 Data lineage in Microsoft Purview is [automated](#lineage-collection) for many assets in on-premises, multicloud, and SaaS environments. While we continue to add more automated sources, manual lineage allows you to document lineage metadata for sources where automation isn't yet supported, without using any code.
 
 To add manual lineage for any of your assets, follow these steps:
 
 1. [Search for your asset in the data catalog](how-to-search-catalog.md) and select it to view details.
-1. Select **Edit** and navigate to the **Lineage** tab.

-1. Select the relationship type:
-    1. For upstream lineage - select the relationship as **Consumes**
-    1. For downstream lineage - select the relationship as **Produces**

 ### Known limitations of manual lineage
 
 * Current asset picker experience allows selecting only one asset at a time.
-* Column level manual lineage is currently not supported.
+* Column level manual lineage is currently supported for lineage between two data assets, while not supported when process asset is involved in-between.
 * Data curation access required for both source and target assets.
 * These asset types don't currently allow manual lineage because they support automated lineage:
     * Azure Data Factory
