Changed characteristic length is not reflecting in infosource and cube

Hi Everybody,

I have an info object "JOB Number" type "char" of length "15". We have data in respective cubes and ODS's which are having this job number. Now i have changed the length to "20", when i am trying to load data i am getting the error messages as "DDIC_STRUCLENG_INCONSISTENT"..and the detailed error as follows.

The system discovered an inconsistancy trying to access the description. and this situation may arise from changes being made to the structure at program runtime.

waiting for swift response..

Thanks and Regards,

Ramesh.
