BAPI_PBSRVAPS_CHANGEKEYFIGVAL2 Not Working

Hi

I am facing problem using BAPI_PBSRVAPS_CHANGEKEYFIGVAL2. I am getting the error message as below

Time period 20120701000000 to 20120728235959 does not exist or cannot be changed

However I checked the SBP and timebucket profile, this date falls in the horizon range.

On detailed debugging, we noticed that standard BAPI is referring to table RSDIOBJCMP.

For the infoobjects that we are using there is no entry maintained in the table RSDIOBJCMP ( IOBJNM  - Infoobject Name and OBJVERS as "A")

Can this be the reason for the error message that we are getting

Any help is highly appreciated.
