Hello BPE,
Now it has been established that the issue is a technical one. You developer must be testing various things and did not transport to other clients, and hence the difference in DEV and QAS. Also these field were not available upto EHP0 which is mine. So. now it will become local issue, meaning that you need to find the reasons and solutions working in collaboration with your own ABAPer.
Good luck
