Calculated column not populating ID?

[Vipin Tyagi]

Hello,

I'm trying 2 scenarios .In the first scenario, I want to concatenate FirstName Column value to ID.I have a calculated column to do this.

ex-

Calculated Column=FirstName&ID

but it is not working.

another scenario is that I want to pupulate ID column value in other column that is actually a calculted column but I'm stuck that why it is not working?

Any help is appriciated!

Thanks!

The ID field doesn't work reliably in calculated columns.  You'll need to use a workflow to set those fields instead of calculated columns if you want them to include the ID value.
