Error when assigning SID: Action VAL_SID_CONVERT, InfoObject

Hi Experts,

We are having an error while activating a data inside a DSO DataStore Object. Below is the error.

Error when assigning SID: Action VAL_SID_CONVERT, InfoObject 0SHIP_TO.

I checked in the DTP and the requests are all green. Only the Activation Part Fails.

I found a similar issue here: http://scn.sap.com/thread/1991265

I already reloaded all the Masterdata to BW.

And also checked 0CUSTOMER by running report RSDMD_CHECKPRG_ALL in SE38, but everything is okay.

Do you have any other idea where can I check the cause of the error? Thank you.
