If your deduction is listed as "read only" in ADP, it is likely because the deduction is managed by ADP Benefit Enrollment. For deductions to be updated by Payroll Integrations, you will need to ask ADP to turn this setting off.
The setting can be updated at the Plan level by ADP Service Center Representatives for all employees under the Universal Access mode. Select Setup > Benefits > Plan Setup. Find the plan to be released, select Actions, and click on Suspend Payroll Deductions.
After this is done, the deduction can then be edited through the Payroll Integrations application.
