Three includes need to be created in-order to store the ABAP code required for the ALVtree report.
Typically these will be one for the PBO modules, one for PAI modules and one for the subroutines(FORMs):
*Includes
include zdemo_alvtreeo01. "Screen PBO Modules
include zdemo_alvtreei01. "Screen PAI Modules
include zdemo_alvtreef01. "ABAP Subroutines(FORMS)
If you are using the code provide within the ALVtree section of this web site simply create the includes by
un-commenting the 'Includes' section within the code(see below) and double clicking on the name
i.e. 'zdemo_alvtreeo01'. Obviously these can be renamed.
