"E" stands for error. Check the input parameters you are passing to SAP to make sure you set all parameters correctly. Additionally, you can test the Function Module directly by setting the same data that you try setting through JCo and then see what happens.
Under "Message" in the return table, you should be able to see a more detailed reason for the error.
