where does R17024 retrieves Major Accounting Class from?

I am setting up R17024 to work with non-serialized Item numbers and so create Assets.

I still receive one error preventing asset creation:

CAUSE . . . . Major Accounting Class was not

found in User Defined Code

for system 12 , type C1 .

RESOLUTION. . Enter

a valid Major Accounting Class or use Visual Assist to search

for a valid

value.

Where can this be missing?

Depreciation Defaults have been set up in P12002 for the cost object.

Thank you very much!
