Issue:

The general posting process finalizes the documents and then creates the corresponding entries. Preview Posting follows the same workflow; however, the entries are simulated rather than actually posted. Despite this difference, the underlying posting logic is largely the same.

Example:

Currently, the posting design can become a bottleneck when processing large volumes of data. For example, in the warehouse shipment scenario, Preview Posting processed approximately 600 sales orders to generate warehouse shipment lines. Due to performance constraints during the numbering process, multiple warehouse shipment lines were assigned the same number, leading to data conflicts that ultimately caused the process to fail.

Recommendation:

Enhancing the posting logic to improve performance in high-volume scenarios would be beneficial. Such improvements would not only help warehouse shipment processing but could also provide broader benefits across other posting-related processes throughout the system.
