Adding Header Line in CSV File - FCC Parameter Configuration

Hi Experts,

Need an urgent help on the below issue.

Scenario:We have IDOC to CSV File scenario. The message structure at the receiver end is as follows,

Header Details

        Field 1

        Field 2

        Intermediate details

                Field 3

                Field 4

                Item Details

                        Field 5

                        Field 6

Requirement:We want the all the field headers of Header Details, Intermediate Details & Item Details, get populated in the CSV file at the first line.

FCC Parameter Configuration:

Recordset Structure: Header Details,Intermediate Details,Item Details

Header Details.addHeaderLine: 3

Header Details.headerLine: Field 1,Field 2

Header Details.fieldSeperator: |

Intermediate Details.addHeaderLine: 3

Intermediate Details.headerLine: Field 3,Field 4

Intermediate Details.fieldSeperator: |

Item Details.addHeaderLine: 3

Item Details.headerLine: Field 5,Field 6

Item Details.fieldSeperator: |

Item Details.endSeperator: 'nl'

Issue: Even after making these changes, the generated output CSV file doesn't contain any such header line.

Thanks in advance.
