Is condition record configuration required for PPF in SAP EWM

Hi,

Could anyone please explain to me about the use of Condition Technique in PPF.

Is the condition record necessary for every action we define in the Action Profile ?
In which case we define condition record configuration and in which we don't ?

Like, if i want to use "Print Unloading Instruction for Inbound Delivery (action : /SCWM/PDI_01_UNLOAD_LIST_PRINT)" then do I need to configure the condition records for procedure 0DDNP or it can work without that as well ?
