13 Building the Application Data storage layer & Using calculation views for complex application logic

14 Building the Application Data storage layer Created a Custom Schema with 60 Custom Tables - Master Data (sourced from Non-SAP systems) - Master Data unique to Application - Mapping Tables - Data Staging tables (for longer running views) - Transaction tables Tips: Minimize Data Staging Don t be afraid to have complex business logic determined on the fly in Calculation views - Event/Action Log Tables Used.hdbtable artifact to create [in future projects will move to CDS] No major issues - though Primary Key & Column Sequence changes need careful attention 2013 SAP AG or an SAP affiliate company.

A monthly value of 300, might be split into 30 days of value 10 Date level distributions P Tip: External Sources U ECC Tables Using Calculation Views for Allocations makes unit testing much easier than SQL embedded within a procedure 2013 SAP AG or an SAP affiliate company.

17 Virtual UoM Conversion, Complex Calculated Measures & Delta Processing P xsjs Delta Difference Calculated U Column Format (Target UOM) UoM Calc Conv BAV Sent Data Tip: Use the power of Hana to virtualise complex logic in Calculation Views Transaction Table Row format with a base UoM (Weight and Volume) Keep Procedure logic as small as possible 2013 SAP AG or an SAP affiliate company.
