Sructure is "Partly Active" . How to do "Active" ?

Hi,

We enhance the structure CRMT_MKTLIST_PER_EXT by adding new filed in the append structure. But the status of this structure is "Partly Active".

We tried to change this using SE14 , but is giving "Object CRMT_MKTLIST_PER_EXT cannot be processed via DB utility".

Pls tell me how to change the status to 'Active'.

Thanks.
