Beas add many SAP UDF Fields to SAP Tables
But the name of UDF Names different between HANA and MSSQL
This has history reasons.
In general you can use always the HANA Syntax, the internal HANA->MSSQL runtime converter convert this always to correct MSSQL names
But it's better to use single source syntax
Example: Drawing number in Item master data
MSSQL: OITM.U_znr
HANA: OITM.U_beas_znr
use this in follow way
select "<sqlca.udf.beas_znr>" from "OITM"
execute in
MSSQL: select "U_znr" from "OITM"
HANA: select "U_beas_znr" from "OITM"
