I used the GL Journal Distribution feature to support a german feature for distribution of "food hosting" postings. The created postings are the only in my whole accounting fact table that do notr begin with an documentNo (or a document date in case of Bank Statements). This is very annoying in lists because you can not find out which document created this posting.

In the screenshot you see the acoounting facts detail table of one purchase invoice document. All postings but these two begin with a document number. These two are the reverse postings of the distribution.
