The goal of this project is to align data from version, item and account assignment of purchase orders. Via the bubblemodel you are capable of structuring your datamodel in a transparent way. It is a handy method to give insight in the BW datamodel. It helps you to explain the black box, what BW often is to your business. Quite simple!! You centralize the key figures, measures, like it is in a BW – cube. Around you can organize the key fields of each appropriate table. In addition you can assign the according extra fields, needed for reporting. Adding the fields and tables will obtain a transparent view for your business. This handy way of projection of your ECC – tables, will be a great advantage as well, when designing Hana Models.
