n*tree

How to enter the general data in a n*tree structure

What to do:

Select Manager > Tools > N*tree.
The form N*Tree definition is opened.

Change to Insert mode and enter the structure name, e.g. ITEM-COMPLETE.

As the structure ITEM-COMPLETE is a higher structure to be execute, a mask name shall be entered. (See Userexit documentation xntree_wlk)

Enter the mask name in the field mask name of the mask to be started by the function n*tree, e.g. EDB-ART-SLI

Enter the userexit in the field Pre-structure processing which is to be processed before other structures are to be processed.
In this example the data is reserved by the LogiView Userexit EP_NTREE/ExportRecord for the loader file.

Fill in the field post-mask userexit.
This userexit is processed before the mask is closed.

Please remember that the LogiView userexit is called with the instruction lgv_nosel_run("Logic model/Decision table") .
In this example this instruction is lgv_nosel_un("EP_NTREE/FinishExport") which asks for the name of the loader file.

Repeat the above steps to create the following subordinated structures.
Please fill in the specified fields. The field Memo can contain any comment.

Structure name:	ITEM-STRUCTURE
Start Userexit:	iwf_lis_ref("EDB-ARTICLE STR")
Pre-structure processing:	EP_NTREE/ExportRecord

Editing a part tree

n*tree aborts the processing of a branch if the userexit specified in the pre-structure processing returns an error message. (Demanded/Defined cancel condition in the userexit).
