HANA Modeling: Table function in Join node is not fetching data

[darshansomaiah1]

Dear SCN Members, lars.breddemann,

I have created a table function which fetches the data from 0 to 23 as Hours i.e., using a Time series in sqlscript as follows:

FUNCTION "SCHEMA_A"."TF_TRIP_HOURS"()
RETURNS TABLE("TRIP_HOURS" Integer,"DUMMY_MEASURE" Integer)
AS
BEGIN
/* Gives the Hours in a day (0 to 23) */
RETURN SELECT "GENERATED_PERIOD_START" "TRIP_HOURS",1 AS "DUMMY_MEASURE" 
FROM SERIES_GENERATE_INTEGER(1, 0, 24);                      
END

I have used as a Cross Joined with the other projection where I have used other view, but the data fails at Join node. The environment of HANA is SPS 10 (v 1.00.36)

Cross Join in Join_1 node as follows:

If I execute a SELECT COUNT(*) FROM VIEW which has TF gets zero count.

And the interesting part is it is working fine in the environment which is SPS 12 (v 1.120.16)

If I execute a SELECT COUNT(*) FROM VIEW which has TF gets non-zero count.

Please suggest if the above operation is because of version or SP issue or it is due to modelling issue on TF design since I could not find the valid SAP Note on the above case.

I did a refer on the following threads though:

Dear SCN Members,

Please suggest if anybody encountered similar issues with respect to User defined Table function in HANA.

Thanks in advance.

It was an service pack issue. Issue resolved after the upgrade to SPS12.

Thanks,
