Hi Sreenu,

Equipment is PM component No whenever you create a device in IS-U DM module automatically in background Equipment in PM created, When your Installing this device/ Eqipment system generate logical device No , which is MAPPED in ESTL table.

Can you please explain us with a list of reasons why the device may not have a logical device number?

If the device does not have a logical device number, is the device classed as unoccupied?

Hi Sreenu,

Your Correct, When your Technically Install the device system automatically generate the logical device no.

When you create the Device IQ01, check the status , it is AVAL, when you install the same the status automatically changed to ESTO / INST, at this movement the logical device no generates.
