Asset Accounting Error MSG <ZAA>

hey SAP gurus,

I really need your help guys. One of our users is prompted with the following error message in MIGO

S:ZAA:002

Now the above message has no description and hence can not be traced. I remember that this issue was once resolved via a configuration done in the Asset Accounting Section of the Finance Module. The asset class of the asset used in the purchase order was inserted in some list ( in the configuration screen ).

take care ppl
