3773257 - Timeout error when creating supplier confirmations for large purchase orders in Manage Supplier Confirmations (F5039) - SAP S/4HANA Cloud Public Edition

• Creating a supplier confirmation for a purchase order with many items in the app "Manage Supplier Confirmations" (F5039) results in a timeout error.
• The supplier confirmation cannot be created when the purchase order contains a high number of items.
• In some cases, Quick Create is blocked if a supplier confirmation draft already exists for the same purchase order.

SAP S/4HANA Cloud Public Edition

1. Open the app Manage Supplier Confirmations (F5039).
2. Choose Quick Create.
3. Enter a purchase order that contains many items (for example, more than 200 items) and proceed.
4. Observe that the operation ends with a timeout error and the supplier confirmation is not created.

• Large purchase orders significantly increase processing effort during supplier confirmation creation, especially when the confirmation control key has the “adopt price change” flag enabled (order acknowledgement step). This triggers price recalculation and purchase order updates for many items, causing performance bottlenecks that can lead to timeouts in the UI.
• If a supplier confirmation draft already exists for the same purchase order, Quick Create cannot proceed; drafts are user-private and not visible to other users until completed or discarded.

1. Review confirmation control settings (SSCUI 101718 – Set Up Confirmation Control). If the “adopt price change” flag is enabled for order acknowledgement and Quick Create uses the same prices as the purchase order, consider disabling the flag to avoid unnecessary mass price recalculation during confirmation.
2. If price adoption from confirmations is required, activate Flexible Workflow for Supplier Confirmations (SSCUI 105632) with automatic approval. This shifts the purchase order update (including price adoption) to the backend, where longer processing windows reduce UI timeout risk.
3. Ensure no existing supplier confirmation drafts block creation. Ask the draft’s creator to complete or delete the draft. Note that drafts are typically visible only to their creators and are automatically discarded after a retention period.
4. Avoid very large or complex purchase orders where possible. Split into smaller documents and limit one-to-many expansions (for example, numerous schedule lines or multiple account assignments) to improve performance and prevent timeouts.
