Frequently we get an error while we try qualifying a lead in PSA you get an error, “OrganizaionServiceFaultSyste,.ServiceModel.FaultException’1……………………..”
It also says, Parameter name: You must select a PriceList before Saving.
The solution to that issue is as per below.
We had to write a small script to set a default PriceList on the Load of a new Lead form.
Also, we had to write a logic to map that pricelist to the contacts and account while qualifying the price list.
Now, when you try to qualify the lead, you will not get the above error.
Hope this helps!!
