-1120 - Ref count for this object is higher then 0

I get this error when adding an object from XML, however if I run the exact same code again on the application it works?

Anyone experienced anything like this?

Hi Daniel,

This error normaly occurs when using metadata objects. (When adding tables and fields and UDO's). SBO only allows 1 connection to such an object. I don't know what you are attempting to do, but it's always "wise" to kill objects that you are finished with before instanciating new ones (saves on memory etc.). Thus I will show you what I do and maybe if you are more specific in creation and killing of objects your problem will be solved. My demo is in VB .Net.

'1. Add a table using SAPbobsCOM.UserTablesMD object

Dim oUTables As SAPbobsCOM.UserTablesMD

'Create Instance of UserTablesMD object

oUTables = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserTables)

'Add the table code .....................

'NOW to KILL the object

' IMPORTANT: Only one (“handle to a”) user table or field object should be alive

' at one time!!! -> In .NET call this first

System.Runtime.InteropServices.Marshal.ReleaseComObject(oUTables)

'Then set object variable to Nothing…

oUTables = Nothing

GC.Collect() 'Call the garbage collector for good measure

'2. Add a field using SAPbobsCOM.UserFieldsMD object

Dim oUFields As SAPbobsCOM.UserFieldsMD

'Create Instance of UserFieldsMD object

oUFields = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserFields)

'Add the field code .....................

'NOW to KILL the object

' IMPORTANT: Only one (“handle to a”) user table or field object should be alive

' at one time!!! -> In .NET call this first

System.Runtime.InteropServices.Marshal.ReleaseComObject(oUFields)

'Then set object variable to Nothing…

oUFields = Nothing

GC.Collect()

TRY THIS - MAYBE IT WORKS FOR YOU...

Hi Barend,

Indeed you are correct, I am working with userfields. I have implemented the code you suggest and have not experienced the error again!

Thanks very much for your post, and Merry Christmas

It is also nice to know:

It is a condition for the usage of

Dim oUDT As SAPbobsCOM.UserTablesMD

oUDT = oDataIterface.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oUserTables)

...

that all other BusinessObjects must be closed.

Example: Global hold BusinessObject-References

otherwise "-1120 - Ref count for this object is higher then 0"-Message arise!
