Did you check if there are any duplicate entitlements/access items? Sometimes IIQ consolidates duplicates in the provisioning plan, so you may see fewer items there than in the certification.
@tmamouros If I understand correctly, all 16 accesses were removed, but you can still see a provisioning request for 14 of the 16 accesses. Could you please check whether the user has any duplicate access assignments?
For the 2 missing entitlements, verify whether they are marked as Non-Requestable, inherited through a birthright or role-based access, or if they were filtered out by any provisioning policy or customization rule
@tmamouros Please check if those 2 entitlements got filtered out and it should tell you the reason. Is it happening for all users and with all certification or just for a specific ones.
