A Pre-Approved document does not show up as supply. A Pre-Approved document is one that meets the following conditions:
A person with the final authority to approve the document approves it, but then forwards it to someone else for additional approval, thus changing its status to Pre-Approved.
Your organization uses encumbrance (reserves funds for documents), and the document is authorized for approval but funds have not yet been reserved for it. Even if someone with sufficient approval authority approves the document, its status may still be Pre-Approved if funds were not able to be reserved at the time of approval. Once funds are reserved for the approved document, the document changes its status to Approved.
A Pre-Approved document does not show up as supply until its status changes to Approved.
When you make a change to an approved document that changes its status to Requires Reapproval, that change (for example, to quantity) does not show up as supply until the document has been approved again.
Approved requisition lines that have a line type based on rate or fixed price do not show up as supply.
