Symptom
The error message 'Only 170 mapping tasks can be downloaded at a time' appears even when only one mapping task is selected after pressing the 'Download Mapping Templates' button. However, this error doesn't occur consistently but rather randomly.

Environment
- SAP S/4HANA Cloud Public Edition
- "Migrate Your Data – Migration Cockpit" app
- Migrate Data Using Staging Tables
- "Migrate Your Data – Migration Cockpit" app
Reproducing the Issue
- Under Migration Project screen, press 'Download Mapping Templates' button.
- Select one Mapping Task.
- Press 'Download' button.
Cause
Typically, the system does not produce any error when one or multiple Mapping Tasks are selected from among 170 records or fewer. However, occasionally, the system load may increase due to a large number of Migration Objects within a single Migration Project. As a result, errors can occur randomly.
Resolution
- Consider downloading Mapping Task templates for individual migration objects rather than for the entire migration project.
- Consider switching to a different browser or clearing the cache.
- Consider distributing the objects by creating several new projects.
