Error: When change the status value of lead

Hi,

I am getting this warning "Conversation actions unavailable as you are unauthorized to create an account", when I edit the lead status value and hit on save.

Individual customer > Select any customer> select lead in its lead tab> edit

I have setup org structure and restrictions on customer and lead. as per this https://scn.sap.com/thread/3835800

So X org unit can not see the customer and leads of Y org unit.

So, X org unit can view and edit its customer and leads only.

I tried to with unrestricted the customer from access restriction but does not workout.

Just for the information: I have added 2 addition additional vales in status fields through fine tuning.

Thanks
