Unable to search item in miscellaneous transaction

Unable to search item in miscellaneous transaction
Content (please ensure you mask any confidential information):

Hi, the user can't search the item while creating miscellaneous transaction (the search doesn't work). The user is able to search item in product information management.

I think maybe he doesn't have "Manage Item Keyword Search Attribute" privilege, but checking on security console, it has the privilege since it has "Product Data Steward" and "Product Manager" role.

Also, i want to point out that, the same user with the same role and data access can search items in TEST Environment. So i think that maybe the problem is not the user but some configuration of the environment. On the other hand, my user (admin) can search item also in production environment.
