TADM12 – Technical Implementation and Operation II of SAP S/4HANA and SAP Business Suite — Lesson 1: Advanced SAP Architecture, Connectivity, Web Services, ICM, SAProuter, and Secure Communication

Learning Objectives

• Interpret the SAP structures, data, settings, roles, and dependencies shaping this lesson.
• Perform the workflow and create a reviewable advanced SAP connectivity and security map.
• Evaluate the condition where an ICM service exposes an unintended communication endpoint and choose proportionate follow-up.

Detailed Topics

• Advanced SAP Architecture applied to the course scenario, SAP behavior, and expected evidence.
• Connectivity applied to the course scenario, SAP behavior, and expected evidence.
• Web Services applied to the course scenario, SAP behavior, and expected evidence.
• ICM applied to the course scenario, SAP behavior, and expected evidence.
• SAProuter applied to the course scenario, SAP behavior, and expected evidence.
• and Secure Communication applied to the course scenario, SAP behavior, and expected evidence.

Instructor Demonstration

The instructor traces a scenario involving an experienced Basis team strengthening production operations across ABAP, Java, HANA, interfaces, and high-availability dependencies. The walkthrough connects SAP navigation, process logic, settings, system messages, and the evidence captured in advanced SAP connectivity and security map. It also tests the condition where an ICM service exposes an unintended communication endpoint.

Hands-On Exercise

Complete a controlled activity covering Advanced SAP Architecture, Connectivity, Web Services, ICM, SAProuter, and Secure Communication. Preserve the final result in advanced SAP connectivity and security map.

1. Confirm the process objective, required roles, source data, and expected system outcome.
2. Perform the SAP workflow while recording documents, settings, messages, and observations.
3. Introduce the stated exception and isolate the first point where expected behavior changes.
4. Document corrective action, ownership, retest evidence, and operational handover.

Scenario Analysis

• Identify the SAP object, rule, setting, or process step with the strongest influence on the outcome.
• Compare two defensible responses and explain their business, technical, control, and evidence trade-offs.
• Decide how the advanced SAP connectivity and security map should be approved, retained, retested, and updated.

Troubleshooting Guidance

Begin where expected SAP behavior first differs from the observed result. Check organizational assignments, master data, configuration sequence, authorization, integration, and transaction evidence separately. Treat “an ICM service exposes an unintended communication endpoint” as a testable hypothesis until relevant settings, logs, documents, and outcomes confirm the cause.

Validation Checklist

• Required SAP structures, master data, roles, settings, and dependencies are present.
• The advanced SAP connectivity and security map connects the conclusion to objective, reviewable system evidence.
• Normal processing, the stated exception, integration behavior, and follow-up were tested.
• Corrections, ownership, retest criteria, documentation, and operational handover are complete.

Lesson Outcome

Learners can perform Advanced SAP Architecture, Connectivity, Web Services, ICM, SAProuter, and Secure Communication, explain the SAP behavior, and defend the result through advanced SAP connectivity and security map.
