I need to add a new custom column in services for object (GOS) in attachments tab in GMGRANT T-code.

[Shalini_1730]

I have a client requirement where we need to add a new custom column DOCUMENT TYPE with F4 help to select the document type in Services for Object in attachments tab in GMGRANT T-code. 

Changes should be applied in the Grant Master data module under the GMGRANT T-code.

Please find the attachments for your reference.

Can anyone help me out if it possible to implement this or not?

Thanks in advance.
