Goal: show how MM teams diagnose Batch Input failures with traceable evidence (messages, fields, and corrective actions).

Deliverable: compact mini case + evidence index (screenshots + notes).

Scope: operational execution and troubleshooting in SM35 (no development).

Context & objective

This mini case documents a real Batch Input execution in SAP that fails during MM01 (Material Creation). The objective is to demonstrate an evidence-first diagnostic approach: identify the exact message, the impacted technical field, and what operational correction would be required before reprocessing.

System & scope

What was observed (evidence-based)

A Batch Input session (MAT_CREATION) was processed and ended in error. The log shows two root error types:

  1. Missing mandatory input: “Descr.” not filled (Message 00278)
  2. Invalid input format for material description field MAKT-MAKTX (Message 00298)
