To trim the data from a fix length

Hi Experts,

     I have a requirement in which i need to post the data from a particular character count.

For e.g.:

If the input is like :

distributed update operation failed; rollback required.Invoice date in the future is not allowed at COALXL.WATCH_STL_INVOICE_HDR, line 245 error during execution of trigger 'COALXL.WATCH_STL_INVOICE_HDR' at line 8.

Than i need to send the output like

COALXL.WATCH_STL_INVOICE_HDR, line 245 error during execution of trigger 'COALXL.WATCH_STL_INVOICE_HDR' at line 8.

Means it should truncated from a fixed position and then till the end.

Can you please suggest how can we do this?

Regards,

CB
