Bin Allocation : Attempted to read or write protected memory

Hi All,

I am testing with the BinLocation features in a document.

I tried to do  an Inventory Good Receipt using below code :

SAPbobsCOM.Documents oGR = oC.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oInventoryGenEntry) as SAPbobsCOM.Documents;
oGR.DocDate = DateTime.Now;
oGR.Lines.ItemCode = "A00001";
oGR.Lines.Quantity = 1;
oGR.Lines.WarehouseCode = "UGWSG";
//SAPbobsCOM.DocumentLinesBinAllocations oBin = oGR.Lines.BinAllocations;
oGR.Lines.BinAllocations.BinAbsEntry = 81;

But as soon as I reach the BinAllocations object (either line 6 or 7), the system will throw an error :

Attempted to Read or Write protected memory. This is often an Indication that the other memory is corrupt.

It seems that I cannot access the object at all.

Anybody has any idea about this ?

Or anybody has make it to work with BIN allocation in SBO 9 PL5 ?

My system is :

Windows8 64bit,

SBO Client 32bit + 64bit installed. But for this testing only 32bit is running,

SQL Server 2012,

VS2012 Compiled in x86.

Regards
