You have set the data file autoextend to YES but when you checked from transaction code DB02, the status still showing NO.

Solution
1. Refresh / update the data for transaction code DB02. To do this, execute transaction code DB02 and press F8 (or click on Refresh icon). Wait till the process completed and you will see the latest output.

2. If the step 1 not working, check the value maintained in size & maxsize on previous tablespace extend. You can find the value by referring to this article, Tablespace Extend with SAP BRTOOLS – the value is at step 7. If the value of size & maxsize is same, the autoextend status will show NO. To cater this, in future, when you do the tablespace extend – you need to fill the value of maxsize greater than size. Then, the status will be YES.
