Error while activating the BSEG table

hi guys ,

today i joined SAP SCN . I have this error

First i appended a structure of 5 fields in BSEG table .Then i tried to delete this append structure.

But while deletiing it took nearly 20-25 minutes to process and timed out.So the structure is deleted

from BSEG table but those 5 fields are still present in view V_QCMBSEG .Because of this BSEG table

is now partially active .what should i do other than access key .
