Delete Master data from SID Table

Dear Guru's,

scenario : I loaded some master data to an existing info object for a new comp code( CC01) . I found the master data is not correct . I want to delete it .

1) I tried to delete using se38 --> RSDMDD_DELETE_BATCH  & also from Maintain masterdata

No Master data deleted

2) I went to SLG1 &  found that log like below ;

Also some SID values found in some cube for CC01

3) I checked in SID Table & found an entry with the Comp Code CC01 & SID.

My Question is :

1) Can i delete the data from SID ,if so how to do selective deletion for only CC01 data , i found in some posts that deleting SID data might give problems when i reload the same master data.

2) How to delete the SID from cube .

Thank you for your time.

Regards,

Sudhir.
