how do i copy a secondary data source into main data source without using code??

This functionality is not built into InfoPath, but qRules 1.5 will allow you to do it.  I recommend having a look:

On tyour track, I am having trouble with down loading the qrules,
  I think I need Windows XP professional. I only have XP home edition.

my main source structure is like

<Categories and responsibilities>

<Categories>(GroupNode repeating)

<catelement></catelement>

<responsibilities>(GroupNode repeating)

<respelement1></respelement1>

<respelement2></respelement2>

</responsibilities>
