Lead Qualify Business process error

Posted on by 20

Hi Friends,

I am facing this issue while qualifying the Lead on Dynamics 365 v9 online.

it's throwing the below error

"Value cannot be null.
Parameter name: You must select a price list before saving If you contact support, please provide the technical details."

And the screenshot of the error is here.


Any help would be much appreciated.

    Hi Shashikant,

    It might be possible that you have registered plugin on create of contact, account or opportunity create event. While qualifying lead in background, all mentioned entity records created.

    Could you please check any plugin registered on all those entity.  

    Also if possible please share downloaded error log file data here

    Its seems the error coming from plugins , ideally this error is coming when you've not set a price list. I am not sure what exactly you are doing in plugin level , would suggest to write some trace log and see where its failing and set price list before create operation.

    You can take a look few troubleshoot guide.
