how can i install EDI standart set up file ? and where i can get this standart file to install on ERP LN?

You don't indicate an ERP version. For ERP LN the following help is present on session Import EDI Data (ecedi6220m000):
Use this session to import the predefined data used to process EDI messages. This data comes from the defaults.edi file, that can be exported from the demo company, or from another company. This session uses the defaults.edi file from the directory specified in the Standard Path field in the EDI Parameters (ecedi0100s000) session.
I am not sure on the location. Look for the defaults.edi file on your ERP server.

Check this site out for latest defaults and useful info.
