restrict attachment from target record

[PrachiI]

We already achieved restriction of attachments when gets attached via compose email for COE's sn_hr_core_case via email Client configuration when user attach an attachment via compose email. We added filter condition as Email.target table is not sn_hr_core_case to the ECC with application Global and default configuration checked.

We need to implement the same for all other COE's. How can we achieve this?

May be you can try changing the filter condition to something like email.target_table.sys_id IS 12345

Accept the solution and mark as helpful if it does, to benefit future readers.

We cannot add/dot walk target table sys_id. Moreover, we tried to add or/or clause/and condition for other COE's which didn't work. Also tried to create multiple ECC for other COE, which didn't help me to achieve for other COE.
