# About the eCOA-Clinical Operations Connection

With the eCOA-Clinical Operations Connection, organizations with both an eCOA Vault and Clinical Operations Vault can exchange data and documents in near-real time. The eCOA-Clinical Operations Connection exchanges the following data.

Data created and updated in the Clinical Operations Vault and sent to the eCOA Vault:
* _Studies_
* _Study Countries_
* _Study Sites_

Documents created and updated as CrossLinks from the eCOA source Vault to Clinical Operations target Vault:
* Study Design Specification
* _End-of-Study Participant_ Reports (_Final Subject Data_ in Clinical Operations)

To use the eCOA-Clinical Operations Connection, an Admin must complete <a href="/en/gr/60667/">configuration steps and activate the connection</a>.

## How the eCOA-Clinical Operations Connection Works

For Studies in Clinical Operations with the _Connect to Vault eCOA_ field set to **Yes**, Vault creates new records or updates existing records in the following scenarios: 

* When a user creates or edits a _Study_ record, Vault creates or updates the _Study_ record in the eCOA Vault.
* When a user creates or edits a _Study Country_ record in the Clinical Operations Vault, Vault creates or updates the _Study Country_ record in the eCOA Vault.
* When a user creates or edits a _Study Site_ record in the Clinical Operations Vault, Vault creates or updates the _Study Site_ record in the eCOA Vault.
* When the system generates a _Study Design Specification_ in the eCOA Vault, Vault creates or updates a CrossLink in the Clinical Operations Vault.
* When the system generates an _End-of-Study Participant Report_ in the eCOA Vault, Vault creates or updates a CrossLink in the Clinical Operations Vault.

### About Record Creation & Update

When creating a record through the connection, Vault also populates the _Link_ (`link__sys`) field on the target record with the source record's _Global ID_ (`global_id__sys`). These fields let Vault know which records to update in the target Vault when you update data in the source Vault.
