SCMON Setup and Execution Guide

Purpose: The ABAP Call Monitor (SCMON) is a tool designed to monitor the execution and usage of ABAP code (function modules, method calls, etc.) in your productive SAP system. It helps identify which custom code is actively used and which business processes call specific ABAP objects. On average, 40-60% of custom code remains unused in productive landscapes, making SCMON essential for cleanup activities before migration projects like SAP S/4HANA transformations.

Key Capabilities

• Tracks usage frequency of ABAP objects
• Identifies calling business transactions and processes
• Provides data for custom code decommissioning decisions
• Supports long-term usage analysis when combined with transaction SUSG

 Configuration Steps (Local Activation (Direct in ABAP System)

• Execute transaction SCMON or /SDF/SCMON (for NW < 7.4 SP13)
• Click the Activate button

• Configure activation settings:
• Scheduled Deactivation: Specify when monitoring will automatically stop
• Record Limit: Set maximum number of records (default: 200 million)

• Save the configuration

Configure Time Slices

• In transaction SCMON, navigate to ABAP Call Monitor > Configure Time Slices

• Set Maximum Number of days for data retention (default: 7 days, recommended: up to 365 for detailed analysis)

• Time slices enable analysis of monitoring progress over specific intervals
• SCMON automatically deletes data older than the configured retention period

Note - Please complete the required configuration steps in both corresponding systems so that the comparison for the usual analysis can be performed.
