Accessing a variant configurated transaction thro BAPI?

Hi,

The transaction Create Quotation (VA21)has been subjected to variant configuration.

In case i try to execute the same process with the help of BAPI_QUOTATION_CREATEFROMDATA, to what extent is it possible to replicate this variant configuration. This BAPI does contain Tables like ORDER_CFGS_REF, ORDER_CFGS_INST, ORDER_CFGS_PART_OF, ORDER_CFGS_VALUE. But documentation abt these tables isnt available.

Any experience with similar situations?

Best Regards
