Usage of APPLCOMPAT=V12R1M506

SAP has successfully certified the usage of APPLCOMPAT=V12R1M506. For the time being the following SQL features are exploited: LISTAGG built-in function (FL501), explicit casting of numeric values to GRAPHIC or VARGRAPHIC (FL502) & implicit drop of explicitly created database objects (FL506). Raising APPLCOMPAT to V12R1M506 is optional for customers. SAP applications will always check the APPLCOMPAT level before using any new SQL features.
