Partner functions OA and IP missing for Vendor in Extended classic PO
As part of current Classic scenario, we have maintained OA (Ordering Address) and PI (Invoicing Party) for a vendor in R/3. We have also maintained different ordering addresses for multiple plants in the Vendor master: Partner functions screen --> Alternative data.
I would like to acheive the same functionality in Extended Classic scenario. We have replicated the vendors from R/3 to SRM. After activating Extended Classic scenario, we see only VN as the partner function in R/3 PO.
Q1. How can we enable OA and PI partner functions in R/3 PO (Extended Classic) ?
Q2. How can we enable different ordering addresses for multiple plants in R/3 PO (Extended Classic) ?
