How to transfer Units Between Distribution In Asset using API -> FA_TRANSFER_PUB.do_transfer

I am trying use FA_TRANSFER_PUB.do_transfer to distribute units in multiple distributions line which we can achieve as below from Application side:

Navigate FA: Assets > Assets Workbench > Assignment

On this screen we can distribute unit to multiple distributions line ( Depreciation expense account, location, employee).

Though the the pl/sql code gets completed normally with success but the distributions which we are trying is not visible.

Below is the code which we used and it completed successfully but with no result as expected:

=============================

declare

   l_trans_rec                fa_api_types.trans_rec_type;

   l_asset_hdr_rec            fa_api_types.asset_hdr_rec_type;
