R12.1.3 : WSH_WF_LOAD_TEND is invalid after upgrade from 11.5.10.2 to 12.1.3. Can I drop this object

Hi,

WSH_WF_LOAD_TEND is invalid after upgrade from 11.5.10.2 to 12.1.3.

Can I drop this object? Or this should be validated?

The errors and versions are :

"/* $Header: WSHLTWFS.pls 115.0 1999/11/11 19:45:35 pkm ship        $ */
"
"/* $Header: WSHLTWFB.pls 115.3 1999/11/23 14:10:48 pkm ship        $ */
"
