In some cases, the outbound delivery remains in “Picking Completed” status, while the Post Goods Issue (PGI) is still pending. There are no obvious error messages, and it is difficult to determine whether the issue is related to SAP EWM configuration, PPF actions, queues, or SAP S/4HANA integration.

I would like to understand the complete troubleshooting process.

Please help with the following points:

• What is the complete Goods Issue (GI) process in SAP EWM?
• What are the prerequisites for posting Goods Issue after warehouse task confirmation?
• Why does Goods Issue remain pending even though picking is completed?
• How do PPF actions affect automatic Goods Issue posting?
• Can warehouse process type, document type, or item type prevent Goods Issue?
• How do qRFC queues and SAP S/4HANA integration affect GI posting?
• Can open warehouse tasks, handling units, serial numbers, or delivery status block Goods Issue?
• Which transaction codes and /SCWM/MON nodes should be checked during troubleshooting?
• How can we identify whether the issue is in SAP EWM or SAP S/4HANA?
• What are the most common error messages during Goods Issue posting and how can they be resolved?
• Can someone share a real-time project example with step-by-step troubleshooting?

A detailed explanation with configuration paths, transaction codes, application logs, debugging tips, and practical examples would be very helpful.
