Are the orders CLSD?
Try this:
1. Revoke the Deletion Flag.
2. Set TECO
3. Run CJEN
4. SET CLSD
5. Reset DLFL, but it's not really needed.
Deletion Flag is used as part of the archiving process.
The usual status flow is CRTD -> REL -> TECO -> CLSD
When you are ready to run archiving you can set DLFL.
