Mapping related Issues

Hi all ,

I am working on IDOC-XI-xml file scenario . I am able to trigger the file properly

and able to receive it in XI .

But I am getting problems in mapping . The problem is as follows :

I did one to one mapping for WP_PLU02 idoc(Material Master) .

If there are <u><b>ten or more Material triggered in single IDOC</b></u> then How can we map it to our target data .

Can anybody share mapping example of multiple material master mapped to one data target .

Thanks & Regards
