Master Data enhancement

Hello,

I require to enhance one of the Delivered Master Data extractor. This is coming out of a view.

I went and included in the view the additional field. I am able to see the field in RSA2, but against that field in the Attribute column it has A. This means that field is hidden by SAP.

Hence when I go to RSA6, I am unable to include this field.

Can any one suggest how can I include this field in the extractor.

Appreciate your help.

Regards

Sundar
