Receiver File Adapter - Tab delimited Text file

I am using receiver file adapter to convert message created by ABAP PROXY to convert tab delimited text file format.

XML message is in following format.

- <DT_R3_ROLES_OUTBOUND_REC>

<LIST_CATEGORY>SAP_HR</LIST_CATEGORY>

<USRID>MRUDULAP</USRID>

MRUDULAP@ABC.COM

<NAME>MRUDULA PATEL</NAME>

</DT_R3_ROLES_OUTBOUND_REC>

- <DT_R3_ROLES_OUTBOUND_REC>

<LIST_CATEGORY>SAP_HR</LIST_CATEGORY>

<USRID>HCHD</USRID>

HCHD@ABC.COM

<NAME>H CHD</NAME>

</DT_R3_ROLES_OUTBOUND_REC>

I have used file content conversion in the adapter configuration.

Recordset structure = DT_LISTSERV_INBOUND_REC

DT_LISTSERV_INBOUND_REC.addHeaderLine = 0

DT_LISTSERV_INBOUND_REC.fieldSeparator = ','

How to use Tab as the delimiter in the fieldSeparator field?

Now the output in the file is as follows :

MRUDULAP@ABC.COM'MRUDULA PATEL

HCHD@ABC.COM'H CHD

What I need to do to make the file as the tab delimited file?

Thanks in advance!
