Hi Lalitha,

It is possible.

In the Trigger that you are going to create to start the workflow when a record gets created or updated, you specify some conditions, based on the entry log of the action that has been made.

For example if I create a record in the UI, I'm going to have something like that:

<UpdateRecord>
    <Date>2012-04-13 12:54:00</Date>
    <Updated By>Vincent</Updated By>
    <Action> CREATE</Action>
    <Id>1</Id>
    <Entity>Customer</Entity>
...
</UpdateRecord>

The tag names are not corrects, but you will be able to see the fields when you select the Update Record entity.

So one of this tag actually tells where the update/create comes from. I think the value is WebUI if it was done in the UI, workflow if done from a workflow... And another value if done through a job.

You should take a look at the journal and see what gets entered when you create a record from the UI or from a job.

But basically you can create 2 triggers, one that has the condition "From=WebUI", another "From=DIJob", and you can start a workflow or the other depending on the update source.

Hope that helps!
