BCVariable

VariableIcon Description

Nodes of this type are used inside Attributes node controls. They can be used to place variables referencing a Business Component in the panel's form.

BCVariable nodes belonging to an Attributes node are assumed to belong to the same Business Component variable in the transaction. Because of this, the developer must specify the Transaction that should be used in the "Business Component" property located in the Attributes node. See the example below for more details.

As you can see in the example, a variable is generated for the BC. The variable's name is "<BusinessComponentName>_BC".
