large number (strange) in query result

Hi experts,

We have installed BW 3.5 and BW 7.0 (Support Package 5).

I have executed a query with user1 and the result is OK. For example, AMOUNT = 5000 EUR

I execute the same query in the same machine with user2, and the result is very strange. There is a large number:

562.248.000.211.021.235 EUR

The macros are available.

It has the low security.

Has someone any idea?
