It was an intresting finding.
Generally when we work with collective order we some times face issue in the inconsitency between the reports COGI & CORUAFFW.
Few orders which are displayed in the CORUAFFW report will not be available in the COGI report.
when such situation arises one solution to be tried is as below.
1. Implement the SAP Note Note 513786 – Dependent goods movements are separated
2. This report will implement a report Z_DEL_REFBLN
3. This report helps you to find the inconsistent orders in test mode and later you can run in the update mode.
4. Once this report is executed in update mode for the affected production orders , then you can see the same details in the COGI report also.
