SID Error while activation.

Hi All

I am loading the data from DSO A to DSO B. While loading i am getting the error message as

Error when assigning SID: Action VAL_SID_CONVERT, InfoObject ZCUSTOMER

Characteristic value '0000000000' of characteristic ZCUSTOMER is not ALPHA-converted.

I checked the data for field ZCUSTOMER and found there is no data for 000000.

Previously it is loaded with wrong data (00000) for customer. But now, there is no data with 00000 in Active data table of DSO A. Checked the data in DSO A of change log and all the data having 0000 are with the RECORDMODE = N.

I checked in RSRV, but i didnt able to find any error. 

Can you please help on this issue.

Thanks.
