Changes don't reflect using BAPI_PROJECT_MAINTAIN through RFC adapter

Question

Hi,
I am working on a Integration Scenario in XI. In this I am executing BAPIs through RFC adapter. I am using BAPI_PROJECT_MAINTAIN to create WBS Elements in Project System. After creating WBS Elements when I try to define the hierarchy, the BAPI calls executes successfully but the hierarchy is not visible when viewed in the SAP WEB GUI.
I am using following parameters to define WBS hierarchy:
*IMethodProject
    OBJECTTYPE = WBS-HIERARCHY
    METHOD = CREATE
    OBJECTKEY =
    REFNUMBER =
    OBJECTTYPE =
    METHOD = SAVE
    OBJECTKEY =
    REFNUMBER =
*IProjectDefinition
    PROJECT_DEFINITION = P-0300-00-04
*IWbsHierarchieTable
    WBS_ELEMENT = WBS-001
    PROJECT_DEFINITION = P-0300-00-04
    UP =
    DOWN = WBS-002
    LEFT =
    RIGHT =
    WBS_ELEMENT = WBS-002
    PROJECT_DEFINITION = P-0300-00-04
    UP = WBS-001
    DOWN =
    LEFT =
    RIGHT =
In normal case the WBS element 'WBS-002' should move below 'WBS-001', but when I execute BAPI with above parameters, the Hierarchy is not visible in the GUI the both WBS Elements remain at root level, even I get '000' as response with no errors.
When I run the BAPI through transaction SE37 with same parameters as above, the changes are visible in the GUI.
Can anyone please tell what am I missing here.
Thanks & Regards,

Hi Ajay,
I understand the problem this way, when u do something thru XI you dont see the effect (even if the the transaction is successful), whereas when it done is directly in the R/3 you can see the output.
  look into the below
- check if your XI user is having necessary authorisations (you can do this by enabling the trace in ur R/3 - back end system)
- check if you are passing the input properly in the XI. (like field formats, padding characters, prefixes etc)
Hope this helps to fix ur issue
