Unable to add the attribute in Data Warehouse (DWH), when we create a new attribute with same values, we are able to add in DWH.
The Attribute belongs to an object of type “Subobject” and the attribute is “inherited” from the Master. The Attribute needs to be configured on at the Master object level.
Example: The Attribute belongs to an out of the box object, like the Project object, but it is inherited from the Investment object.
You can identify those attributes that fall under this scenario if they appear under a different Database Table IE INV_INVESTMENTS, instead of odf_ca_project.
Release: All Supported Release
