• It works only in an EDI environment.

• Reports provide information from one level to another for EMT purchase orders and sales orders, but not across multiple levels.

• Credit flow can cross only one level.

• Configured items must have the same configuration across all levels within the supply chain.

• Change management is communicated level by level, one level at a time for some changes, and automatically for other changes. For example, a change at level 1 is automatically accepted at level 3 unless the order is picked, released to a work order, or shipped. If a change made at a lower level is rejected by an upper level, the orders are compromised and must be resolved manually.

• ASNs are processed through the original supply chain. For example, an ASN cannot be processed from a level 3 site directly to the end customer.

• If there is an error creating the secondary sales order at a lower level, the originator of the purchase order must open a new PO with correct data and reexport it.
