A few days ago PM started asking me once a day when we will have fixed an error he saw at customer site.

I always tell him that it is not a software error, just missing data. I try to explain the issue and that the root cause is the incomplete data given by the customer.

Then he says he will talk with the data import guys if they can fix something and I tell him that from my point of view the data import is fine, but the customer has to provide a full dataset and the "error" will vanish immediately.

He walks to the data import colleague anyway and gets told that everything is ok with the import.

Next day he appears at my desk to tell me that the import seems ok and asks me how we could fix the error and I tell him that it's not a software issue, try to explain it...

I wonder how long he will keep up on it.
