Non-admin users are unable to link RITM to Incident on Related ListIssue Non-admin users are unable to link RITM to Incident records in the Requested Items tab. After clicking the Edit button and attempting to add an RITM, the RITM does not reflect after clicking the save button. Key error messages include 'User is not authorized to update 12M entries for table sc_req_item' during the /slushbucket.do transaction.ReleaseAllCause1. A security fix (PRB1834114) introduced in Xanadu Patch 8 and Yokohama releases enforces field-level ACLs, preventing users from modifying related list entries if a field is marked read-only at the dictionary level. 2. Specific ACLs on the sc_req_item table, such as the one requiring the 'admin' role, block non-admin users from updating records.

Identify the ACL restricting write access to sc_req_item records, for example if there is one requiring the 'admin' role for sc_req_item.*/write access. 2. Review and De-activate the ACL to resolve the issue temporarily. 3. Decide whether to remove the 'admin' role requirement and replace it with a role like 'itil' to allow non-admin users to link RITMs permanently.
