Fixed Asset data migration using LSMW

Hi,

We are using LSMW for fixed asset data migration using SAP standard program RAALTD01. While executing the LSMW, the asset master data is getting successfully created. However the transaction data throw the following error message

Transaction code not set or invalid

Key of data record which caused termination:

Client = 020 ,

Company Code = ID01 ,

Asset class = Z1300 ,

Old main number = / ,

Old subnumber = / ,

Transaction = / ,

Record type = B .

We tried adding a constant value '0001' to the field BWCNT. But in that case the BDC is failing.

If someone has faced similar issue, please let me know.

Thanks

Mohit
