HANA Spatial function ST_Point() does not work

[sensen_wei2]

Hi Experts,

I am trying to use some spatial functions in my stored procedure, where this problem occured, this statement does not function correctly:

select NEW ST_POINT(lv_pointString,4326) as lv_vehiclePos from dummy;

The Semantic error say: Unresolved function ST_POINT, but in SAP help it clearly stated this cunstructor is supported, what is the matter?

On the other hand, I have another procedure with similar statement which is working correctly:

select NEW ST_POLYGON(lv_polygonString,4326) into lv_polygon from dummy;

Please help
