The Execute Condition can be of types - None, Static Value or Read from Message.Select the None option to specify that there is no execution condition for the business process.Select the Static Value option to specify the actual condition for execution.Select the Read from Message option to read the condition from the Message Map. This ensures that the business process does not have to be modified for every change. Click to select the process specific message from the XPath editor.
Note:

• Ensure that the dynamic condition which is taken from the Message Map does not start with a slash.
  
• If a message contains an XPath expression, then the XPath need not be in single quotes. For example, if the message is /mycondition and it contains an expression as follows: GetEmployeeOutput/GetEmployeeResponse/tuple/old/Employees/City = "London", the XPath will be as follows: GetEmployeeOutput/GetEmployeeResponse/tuple/old/Employees/City = "London".
• All XPath expressions are supported in Message Map 'Expression'.
  Note: In a Delay Event, the Execute Condition option can be used instead of the Decision construct.
  You can view a small Decision () icon at the bottom left of the construct to indicate that the Delay Event includes a condition to be executed.
