• Vendor Perf. Header: Copies current PO data

• Receive PO
• Purchase Header Archive: Copies current PO Data before receipt
• Purchase Line Archive: Copies current lines before receipt
• Vendor Perf. Header: Updates using current PO data after receipt
• Vendor Perf. Line: Updates using current PO Lines after receipt
• For Lines changed to 0 order qty, Vendor Perf. Line will record a 0 qty receipt at the current receipt date
• Any line with 0 receipt qty, but with a receipt date represents a cancelled line
• Add New Lines to PO
• Vendor Perf. Line: Copies new PO Lines
• Invoice PO
• Vendor Perf. Header: Updates using current PO data after invoice
• Vendor Perf. Line: Updates using current PO Lines after invoice

In English, this means

• PO is archived only when received
• Vendor Fulfilment uses the original numbers on PO Lines when the release button is pressed the first time.
• If a new line is entered, the next time the release button is pressed, that line is added to the Vendor fulfilment calculation
• Vendor fulfilment will NEVER be affected by any future changes to the PO
• When the PO is Received or Invoiced, Vendor Fulfilment lines are updated with receipt and invoice information only. The original Recorded PO amounts at the time of releasing the PO do not change in the Vendor Fulfilment calculations.
