Duplicated field was not appearing on mapping(test tab)

Hi All,

I have one requirement in mapping level.

Requirement: At sender side(File) i have two different fields and receiver side(IDOC) having only one field. These two fields data should go to receiver field.I have created a Duplicate for the same filed(C) and Mapped accordingly,but while doing testing in mapping level the field is presenting only one time at target side, but i need two times that same field should represent under the same node.

Please suggest me with your helpful answers.

Regards,

Kumar
