Mapping Error

Hi All,

In BizTalk map 2009, i have a output file error.

I have an input file, which i insert it and test it.

When the output is generated, i get the tags of destination schema which have not been supplied in the input file.

Note : The destination schema nodes which are appearing are mapped and its optional field.

I need to have the output XML which should not have fields, which were not provided by input file.

Kindly help me here
