Deliver To has different values at header and line-item level.

How does this field default at header level and the line level?

The Deliver To field at the header level defaults from the User Profile while the line-level field defaults based on information in your CEME (CommodityExportMapEntry.csv) file. If there is no value in the CEME, the line-level Deliver To also defaults from the User Profile.

You can also find more information regarding Deliver To defaulting in the Purchasing Guide for Procurement Professionals:

The defaulting behavior on Bill To, Ship To, and Deliver To fields are as follows:

The Bill To, Ship To, and Deliver To fields, along with other accounting fields, are typically defaulted from the master data that is loaded into the Ariba Procurement Solution, for all users and commodities. You can, however, override these values manually at header and/or line level when creating a requisition.

The Ariba Procurement Solution defaults the Bill To, Ship To, and Deliver To field values only initially. The defaulting mechanism is not triggered again if you have manually changed the values at any point when creating the requisition.

In particular, the Ship To and Deliver To fields are set as follows:

• If you change the header-level Ship To or Deliver To fields, then the Ship To and Deliver To is set to the header values on all existing line items on the requisition unless the you have previously modified the values at line level. Note: Line level changes take precedence over header level changes.
• If you have manually changed the line-level Ship To or Deliver To field from the initial default value, these manually changed values are not re-defaulted and can only be changed through an explicit user action. Subsequent edits to the line items will not trigger the defaulting mechanism to re-default the Ship To and Deliver To fields.
• Any new line items added to the requisition after you have changed the Ship To and Deliver To fields at the header level will then inherit the changed values.
