Answer
Assuming the IAL's permissions are otherwise fine, query the view directly under the IFSINFO schema instead of using the &IAL. substitution prefix — for example, IFSINFO.<view_name> rather than &IAL.<view_name>. The &IAL. prefix is meant for use inside the IAL-substitution context itself (like within another IAL or report definition), not as a general-purpose schema prefix to type directly into an arbitrary SQL client tool.
