Adding Metadata field for Maps in SDL Tridion Docs

Hi All,

I am trying to add a new custom Metadata List field for Maps in SDL Tridion Docs.

In order to achieve this I have updated FieldSetup.xml  in (E:\InfoShare\App\Database\Migration\DatabaseIndependent\Custom.Setup) location and also MetadataConfig.xml file in clientConfig directory.

But, when we try to update the properties I get ( The FieldValue "FCUSTOMMETADATA" cannot be returned, because it is not initialized.)

Thanks & Regards,
