Security_xpo import in AX 2012

Hi,

While importing security.xpo in AX 2012 , error showing ''Privilege MI_INDENT could not found''

Note : MI_INDENT is a customize form and available in security.xpo . but In a target system it is not available .

Is this fine if I ignore this Error , because the other customize roles and duties are importing properly.  I am doubt only if later some feature of the system or forms show errors ?
