Upload BOM with Object dependency history

Hi All,

We have a requriement to upload all BOM history including dependency data.

I tried using BAPI_MATERIAL_BOM_GROUP_CREATE which works perfectly for history data, but doesnt have option to upload dependency.

We want to upload dependency (mainly selection conditions) also in a single upload, including history..

Including history means, if an item is valid between 01.01.2010  till 31.12.2010 , with a selection condition, we want to uplod this item for that period including dependency.,

Regards,

Aby
