How to perform second step of loading in the Account alias issue through FBDI for multiple rows?

Hi I am trying to perform Account Alias Issue transaction through Inventory Transaction FBDI. This is successful for one row. But when we keep multiple rows, and in the first step when we do Load Interface file for Import- it was successful, but in the second step, in Create Inventory Transactions, when we try to submit, it asks for Transaction Header id which is compulsory. Before this step, when verified from backend, the transaction header id is different for different rows. How can we do in this case for multiple rows??

Can anyone guide me how to do this?

Thanks,
