-
BizTalk Adapter Pack 2010
Symptoms
Consider the following scenario:
-
You install Microsoft BizTalk Adapter for mySAP Business Suite 3.0 on a computer.
Note BizTalk Adapter for mySAP Business Suite 3.0 is included in the Microsoft BizTalk Adapter Pack 2.0 or in the Microsoft BizTalk Adapter Pack 2010 . -
The WCF-SAP adapter executes a remote function call (RFC) or Business Application Programming Interface (BAPI) to an SAP system.
-
The SAP system returns a negative decimal value of the RFC_BCD data type.
In this scenario, you may receive an error that resembles the following:
The formatter threw an exception while trying to deserialize the message:
There was an error while trying to deserialize parameter http://Microsoft.LobServices.Sap/2007/03/Rfc/:EXPHEADER.
The InnerException message was 'There was an error deserializing the object of type microsoft.lobservices.sap._2007._03.Types.Rfc.BAPIMEPOHEADER.
The value '-*<decimal value>' cannot be parsed as the type 'decimal'.'
Cause
This issue occurs because the RFC_BCD value is converted to the .NET String data type incorrectly.
When the RFC_BCD value is converted to the .NET String data type, the WCF-SAP adapter does not allocate enough memory locations to convert the value. Therefore, an exception is encountered.
