Hi,

I'm trying to execute the fm BDS_BUSINESSDOCUMENT_CRE_O_URL via RFC but always get the following error:

com.sap.conn.jco.AbapException: (126) ERROR_DP: ERROR_DP Message 027 of class SBDS type W, Par[1]: 1
	at com.sap.conn.jco.rt.MiddlewareJavaRfc$JavaRfcClient.execute(MiddlewareJavaRfc.java:1875)
	at com.sap.conn.jco.rt.ClientConnection.execute(ClientConnection.java:1120)
	at com.sap.conn.jco.rt.ClientConnection.execute(ClientConnection.java:953)
	at com.sap.conn.jco.rt.RfcDestination.execute(RfcDestination.java:1465)
	at com.sap.conn.jco.rt.RfcDestination.execute(RfcDestination.java:1435)
	at com.sap.conn.jco.rt.AbapFunction.execute(AbapFunction.java:300)


If I try to execute the fm in SE37 with the same values, it works fine. Can anyone tell my what this error message mean? I just find that might be a "data provider issue". So I assume it's related to my Java code?

Attached is the class that I'm using.

Does anyone know or see what I'm doing wrong?package com.company;

PS: I'm not able to add the Java code as TXT attachment (even TXT seems to be allowed to add...) It says: This attachment is not permitted because the file type is invalid.
