Exception when creating project using RFC /.NET connector

[Former Member]

Hello All,

I am trying to create a project plan in SAP using .net connector 2.0. After putting in all the values and verifying that the requested parameters are supplied, i call an RFC. But it raises an exception

"

An unhandled exception of type 'SAP.Connector.RfcSystemException' occurred in sap.connector.rfc.dll

Additional information: Please assign investment prog to WBS

"

Here is more information about the process.

Please let me know what I am doing wrong or where I can find more information about this. I am not the one doing the RFC, I was just told how to call it. It seems to work fine when tested through SAP Logon.

More info:

Dim failTBl As New BAPIRETURN1Table

Dim successTBl As New BAPIRETURN1Table

Dim mspObject As New ZPROJ_INPUT

Dim mspObjectTable As New ZPROJ_INPUTTable

Dim cs As String = "blah blah....

Dim mspProxy As New SAPProxy1(cs)

'populate the mspObjectTbl with all the rows

'and then call the rfc

mspProxy.Zbapi_Project_Create_Msp("X", "X", "X", "X", "X", mspObjectTable, failTBl, successTBl)

The X bascially mean do the tasks:

1. check if porject already exists

2. create project

3. create wbs

4. create network

5. create activity

The mspObjectTable contains the project plan in the form of rows.

The failTbl contains all messages of the actions that failed

The successTbl contains all messages of the successful actions.

Am not sure am in the right category. If not, moderator please help me to movve it.

Am also not sure if this helps, but here is the autogenerated code when an RFC is dragged into the sapproxy

The exception points to

results = SAPInvoke("Zbapi_Project_Create_Msp", new Object() { _

Zact_Cre,Znet_Hdr_Cre,Zproj_Exist_Chk,Zwbs_Cre,Zwbs_Hry_Cre,Zproj_Input,Zreturn_Fail,Zreturn_Success })

Thanks
