Recipe

Step	Screenshots	Why?
Open integration flow in read mode		Simulation is available in the read-mode of integration flow.
Switch on simulation mode		Enables the simulation tool bar to run simulation or clear simulation.
Define start point		Click on the connector line where you need to define the start of your simulation. In our scenario, it will be after start timer event.
Define end point		Click on the connector where you need to define the end of your simulation. Here, it will be before End Message.
Provide an input		To start simulation, message input is required. Click start point to open the simulation input dialog.Enter the input payload in the body.
Simulate response from Datastore Select Operation		Click Add Simulation Response speed button would appear to enter the response Datastore Select Operation.
Read the value of Write Variable in Content Modifier		To simulate the value of Write Variable in the Exchange Property of Content Modifier.
Run Simulation		It is used to run the simulation once the start and end point have been defined.
Clear Simulation		It is used to remove all the simulation elements like start point, end point, message processing output for all the previously defined.

Add the Write variable after the Content Modifier1 and define the variable name "Timestamp". This variable can be read via the simulation feature.

Add the following properties in Content Modifier2

• "Update_Timestamp"
• "Payload".

Response payload from Select DataStore

Sample response from the Select Datastore flowstep.

Simulate the value of Write Variable

On the Content Modifier2, click on add Simulation Response. Click on add Variable and write the Variable name i.e "Timestamp"and input the following value.

Timestamp 2020-04-27 12:11:00

Run Simulation

The Simulation can be run once all input values are populated. On successful run of the simulation, the simulated value of Write Variable in Content Modifier2 can be read as a property in Trace Envelope.

To view the payload updated after simulation of the Datastore Select operation click of the message body of Trace Envelope of Content Modifer2.
