Contra account in FA

Hi

Please explain about Contra account

In T.code AO90, system explain:

This is the contra account for an asset acquisition posting, provided the posting was not an integrated posting with Financial Accounting.

But when I enter transaction "External Acquisition asset":

Acquisitionasset> Posting> Acquisition> External Acquisition > u2026Acqui. W/automatic offsetting entry

I see contra account still appear on GL? Why is so that?

Please help me. Thanks.
