Good to hear you are making progress.
There are explicit warnings in the documentation that values for SCHEMA etc can be case sensitive. For example:
http://support.sas.com/documentation/cdl/en/acreldb/68028/HTML/default/viewer.htm#n1h1m1ethqxwryn1wu...
So unless the case matches, for you upper-case PH, you don't get any tables.
