Hi,
I have created a custom entity A and created many-to-many relationship from custom entity A to the system user entity. Added a sub-grid on the custom entity A and when we add an existing user, user record will be shown on the sub-grid of the custom entity.
Now, I would like to show the user on the sub-grid automatically when custom entity A record is created. Based on created By field username, I would like to auto populate the same username on the sub grid. Is it possible, could someone suggest how I can achieve this? I have tried by workflow and also using relationship but couldn't achieve. Could someone suggest me how I can achieve this. Thanks
