CLEARBLOCK Syntax error

Hello Guys,

I am using CLEARBLOCK to clear block and data but I am getting syntax error:

Code:

SET CACHE High;
SET UPDATECALC OFF;
SET CALCPARALLEL 6;
SET LOCKBLOCK HIGH;
SET AGGMISSG OFF;

FIX("FY19")

CLEARBLOCK "CurrentSubmission";

ENDFIX;

Error:

Transaction [ 0xe024c( 0x5d273856.0xe7823 ) ] aborted due to status [1012001].

where "FY19" and "CurrentSubmission" are sparse dimension level 0 members.

It is working fine with CLEARDATA but not for CLEARBLOCK . I tried with all dimension in FIX statement instead of one (FY19) as above.
