My question is regarding FI object F_BKPF_BLA. I have a requirement to restrict activity for the document types by using authorization groups. From what I know it is possible to restrict the activity on document type based on the authorization group assigned. But for this object to work, each document type needs to be mapped with authorization groups and that authorization group needs to be mapped for F_BKPF_BLA. However, there are T codes like FB01,F-02 so on which doesn't check F_BKPF_BLA while posting document as per Trace data(even though check indicator is maintained as yes for F_BKPF_BLA in su24) . Is there any possibility to restrict posting of document in such cases?
