Local Currency is not maintained

Hi guys,

I've done transfer posting (mvt type 301) and this error message was popped out

"Local currency of cons unit XXXX-1234 is not maintained"

and the diagnosis is :

"the master data of consolidation unit XXX-1234 does not show a local currency"

Why did this error message happen? and what steps do I need to config the currency? Kindly need your help to solve this issue.

Thanks and Regards
