Aftter posting the movement type 952, which is a stock write on.. the moving average price shoots upto a very high junk value. I am not able to understand the reason for this.

We then manually chage it using MR21. The problem is that we have to keep a track that this does not happen as it leaded to very high inventory value and figures become mind bogling at times.

Incase any one of you has faced a problem with moving avg price giving absurd values plz let me knw.

thanks
