Supplier ID in Pam field

Is their a way to make supplierID show up in PAM

The following steps will make the field visible but not editable.

To do so open up the PAM folder - typically “C:\Program Files\NitroSell\NSc PAM - RMSSO” and edit the file Fields.ini.

In the [Enabled] Section

Add a new line SupplierID=1

Scroll to the bottom and you will find the [ReadOnly] section.

Add a new line SupplierID=1

The button to remove Attribute in Attribute list is grey out which I am not able to remove any Attribute.
How can i fix that.
Thank you
