The ASUG Perspective – Innovate Vs Execute

“It’s not just about acquiring the SAP S/4HANA licenses—it’s about what you’re going to do with those licenses, the move should be about eliminating technical roadblocks and barriers of the past, and then fostering a climate where companies can take advantage of new business opportunities as a result of a nimbler technology backbone.”— Geoff Scott, CEO, ASUG

“When asked which of the following are key barriers or challenges to your organizations innovation – 68% of ASUG members responded that it was…

“Lack of Resources (Budget, Time, and Staff)”.

60 Years of ABAP

• SAP R/2 release in early 1980’s• All customizations done in ABAP, a 4GL developed in 1980’s• ABAP was modeled after COBOL, a popular programming language for mainframes

• SAP R/3 released in early 1990’s• All customizations was done in ABAP

• SAP ECC was released in mid 2000’s• All customizations was still done in ABAP

• SAP will support S/4HANA until 2040• Is ABAP still the right choice for

Customizations?

• SAP S/4HANA was released in 2015 (approx.)• All customizations are still done in ABAP

SAP’s view of ABAP Customization

”The more you can rely on standard business processes, the lower your implementation costs and quicker the time-to-value”…. SAP Value Assurance for S4H

Customers purchase SAP for their integrated business processes and packaged software…..

Not for programming in ABAP

Z-Programs written 10/20 years ago to be remediated & moved to S4H = TECHNICAL DEBT

Long and expensive ABAP development efforts

Extensive and laborious system maintenance efforts (Patch / EHP upgrades)

Expensive and lengthy code maintenance and enhancements

Lack of new ABAP talent

Why migrate when you can eliminate?

Approaches to Integration

ETLExtract, Transform & Load

• Geared towards huge volume, highly parallel, repetitive and scheduled data movements

• Useful for feeding massive amounts of data from one system to another in a timely fashion

• Consistent and repeatable basis

• E.g: Integrate all customer data from SAP, SalesForce, Oracle and 2 other legacy applications overnight and load into a MDM (Master Data Management) Solution

EAIEnterprise Application Integration

• Geared towards transactional data integration, primarily PUSH driven

• Useful for keeping transactional systems in sync by replicating data in the right format for the target system

• Generally workflow and process-flow driven

• E.g: Salesperson enters customer order in SalesForce. EAI picks the order, transforms it from SalesForce format to SAP format and creates a sales order in SAP

EIIEnterprise Information Integration

• Geared towards reading and posting quick snapshots of data, at a high frequency

• Primarily a PULL engine that waits for a request, splits across multiple sources, gathers data, merges them together & displays

• Generally user-interaction driven

• E.g: Salesperson picks up delivery status and it pulls Account data from Salesforce, Order and Delivery information from SAP and mashes it up and shows in a single page

• Discover all ABAP customizations• Visualize it for Business Stakeholders to comprehend• Find the total cost of ownership for each ABAP customization

• Time, effort and cost to migrate to S/4HANA• Time, effort and cost to maintain the customizations in S/4HANA

• Hint: How many patches / EHP upgrades per year

• Categorize the ABAP Customizations

• Reports (Z-Reports)• Self-Contained Applications (Z-Tcodes)• Applications embedded as part of the SAP process

• Modernize and move your ABAP Customizations to Digital Edge


Introducing NANCI – SAP ABAP Discovery and TCO Analysis

• Quickly Discover all ABAP customizations

• Visualize it for Business Stakeholders to comprehend

• Find the total cost of ownership for each ABAP customization

• Time, effort and cost to migrate to S/4HANA

Summary of Remediation & Maintenance cost

Details of remediation cost by ABAP Object

Details of maintenance cost & TCO by ABAP object in S4H


Categorize your ABAP Customizations

• What are your stand-alone self-contained customizations?• How many of your customizations are embedded into SAP processes?• Are they really part of core process? Can you de-couple them from core?• How old are these programs?• Do you have the internal knowledge on the original requirements & design?• Have the requirements & usage changed over time?• How much is the usage? Do you still need this program?• Business impact of deprecating this Z-application• What business enhancements are needed? What is the technical impact?• Is it time to modernize these applications? How would it look?• What is the total cost of remediation to S/4HANA (resource availability, efforts)• What is your total cost in maintaining them in S/4HANA

• Upgrades, Enhancement request, Dev & testing support, Future-proofing, etc.• Opportunity cost of spending your time in maintenance vs innovations
