Vendor product relation not transfered from ECC to APO

Hi,

I am new to APO.

We are transferring the info records(me13n)  details from ECC to APO by CIF .

But in APO system , when I check the product for the location(/sapapo/mat1)  it says the product is not created for vendor.

but this details are present in info records in ECC.

Hence currently, we are manually creating the products for vendor.

Is there any BADI where all vendor-product link can be transferred
