# Administrating new projections

## After adding new projections

The OData Connector caches all available projections. Right after you publish new Custom Projection, it is not visible in configuration and cannot be registered. The projection cache will refresh every hour (or something like that).

You can manually refresh the projection cache via the **Configuration** page in **Miscellaneous** tab via the **Synchronize now** -button.

In order for the new projection to appear in Flow studio, refresh the projection list cache in the machine step.  &#x20;

1. Open the step, click ***Refresh***&#x20;
2. The new projection appears in the projection list
