Re-initializing the delta queue is a time-consuming, resource-intensive activity, but it is necessary to maintain the data integrity and accuracy of information. Follow step-by-step instructions for an alternative process that avoids the re-initialization, yet maintains the data integrity and accuracy of information.
Key Concept
The delta queue is a data store in the source system into which data records are written in the form of Logical Units of Work (LUWs). Use transaction RSA7 to view the data in the delta queue.

When you have corrupt data, delta loads may fail in the source system during extraction. To address the complex problem of corrupt data, the most common solution is to do a complete re-initialization of the data. Completely re-initializing the data, though clean, has several disadvantages, such as it requires a significant amount of time and effort and system downtime. This downtime has financial repercussions in terms of data availability as well as the inability to post transactions during lengthy downtimes.

A quicker and less resource-intense solution to address corrupt data is to use the information the TIDs supply. (If you are unfamiliar with TIDs, refer to the sidebar “Understanding the TID.”) Because every purchase order has a corresponding TID, you can identify and segregate the corrupted purchase order data by displaying the delta queue using transaction RSA7. Identify the corrupted records by looking up the contents of the delta queue. Change the display variants to select Host ID, Process ID, Time, and Counter fields.
