We are receiving error on billing rule after creating new tenant by restoring snapshopt of the business accounts and settings of the previous. We dont have any problems encountered when time activities are released but when attempted to run proforma billing, this error keeps on showing.
Failed to calculate the amount using the 1 step of the TM billing rule. Line Amount Formula: =[PMTran.BillableQty]*@Price Error: Object reference not set to an instance of an object.

Thank you.
