Journal Import appending Source, Actual Flag,Group ID,Request ID to Batch Name

Hi

I have a requirement to import Journals from 11i to R12, along with the 11i Batch Names.

I am passing a Batch Name to GL_INTERFACE.REFERENCE1.

Journal import is successful but adding Journal Source, Actual Flag, Group ID and Request ID

I found This

REFERENCE1 (Batch Name): Enter a batch name for your import batch. Journal Import creates a default batch name using the following format: (Optional User-Entered REFERENCE1) (Source) (Request ID) (Actual Flag) (Group ID). If you enter a batch name, Journal Import prefixes the first 50 characters of your batch name to the above format.
