Mapping Issue with Use One as many

Hi,

I have in source ORDRSP05 IDoc. The IDoc contains E1EDP02 & E1EDP20 as:

<IDoc>

   <E1EDP01>

             <E1EDP02>

             <E1EDP20>

The above structure is only for showing heirarchy & not a valid XML of course. Since I am mapping target parent segment with E1EDP20, I need to have use one as many for a field mapped from E1EDP02. This works fine when E1EDP02 comes once in one E1EDP01. However, it shows me error in Use one as many when I have two E1EDP02 within same E1EDP01 ie.

<IDoc>

               <E1EDP01>

                    <E1EDP02>

                    <E1EDP02>

                    <E1EDP20>

                    <E1EDP20>

                    <E1EDP20>

Thus, I need to have 6 outputs from Use one as many as each of two E1EDP02 will be triplicated. Will it be possible with standard mapping functions??
