tree display

Former Member — Wed, 28 May 2008 05:48:01 GMT

i have two internal tables one is header and the other is line items connected by belnr.

now i want to display them as hierarchial list.

but at first only the header fields should be diplayed and a plus sign should be there below belnr.

when i click on that plus the line item for that header should be diplayed.

how cn this be done? ny example code?
