Retrieve information Parent-sons

[zied_ahmed1]

Hello Guys 

I have an excel structure like this : 

Field One                      Field Two 

256836	........113578.524113.115256.256836
N38402	.......113578.524113.115256.256836.N38402
N61755	.......113578.524113.115256.256836.N61755
N89028	.......113578.524113.115256.256836.N89028
N00674	.......113578.524113.115256.256836.N00674
N14190	.......113578.524113.115256.256836.N14190
191429	.......113578.524113.115256.256836.191429
N40602	.......113578.524113.115256.256836.N40602

If you see the 255836 is the parent of all the other fields 

So I need for example when i select in Qlik the 255836 i will have directly a new field with his sons :

Something like this  : 

255836 ---->  N38402

                          N61755

                          N61755

                          N89028

                          N00674

                          N14190

                          191429

                          N40602

(This is just an example I need to Apply that for others examples (if there is a value in the right of the Field One he is his son ))

Thank you
