fn_LShortNameToLCID in SQL Database

My question sound stupid but i didn't understand and searching on google didn't helped either. I have a SQL query which i use in SCCM Reporting. I just want to say that my hands are bit tight in SQL and database related stuffs. Below is the SQL query. SELECT top 3 * FROM fn_appdtclientsummarizedstate(dbo.fn_LShortNameToLCID(1033)) acs This is, i get from existing report (SSRS). I checked the SCCM database but this table, views is not there. Hence i can't make the modifications as needed. If you can help me then i would be very grateful. I spent almost 2 days but no luck finding/understanding this query.
