Which method can you use to initiate source determination during the manual creation of a purchase requisition?

Initiating source determination during the manual creation of a purchase requisition can be effectively done by using the button to Assign Source of Supply in the respective item. This approach allows for a targeted selection of a supplier for that specific item, facilitating a more precise sourcing process.

By using the item-specific button, you can evaluate different suppliers or sources that meet the requirements for that particular requisition line. This method ensures that the source determination process is tailored to the characteristics and needs of each item rather than applying a blanket source across the entire requisition.

The other options either suggest broader approaches that may not effectively manage the sourcing for individual items or involve settings that apply universally, which might not provide the level of specificity required when handling varied items within a purchase requisition.
