Hi all

please help me.I have to display values in tree view form based on the one input value called partner number.using this partner number i have to search a table zrelation and all the dependent relativ numbers on this partner should be displayed under this partner.If these dependent numbers are independent then no problem otherwise i have to display the numbers which or dependent on these relation numbers.Please help me to do this.

Thanks in advance.
