Using CDS table function in Open ODS View: Error aggregate

Hello,

I have created a CDS table function and am using an Open ODS View on top of it.

When I want to see the data of the Open ODS View (right click 'Display Data' in RSA1) it works but when I check the option 'Use DB aggregation' the system gives me following error:

column store error: search table error: [2991] table config for index TCW::SAPDAT:_SYS_SS_CE_2156388_140338331242496:4_R ...

is not valid;QueryId: C7BGEF9TFF37CJ7Q34EVOXRNH:N_OV/[Request Info: Object Name = "SAPDAT"."0BW:BIA:D0TESTJAN_OV", FM ...

[Name = TREX_DBS_AGGREGATE]

Error 2.048 has occurred in the BWA/SAP HANA server

Error reading the data of InfoProvider D0TESTJAN_OV$X

Any ideas?

Thanx in advance,

Regards,

Jan
