Issues loading Flat Hierarchy File for Loading (PSA)

Hello Experts

What does it mean when you I load a hierarchy through a flat file:

1. I am able to upload the file and under Monitor, I can see the Hierarchy structure but when I can’t see it when I access the Hierarchy under the InfoObject on which I created the hierarchy?

2. What do you specify in the flat file to address the issue of duplicate nodes

3.When one node in a hierarchy is time is time-dependant, how do you specify it in a when loafing the hierarchy through a flat file?

4. What exactly is a “sorted hierarchy” and what is its significance? And how do you specify it when loading the hierarchy through a flat file.

5. What do I do, if I want NodeX to be loadable (i.e. to make it possible to load data to NodeX ) but make NodeY unloadable?

Thanks in advance.

    Hi Amanda,

    1. You can see hierarchy structure (as it should be in the flat file for upload) with particular nodes to be uploaded in Infopackage simulation (in case of iDoc methos).

    The hierarchy structure (without data) you can see in Datasource tab of transfer rules.

    In Infoobject maintenance you can see already loaded/created hierarchy.

    2. If you mean link nodes, then you have to follow rules for link nodes creation.

    3. If an hierarchy is time-dependant you’ll have to provide in the file 2 additional fields DateTo and DateFrom.

    4. The difference between sorted and unsorted hierarchies you can see in Datasource tab of TRs – click ‘Hier. Structure’ button. Check/uncheck ‘Sorted Hierarchy’ button and watch which fields appear/disappear in/from the structure. The prompt - for sorted hierarchy you have all set of node IDs: parent, child, next. For unsorted hierarchy you have ParentID only.

    So, if you load data from a file for unsorted hierarchy the system may take care of sorting child nodes.

    In case of sorted hierarchy you determine which node will follow which one.

    I’m may be mistaken, but I think that this Sorted Hier. feature effects only data load from files. BEx properties for hierarchy, IMHO, overwrite it.

    5. I think you mean here postable and non-postable nodes and leaves. In general, postable ones represent the basic hierarchy char, non-postable – text nodes and external char nodes:

    Best regards,
