Attachments Not in Invoice Inquiry

Hi,

I can see attachments on invoice entry screen, but not on invoice inquiry screen. I get an error uploaded in the attachment.

Can anyone please let me know what setup needs to be verified for this or what function or menu needs to be adjusted to make attachments visible on invoice inquiry screen.

This is happening for a responsibility. I can see the attachments through another responsibility on invoice inquiry screen.

Can anyone suggest which function is to be used to display the attachments on invoice inquiry screen.

We are using r11 version.
