The number on the overview screen corresponds to the total number of LUWs (see also question 1) that were written to the qRFC queue and that have not yet been confirmed. The detail screen displays the records contained in the LUWs. Both the records belonging to the previous delta request and the records that do not meet the selection conditions of the preceding delta init requests are filtered out. This means that only the records that are ready for the next delta request are displayed on the detail screen. The detail screen of Transaction RSA7 does not take into account a possibly existing customer exit.
