问题 I'm trying to call SAP functions from an Excel macro, VBA. I can do the connection, but whenever the code reaches the line that calls a function, I get the error message "Run-time error '61704': Internal application error. My code is the following: Dim functionCtrl As Object Dim sapConnection As Object Dim theFunc As Object Dim PoNumber Set functionCtrl = CreateObject("SAP.Functions") Set sapConnection = functionCtrl.Connection sapConnection.System = "" sapConnection.Client = "" sapConnection
