When performing a collective invoice, the system attempts to combine SD documents (deliveries, orders) into one billing document. For various reasons, however, the system may create several billing documents, for example if the SD documents have different terms of payment.
Whether and how SD documents are to be combined or split depends on the billing type and item category. Your system administrator is responsible for these settings.
It is sometimes difficult to understand why the system carries out a billing split. As of Release 3.0, a so-called split analysis is possible in order to make this clearer to you. Split analysis compares two billing documents and lists the fields that have different contents.
You can call up the split analysis function:
In each case, the split analysis can be called up via Environment -> Split analysis.
