SYMPTOMS
When you create a Microsoft BizTalk Server 2006 or Microsoft BizTalk Server 2004 script functoid that contains Microsoft Visual Basic .NET scripts or Microsoft Visual C# .NET scripts, or when the functoid links to an external assembly, you may not be able to add more than one inbound connection to the functoid in BizTalk Mapper.



CAUSE
This issue may occur when the functoid that you created contains scripts or when the functoid links to an external assembly that has an unknown number of parameters or a variable number of parameters.



RESOLUTION
To resolve this issue, configure the script in the functoid to use a specific number of parameters.
