How to manage ontime and unpunctual maintenance order execution in SAP PM

Hello community,

I have created a set of maintenance plans in SAP PM and i want to define a one week execution margin for the maintenance orders (ex: if an order is created on monday, i have untill next monday to execute it and still appear ontime in the execution report).

i have tried to set up the tolerance (+) in the maintenace plan scheduling parameters but it seems it didn't work. now all the orders which are executed one day after the order creation are reported unpunctual.

Please can someone help me with this.

Thank you all.
