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

© 2013 SAP AG or an SAP affiliate company. All rights reserved. 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

- 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

Tips:

Minimize Data

Don’t be afraid to

have complex

business logic

Virtual Allocations

Duration (Start / End Date), Year and Monthly Values (from Sources without Dates) needed to be Allocated to Valid Dates within a Validity period by business rules, such as Daily, Weekly, Monthly or other custom logic

E.g. A monthly value of 300, might be split into 30 days of value 10

Tip:

Using Calculation

Views for

Allocations makes

unit testing much

easier than SQL

procedure

Virtual UoM Conversion, Complex Calculated Measures & Delta Processing

Tip:

Use the power of

Hana to virtualise

complex logic in

Calculation Views

Keep Procedure

logic as small as

possible

High level UX

• Utilised SAP UX Team

• Used whiteboard / post-it notes & interactivity PPT

• Next project may use SAP Splash

Main SAPUI5 Issue

• On Premise Native Hana SPS10 SAPUI5 Library Version 1.28

• Smart Filter & Smart Table has some bugs resolved >= 1.36.10

Solution: FLP uses On Prem SAPUI5 ‘Smart’ Apps use Public HCP SAPUI5

1.28 1.36.10

Next Steps:

• PoC of HCP for Front End build (should unify SAPUI5 versions, improving experience)

Tip:

Create your own

template(s) and

use as basis for

building Apps
