MRBR- Blocking reason: quantity

Hi ,

I have an issue with MRBR - Release Block for invoice.

We have a set up that if we have any quantity variance in during the posting of MIRO, then the invoice doc will block.

user will user the MRBR transction to release the block.

Now user dont what this option. how to relase this.

We have other options too i.e Blocking reason: item amount, Blocking reason: price etc., we want to remove the quantity variance option only.
