Recently, while working on qualifying Lead to Opportunity we faced a permission issue.
On Downloading Log file, we found the error message “User with ID 813f0246-55a4-e811-8478-5065f38bf441 does not have Write privilege for the new_bpf_02efda044479424aa7b3c7d8ab4a0a95 entity.”
To fix this issue, we gave Write Permission to the BPF with GUID
02efda044479424aa7b3c7d8ab4a0a95 in a security role under Business Process Flows tab and assigned that security role to the user with GUID
813f0246-55a4-e811-8478-5065f38bf441.
Hope it helps !!
