# Managing DataEngine Functions

## Viewing Functions

1. From the left navigation menu, select Manage Elements (![ManageElementsMenuIcon.png](https://cdn.us.document360.io/89b91113-5dc6-49db-86ec-57b16dc8ce56/Images/Documentation/img-b3d2ad07e044da6d7a37d19d29da0a16(10).png?sv=2026-02-06&spr=https&st=2026-11-08T09%3A05%3A25Z&se=2026-11-08T10%3A05%3A25Z&sr=c&sp=r&sig=UNc52bCu4tR53zXn6Mwfb3e9Yd0UvhUVw55MlEvR%2F%2BE%3D)) and then Functions.

The following properties are displayed for each function:

| Name | The name of the function. If an expansion arrow appears, click the arrow to see multiple revisions of the same function. |
| --- | --- |
| GUID | A globally unique ID for the function. |
| Owner | The owning user of the function |
| Created | The date and time on which the function was created. |
| Modified | The date and time on which the function was last modified. When you modify a function, a new revision is created. |
| Current Version | The latest revision number created for the function. Where there is more than one revision, expand the function in the Name column to list each version. |
| No. Of Revisions | The number of revisions of the function that have been created. |

2. To see more properties of a given function, select the trigger and click Inspect.

## Modifying a Function

Modifying a function creates a new revision with a new revision number. When you want to update your function code, you can build a new image of the function, tag it as you wish, push it to the container registry and then create a new revision of the function pointing to the updated image.

Creating a new revision does not automatically update the revision used in a pipeline. When you create a new revision to use in a pipeline, you also need to update the pipeline to use the new revision.

There is an option to create a local revision of a function. Local revisions cannot be used in a pipeline.

1. From the left navigation menu, select Manage Elements (![ManageElementsMenuIcon.png](https://cdn.us.document360.io/89b91113-5dc6-49db-86ec-57b16dc8ce56/Images/Documentation/img-b3d2ad07e044da6d7a37d19d29da0a16(10).png?sv=2026-02-06&spr=https&st=2026-11-08T09%3A05%3A25Z&se=2026-11-08T10%3A05%3A25Z&sr=c&sp=r&sig=UNc52bCu4tR53zXn6Mwfb3e9Yd0UvhUVw55MlEvR%2F%2BE%3D)) and then Functions.
2. Right-click the function and select Edit.

The revision number is incremented automatically from the previous revision.
3. Make changes as needed:

| Revision Alias | An alias for the revision. |
| --- | --- |
| Make local revision | Check the box to make the revision local. A local revision that cannot be used in a pipeline. |
| Revision Description | A description specifically for the revision. |
| Container Registry | From the dropdown, select the container registry where the image of the function is stored. |
| Artifact Source | Enter the path on the container registry where the image resides. |
| Image Tag | Enter the image tag attached to the relevant version of the container image. |
| Full image path | This is the full path to the image. It is formed automatically from the container registry, artifact source and image tag values that you supply. |
4. Click Update Function.

The new revision is created and listed in the Functions page as a revision of the original function.
