Problem using "BAPI_FIXEDASSET_CREATE1"

Hi,

We are trying to create fixed assets using BAPI "BAPI_FIXEDASSET_CREATE1" and we need to populate some custom-specific fields of BAPI_TE_ANLU structure (ANLU table), but the standard structure BAPIPAREX has a length of 990 positions instead of the 1822 settled in BAPI_TE_ANLU (there are two appends in that structure).

Could anyone, please, help us to find a solution and fill those customer fields? Is there any BAdi or any way to select the values we want to transfer from BAPI_TE_ANLU?

Many thanks in advance.

Best regards,

Miriam.
