3627886 - Limitation for optimum performance of Manage Purchase Order app in SAP S/4HANA Cloud Public Edition

You are experiencing performance issues when processing purchase orders with a large number of items in the Manage Purchase Orders app in SAP S/4HANA Cloud Public Edition.

SAP S/4HANA Cloud Public Edition

The performance of Manage Purchase Orders is influenced by various factors, including system settings, configurations, available resources, and the complexity of the purchase order (e.g., number of entities used or use of logic-intensive fields).

However, regardless of how well these factors are optimized, creating and processing purchase orders with a large number of line items will inevitably lead to performance challenges in a standard SAP system.

SAP recommends avoiding purchase orders with a high number of items. Based on the factors described in this KBA, and depending on the complexity of a purchase order, internal performance tests have shown that, in some cases, performance can decline when processing orders with more than 200 items—or even with fewer items. A purchase order is considered complex if it contains many items branching off into many entities, even more so with one-to-many relationships. For example, if each of the items has many schedule line entries or uses multiple account assignment. In addition, the approval workflow of a purchase order should be configured properly, if it is used. Working with documents containing thousands of items may result in severe performance issues, including delays, timeouts, and difficulties managing document history—especially as follow-on documents are created for each item throughout the business process.

If large documents are unavoidable for business reasons, consider splitting them into smaller purchase orders wherever possible. This facilitates better performance and manageability throughout the document lifecycle.

Please note that there are also technical constraints within standard SAP processing for large documents (e.g., limitations in the number of invoice items that can be processed simultaneously).
