Hi Team,
I have a main form, and when I click the plus icon for inserting line items, I use a drawer page form for DML operations. When I try to insert a new record using the drawer button, the system throws the following error:
“No checksum found for lost update detection. Can only perform UPDATE or DELETE for existing rows.”

Could you please help me resolve this issue?
Thanks in advance.
Regards,
Rohith
