Error in updation of location products in Hierarchy

Hi

While generating hierarchy in APO, I have already 3 location products available for a particular hierarchy. I went into change mode, added one more location product and updated the hierarchy. It got saved. I could able to see the new loc product in the screen. But when I come back from the screen and again enter the transaction, the newly added item is missing.

Even I have added the item in the active model also, but still i am facing the same problem.

Could any one throw some light on this.

Thanks in advance.

Regards
