ASSET relatd error

Hi, I am facing a problem here. For import purchase order an asset is there. For custom duty payment I am using MIRO transaction code .But the system is giving an error message and hence can not be posted.The system is giving following message :

Message no. AAPO176

Diagnosis

Transaction type 100 that you entered or the standard transaction type

which is specified for activity 'Acquisition from invoice receipt w/

affil. comp.' is not allowed. Reason: Differing Setting for "Post to

Affiliated Company".

Procedure

Check the standard transaction type specified in Customizing for

activity 'Acquisition from invoice receipt w/ affil. comp.', or check

the transaction type you entered.

Please suggest what is to be done
