BAI2 Lockbox file - Load Import Process run to Error

Summary:

Trying to load BAI2 lockbox file filename "Arlockboximportbai2_12202024.dat". Load Interface process end in error with error message " Processing Data File: Arlockboximportbai2.dat Data files cannot be processed due to incorrect file name prefix. You must provide the Data Files having valid file prefix . Example: <<Valid File Prefix>><<Custom Text>>.csv

What does this mean. I thought BAI2 lockbox file has to be in .dat format with prefix pointing to specific transmission format and this file should be zipped and then loaded. Am i missing anything ?
