Invoice Release and MRBR

Hello,

My client puts a manual block on the invoice before saving the invoice. The FI docs have been released but when they run the MRBR report these invoice documents are still showing up as manually blocked invoices. When they try to release them from MRBR, they receive an error that says "No clear document possible for changing" (RW019).

I am not sure if this is due to the fact that the ZP document related to the invoice is archived.

Is there any OSS Note relevant to this situation or any solution possible?

Any help is appreciated.
