need inputs for ILM BW

Hi All,

i need some inputs from ILMBW team , once we installed all the BW Virtual provider from ILM BW SYSTEM by RSORBT t-code.

as we can see all the standard Virtual inforprovider in rsa1 and its related objects after installing. for bw reporting

1.) Now my question is how we load the data to Virtual provider which way is better to push the data, to VP , via bapi, or dtp, do i need to create?

2.) team is trying to push EX: FI BSEG table data by creating Audit Package, as they  Are facing some issues to create audit package for bw reporting, but they are success at local reporting to show the reports but issues with bw reporting while creating audit pacakge.

Pls let me know the solutions for this asap

Awaiting for the reply

Regards
