SAP Error: Max Wait Exceeded

Issue

SAP background jobs are canceled. The following error appears:

Max wait exceeded!

Environment

Connector: SAP ERP on HANA

Resolution

To resolve this issue, increase the max wait time in your SAP environment. You can configure this setting in SAP transaction /n/fivetran/config.

If this error occurs frequently, it may indicate network latency or performance issues between Fivetran and SAP. Contact our support team for further investigation.

Cause

This issue occurs when communication between Fivetran and SAP is delayed during data retrieval. The retrieval process follows three steps:

Fivetran starts an SAP background job using a Remote Function Call (RFC).
The SAP background job extracts a block of data from the database and waits for Fivetran to retrieve it.
Fivetran retrieves data blocks through repeated RFC calls until the full dataset is transferred.

The Max wait exceeded! error occurs during step 2. SAP enforces a maximum wait time to prevent background jobs from running indefinitely if Fivetran loses its connection. If Fivetran doesn't request the next data block before the wait time expires, SAP cancels the background job.

This error doesn't cause data loss. Fivetran tracks replication progress, so the next sync automatically resumes data retrieval from the point where the previous job was canceled.
