When migrating an SAP S/4HANA system and changing the System ID (SID), you might encounter issues with graphical charts in certain transactions. A common example is Transaction DB02, which shows database performance and space statistics.

After migration, executing DB02 may result in : IGS not available (RC=1), Charts not available

Root Cause
The Internet Graphics Service (IGS) is responsible for rendering charts in SAP GUI. It communicates via an RFC destination named IGS_RFC_DEST. When the SID changes during migration, this RFC destination still points to the old SID, causing the connection to fail.

Symptoms

• Charts in DB02 are missing.
• RFC destination IGS_RFC_DEST fails the connection test.
• Error message: IGS not available (RC=1).

Solution: Update RFC Destination
Step 1: Go to Transaction SM59

Navigate to RFC Destinations.
Search for IGS_RFC_DEST (Type: TCP/IP Connection).

Step 2: Test the Connection

Perform a Connection Test.
It will fail because the program name and gateway details are incorrect.

Step 3: Update the RFC Parameters
Modify the following fields:

• Program Name: IGS.<SID> (Replace <SID> with your new system ID.)
• Gateway Host: Set this to the CI (Central Instance) server host of the new SID.
• Gateway Service: sapgw<nn> (Replace <nn> with the instance number of the CI.)

Step 4: Save and Test Again

Run the Connection Test. It should now succeed.

Step 5: Verify in DB02

Execute DB02 again. Charts should now be visible.

Additional Tips

• After any SID change, review all RFC destinations in SM59.
• Check other services like SAP Gateway and IGS to ensure they are running.
• If you use load-balanced systems, verify the gateway host points to the correct application server.
