User Default Settings
As a configuration expert, using the Default Settings for Users - Purchase Requisitions app, you can assign default values such as plant, company code, account assignment category, and cost center for purchase requisitions that are created by employees so that they don't need to enter the values manually. You can also choose custom document types from the list of purchasing document types.

To set the default values for several users, you can use the Excel-Based Data Exchange option. You can download the template, fill in the default values for multiple users, and upload the file. The SAP S/4HANA Cloud system then assigns and uses these values as default when the employee creates purchase requisitions. When uploading the user settings and catalog information using the Excel-Based Data Exchange feature, you can set a procurement catalog as the default for a user.
Note
As its name implies, the Default Settings for Users - Purchase Requisitions app is intended for use with purchase requisitions only. Therefore, values are set only when creating purchase requisitions. It does not affect the default settings or values when creating a purchase order or contract using the corresponding apps for the same user.As an employee, you can also set some of the default values to be used for your purchase requisitions using the My Purchase Requisitions – New app.

PO Price Type can take one of the following values:
Do not adopt: the price of the purchase requisition item is not adopted in the purchase order item.
As gross price: the price of the purchase requisition item is adopted in the purchase order item as the gross price.
