INT210: Does and Don’ts from BPMN Development

SAP Teched Las Vegas © Figaf 2016

• SAP PRO expert• Worked on two BPM projects• Product developer of Figaf Tools to

improve PI/PRO for customers• SAP PRO Instructor

Daniel Graversen



• Based on my conversation with other developers and experts• Gives you lessons on what you need to avoid in order to complete a

successful project


• Technical BPM• Process Development• Process information

Agenda

Technical BPM



• Can be avoided on many occasions because of new design patterns• Data types• BPMN does not support full XSD formats like IDOC, RFC and some external

definitions need to be changed• Create own internal data types in ESR to simulate data

• Use the claim check pattern to save messages if you need more data after

When used with ”PI”


• Performance of the BPM engine is much better ccBPM• Not a valid reason for avoiding processes• Can use it in more instances• Avoid Big Data structures/contexts that are updated many times

Performance


• No tool auto process• Do a redesign if a BPMN should be used• Sync/async patterns supported• For a lookup, forward the message into PI on the new interface• Bundling

• Simplify the process• Testing will be required

ccBPM to BPMN


• If you seriously want to use BPM, you will need to use NWDI• Multiple developers to support and develop on the process• One track for the BPM development• CM Services work well with CTS+

• One track for supporting processes if you are doing long term releases and bug fixing. • CMS seems better for this

• One software component for each process• It will also require EAR, EJB, and Web for J2ee and UI components• May also have BRM for rules, DB for tables

NWDI

Process Development



• A flexible platform where it is possible to model the process• Integration to different systems• Easy to create first model and show who it can handle the process

Why make process in NW BPM


• The business know how the first process should work• Have a change log of what is going on; otherwise, nobody will know

what is going on when making changes• Be as precise as possible:• Process diagram of what should happen• Field level information

Business Modeling


• Business model• Where the business can make their design• May have multiply steps that will be executed within one task• Can use NWDS as a modeling tool and NWDI as a repository, although it is a

little too complex to be used as such otherwise SAP PowerDesigner may be useful.

• Technical model• The one that will run. • May have technical details not required on main process

• PI interfaces• Reporting to data sources for OPI

Models


• Now only develop in SAPUI5--other methods are not relevant• Generator for Start and Tasks• Easy to use• Now it supports the use of tables and substructures• Ordering of the message follows the XSD

• Easy for creating simple tasks• If you want an abundance of logic, you will need to code it yourself• Gives good flexibility to monitor what is going on

SAP UI5


• Introducing fields into already generated screens• Logic based on the field and the information• Hidden fields need to be deleted in UI• Value help and help values are supported in OData, but need to be

implemented

SAP UI5 Challenges


• Be able to see what was done earlier• In comment setting a comment about how to see completed form• Make few changes in document to be able to read the submitted form

Look into history


• If you want bigger projects, the abilities of the BPM may be limited• Only persist data at end of process step or save button.• You may not be able to complete a lookup with backend data • Limit data in the BPM context• Persist data in JPA, and make extra calls to it in UI

Larger Processes


• Framework that builds on top on the BPMN solution• Screen generation based on Excel with fields/variables for process• Handles UI operations using UI5• Gives you the ability to persist the UI between tasks• Callbacks made in Java to give an easy way of interacting with the

user• Services like lookup, help values, and overview screens

ABPM from SAP Consulting


• Minimal data in the process context; the rest should be in Gateway services• Use Gateway services to call the backend service to execute data in

the backend• UI5 frontend• SAP Mentor Abdulbasıt Gülşen has tried this approach

Make Your Own Framework

Process Information



• Process documentation can become too much• Need governance in progress, otherwise the documentation is outdated =

worthless• If it becomes to difficult to update, it will not be updated

• Consider:• Legal requirements• Support cases--what can go wrong and how to solve the cases• Future development with the new development team; the team’s needs

Documentation


• BPM information can be shown in the inbox to give the user more information on what is happening• Inbox is Fiori-style, so it has extension points• Customize the inbox to give more information regarding the task, so

the user doesn’t need to open more of the task

Fiori Inbox


• Process can stop working if an illegal operation happens• Use a monitoring tool to figure out what is happening• JMS events has been added• Listen to the JMS queue of the BPM events• Either an application or setup at JMS communication channel on it

• SOLMAN has a monitor for failed BPM• Must have the organization to support the processes that will fail

Monitoring


/bpmanalytics


• Gives much better opportunity to monitor what is going on• Must be the business that requests it, it is not an IT decision• BPM must have reporting data source to get data to process• The auto generated data must be extended with data from the view

to select even more from the process• Basic work can be done some what easy• More advance development require HANA experience

OPI


Considerations


• Processes is complicated.• The first attempt will not be correct so be flexible • Expect that it will take longer time to get it done• Support organization new tools can require a different set of skills to

monitor• Short running process is best otherwise versioning should be used on

UI code

Considerations
