The following pattern describes how to calculate codes for supplier evaluation.
The KPI auditor (CX_KPI_AUDITOR) defines codes, which are then generated as attributes.
The KPI Auditor is connected to the sales order items (CX_WORK_FLOW) (in this example CX_TRANSACTION instead of CX_LINK_TXN).
This transaction description creates a log cube (CX_LOG_CUBE) between KPI auditor and supplier, when booking the sales order item. Both objects can be accessed by the transaction description via sales order item.
The transaction description writes the codes into the equivalent long cubes (all, year, month) and books the transaction.
