How to find reference document number for cross company sales.

Hi Experts,

I have created cross company delivery with reference to a PO using transaction VL10B. After creation if I check VBFA table for preceeding document number/reference number, I couldn't find my PO number. Please help me in finding out the preceeding document number i.e PO for a cross company delivery made using VL10B.
