Special Purpose Ledger (FI-SL)
Using ALE you can send the data contents of ledgers from one or more decentral systems to a central system. Data can be transferred either at the same level of detail or in summarized form.
Distribution in the Special Purpose Ledger can also be used if accounting data is required in the central system but is not sent from the local system to the central system in the standard.
In this case you need to define a ledger in the Special Purpose Ledger with the required data fields and then specify that it should be sent to the central system.
The ledger distribution uses the rollup technique in Special Purpose Ledger. You can start a periodic rollup that sends the delta of the ledger data since the last rollup to all interested systems.
