File Handling in BODS - Row Markers

Hi,

Is there any way in BODS to ignore file trailer directly? I am using BODS 3.2.

In my requirement the header and trailer records cannot be identified by a particular row marker? In this case "ignore row marker" cannot be used.

Also, can we use variables in ignore row marker?  I want to pass a 20 character long string in that variable to ignore from loading.

Please suggest

Thanks,

Akhilesh
