Loading error "Master data/Text of Characteristic ZMAT already deleted"

Hi,

I have some problem about SAP BW loading.

while loading I'm getting this error "Master data/Text of Characteristic ZMAT already deleted"

and loading is failing.

So when I try to loading again sometime loading is completed but sometime is failed with this error.

I try to find out root cause and I check table RSMASD there is ZMAT entry this table.

How do I remove the entry?

How can I fixed this problem ??

Now my SAP BW is 3.0 B and support package 26

Hope this helps...
