Activity description:

The Wait for SMS Activity can be used to wait for a number of SMSs for a particular time period, both of which can be set in the activity's properties. It can store SMSs (completely or partially) into specified variables. Depending on different property settings the activity will give different outputs.

Activity Properties:

The Wait for SMS activity has to be configured by specifying appropriate values for the different properties in the Activity Properties area. The Activity Properties can be accessed by clicking on the Activity Properties tool in the tool bar or by selecting the appropriate option from the right click menu for the Wait for SMS activity. The Activity Properties are organized under the following groups of related properties. The properties under each group are described in this topic.

Name & Description

The properties in the Name & Description group have been described below. You can use these properties to specify the name and description for the activity.

Configuration

The properties in the Configuration group have been described below. You can use these properties to configure the functionality of the activity.

Steps to set the Filter Expression property

Select an attribute from the first drop down list, then select the operator, type of value (Value, Variable, Content, XMLVariables), and the corresponding value for the property from the corresponding drop downs. Select "End" from the last drop down to complete the expression. If you are building a compound expression, you can select one of the logical operators to connect the different conditions that form the expression.

  3. Add the condition to the expression by clicking Add. This will display the expression in the text area.

  4. You can remove a condition already added to the expression by clicking Undo.

  5. You can also clear an existing expression if necessary by clicking Clear. This is useful if you want to clear large expressions in the text area in order to build a new expression.
