the two variables, and then click the link button. This button is not available unless you select two variables that can be linked successfully.

Creates a ForEach mapping between the array variables in the pipeline. ForEach mapping can be created only between array variables. To create a ForEach mapping, select the two variables, and then click the ForEach mapping button. This button is not available unless you select two array variables of the same data type.

Assigns a value to the selected variable in the Service In or Pipeline Out stage.

Drops the selected variable from the pipeline. You may remove a variable from the Pipeline In or Pipeline Out stage. When you drop a variable, that variable is removed permanently from the pipeline and is not available to subsequent services in the flow.

Creates a link to or from the value at a specific position in an array variable. This button is available only when at least one of the variables connected by a link is an array variable.

Adds a new variable to the selected stage in the pipeline. This is a useful way to create a variable that is used by a service in a flow (that is, taken as input or produced as output), but was omitted from the input/output signature.

Moves the selected variable up one position. If the selected variable cannot be moved up from its current position, this button is not available. (Try promoting or demoting it first.)

Moves the selected variable down one position. If the selected variable cannot be moved down from its current position, this button is not available. (Try promoting or demoting it first.)

Promotes the selected variable one position to the left. If the variable cannot be shifted left from its current position, this button is not available.

Demotes the selected variable one position to the right. If the variable cannot be shifted right from its current position, this button is not available.

Inserts a service for use as a transformer in a MAP step. This feature is only available when a MAP step is selected in the editor.

Enables the Pipeline In, Pipeline Out, Service In, Service Out, and Transformers columns to be scrolled horizontally and vertically independent each other. Independent scrolling is especially useful when mapping a large amount of data in the Pipeline view.
