C4C Quotation Replication: Print PDF Preview

Dear Experts,

we want to use the C4C - ERP Replication for quotations. If we activate this flag for specific quotation types in fine tuning -> quotation -> document types, the flag for "customer approval" is set automatically to true and no changes can be made.

This means, that "preview" action button in quotation is not available for this quotation type. Why is it like this? And is there any possibility to use Preview and Replication together?

Thanks & Regards.
