Detailed reports include, in short, your entitlements which are projected for a specific usage year. Said projected total amount shows how much remuneration you are expected to receive at the end of the notification period.  (The total amount is constantly updated. Usually it is adjusted upwards because successive reserves are dissolved, but sometimes downwards if, e.g. we unexpectedly receive more contribution notifications than anticipated.)

The distribution takes place in several stages due to the long statutory notification periods. There is an initial distribution with an initial amount, several subsequent distributions with further partial payments and eventually a final distribution when the notification deadlines expired and the distribution budget can be completely dissolved. You receive your overall entitlement at the end of the distribution cycle. The distributed amounts should, when added up, correspond to the amount shown in the last detailed statement.

The payout notifications you  usually receive with a settlement always state the current remuneration entitlement and the amounts already paid out in the meantime (indicating the date of any related older payout notifications). The statements therefore document the progress of the “partial payments” of the advised total amount.
