Could you please paste the code in wdDoInit method of your controller? From the statck trace it looks like the error is occurring at line 106 (SalesOrderComp.java:106). Please double check what you have at this line and see if it is correct. If any additional parameters are added to the RFC after the application is deployed and run once, you need to restart the server to refresh the rfc metadata.

Thanks

Hi,

Write these statements in wdDoInit() method

Z_51Vj_Rfc_Salesorder_Entry_Input eInput = new Z_51Vj_Rfc_Salesorder_Entry_Input();

wdContext.node<RequestNode>().bind(eInput);

Hi,

I don't think the null pointer exception would be on the line mentioned by you. Could you please check the stack trace and give us the line which is resulting into null pointer exception.

hi,

You have to bind thisobject to the context..

put the follwing code in the init() of your controller after declaring the object;

wdcontext.node<...>.bind(eInput);
