Task chains = DAG orchestration. Senior pattern: design alongside data layout week 1, failure modes per task (retry/skip/halt), SLA-driven runtime budget per node, telemetry to BTP Audit Log + monitoring. Work backwards from dashboard SLA to ingestion. Tasks exceeding budget = redesign target.

What you will learn

  • Understand the core concepts behind task chains & operations
  • Apply Task Chains in a typical SAP analytics engagement
  • Recognize the 3-5 common mistakes and how to avoid them
  • Position this skill in your personal brand and rate conversation

Module overview

Task chains = the orchestration layer in Datasphere. Without task chains, every Replication Flow + Data Flow runs on its own schedule, dependencies are tribal knowledge, and the 6 AM dashboard refresh fails silently when a source feed is late. Senior consultants design the chain alongside the data layout in week

  1. A task chain = directed acyclic graph (DAG) of:
  2. Replication Flow runs (CDC delta refresh).
  3. Data Flow runs (transformations).
  4. Persisted view refresh.
  5. HTTP callouts (notify Slack, trigger downstream pipeline).
  6. Conditional branches (success / failure).

Senior craft signal — failure handling. A junior writes a chain that stops on first failure. A senior designs failure modes per task: retry with backoff for transient errors, alert + skip for non-critical, alert + halt for critical, conditional notification per severity. The chain is auditable and survives 3 AM ops calls.

SLA-driven design. If the business needs the dashboard at 7 AM, the chain must complete by 6:45 AM with 15 min buffer. Work backwards: synthesis → modeling → ingestion. Each task's runtime budget = SLA / chain depth. Tasks that exceed budget = redesign target.

Prerequisites
