Need to Close work object in Work list table

Hi All,

we have a requirement as below.

once user submit the request we are creating work object and routing to 3 users using split for each. if none of the user takes any action, we need to auto reject the work object after 10 days. for this we Using SLA on assignment. in SLA we are calling activity and sending mail. this is working fine and we are using OOTB activity Updatestatus for changing the status in work- Class table.

but in Assign- worklist table, status is remaining the same, even though SLA is completed successfully.

we tried with ResumeFlow in SLA and Forcecaseclose activity also. but it is not removing the cases from Assign workList table.

please suggest any solutions.

Thanks in Advance.
