Subcontracting case with Source Location in P/DS

Hi, Yes, Production version being created on plant level and the header being not created on vendor location, (only component created on vendor location), I did not though to find the PPM there .... Thank you very much Other question but may be I have to create an other question ? I have seen that the stocked component ( delivered to subcontractor to deliver the hearder product) are CIFed to the plant location . I expected it to be rather CIFed to vendor location since immediate replinishment takes place on vendor location, I imagine the User exit on stock has to be used to get the stock on vendor location
