Recently I came across an error :
The function is not possible because the data structures are not active in operating concern, and observed some weird SAP behavior in activating the data structure, so just want to share the observation and resolution to solve it both.
1. Assuming you have configured the Characteristic and Maintain value fields.
2. Maintain Operating concern after configuring the data structure in data structure: Characteristic screen, you click on activate and dont save it, just go back SAP will prompt you for "Do you wish to generate the operating concern environment" click yes, you operating concern would be activated successfully and green light will make you happy.
But if you click on activate and save it and then go back it will keep on buzz with error " The function is not possible because the data structure are not active)
Hope this might help some one who stuck at client side.
Thanks
