i add it with the Usr prefix (UsrMarge) , but when i save the object, the system return me the following error:
Unable to save structure. Name: OpportunityProductInterest.
Label: Product of the opportunity.
Error: InvalidNameException.
The "Min Quantity" code in the "From" column must start with the prefix "Usr".
Contact the system administrator.
This is because the previous developper created fields without the prefix.
Can i change the system parameters to set the prefix not required ?
