ASKBN - Asset not exist in Company Code

Helo People,

Could you tell us what are the way we can analyse for the situation:

When we execute the transaction: ASKBN, the system shows us that some Assets doens´t exist, but they exist.

We have made some proves and we observed that, for the Company Code A, with the Class 10001, this Asset shows the error.

But in a other Company Code B, with the same class 10001, it runs correctly.

Could you tell us what happend?

Thanks,

Rosana.
