Asset posting using BAPI_ACC_DOCUMENT_POST

Hi,

I am trying to post Asset using above BAPI. The error i am getting here is

"Required field GL_ACCOUNT was not transferred in parameter ACCOUNTGL"

How i am passing to G/L Structure is : if G/L Account does not exists then passing only asset number (ANLN1) to BAPI.

So i am getting above error message.

Do i suppose to handle this in different way ? i have seen many posts about asset postings which could not helps me.

we can manually post asset, but could not through BAPI.

can any one suggest on this please.
