transfer negative stock of one material to another

Hi,

I have a stock count of -35 on material number 5254520 and 34 in material number on 100315911.

I need to move the -35 from 5254520 and put it against 100315911.

The reason being there is "Blocked for procurement" indicator set on material

5254520. For some reason, 100315911 is the new material number replacing the other.

Regards,

SS
