SAP ALV Tree fieldcatalog creation

The following ABAP code and information is part of the example ALV tree report demo and create a field catalog for an ALV tree report. See main program to see how this code looks within the completed program.

It is much the same as creating one for a standard ALV report, just note the structure of actual fieldcatalogs internal table as it may be different to what you have been using depending on which method of ALV report you have been developing i.e. LIST, GRID or OBJECT version.

Also see here for other ways to create fieldcatalog 

----Add to START-OF-SELECTION Event
* Create fieldcatalog for ALVtree report
  PERFORM build_fieldcatalog.
----Add to main prog after START-OF-SELECTION Event
* Build Fields Catalogue

form build_fieldcatalog.
* Please not there are a number of differences between the structure of
* ALVtree fieldcatalogs and ALVgrid fieldcatalogs.
* For example the field seltext_m is replace by scrtext_m in ALVtree.
