Hi partner,
We need to check the security role of the user.
In the security role, each BPF has its own set of privileges. If the user does not have the Write privilege of a BPF, then the user cannot move to next stage.
So we need to ensure the user has the Write privilege of the BPF in his security role.
Demo:
The user does not have the Write privilege of the Oppotunity Sales Process.

Then when he goes to the Opportunity and click Next Stage, he will see an error.


If he has the Write privilege of the Oppotunity Sales Process, he can go to next stage successfully.
