Getting the fields from RFC model

[Former Member]

Hi,

We have a function module called Z_HR_ESS_PA0003 in backend system which is used to grab the field called AccountTo from infotype 3. I tried to fetch this field to do some validation in ESS banking but failed. Could you suggest what I did wrong in the following steps.

1. I created a model to import Z_HR_ESS_PA0003 function module.

2. I added this model in Used Model

3. I did the comtext mapping of Z_HR_ESS_PA0003_Input between custom controllers and used model and between detailedView and custom controlllers

4. Date t = wdContext.nodeZ_Hr_Ess_Pa0003_Input().nodeOutput().currentOutputElement().getE_Abrdt(); to get the E_Abrdt();

But it got null without any values. Could sum1 shed a light on this please? Thanks.

I got the following code added

		Z_Hr_Ess_Banking_Pa0003_Input model= new Z_Hr_Ess_Banking_Pa0003_Input();
		wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().bind(model);
		
		if(wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().nodeOutput().currentOutputElement().getE_Abrdt() != null)
		{
		  Date t = wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().nodeOutput().currentOutputElement().getE_Abrdt(); 
		}

and received the error

java.lang.NullPointerException

Sorry I am not good at JAVA.

Hi,

Insert the following statement after the bind statement:

Z_Hr_Ess_Banking_Pa0003_Input model= new Z_Hr_Ess_Banking_Pa0003_Input();
wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().bind(model);

wdContext().currentZ_Hr_Ess_Banking_Pa0003_Input().modelObject().execute();

if(wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().nodeOutput().currentOutputElement().getE_Abrdt() != null)
{
   Date t = wdContext.nodeZ_Hr_Ess_Banking_Pa0003_Input().nodeOutput().currentOutputElement().getE_Abrdt(); 
}

Also find out if the RFC expects any input parameters from the WDJ program. If yes, set the parameters using:

wdContext().currentZ_Hr_Ess_Banking_Pa0003_Input().set<attributeName>();

Yes It works fine now. Thank you very much.

There is one input parameter in this custom RFC. But there is another implementation problem poped up.

For this ess banking application, generally there are two projects involved. One is ess_aubank_sapcom, the other is ess_persap_{com. We have implemented the code to validate the date period in ess}per_sapcom/CvPersInfoDetailFooter, However we require the input parameter from another project which is ess_aubank_sapcom/VcPerBankAuDetail. How am I supposed to pass this input parameter from one project to another? Is there an easy way to do? Thanks.

To be more specific, it is user id i need as input parameter

Hi,

try using this line:

if(wdContext.currentOutputElement().getE_Abrdt() != null)
{
  Date t = wdContext.currentOutputElement().getE_Abrdt(); 
}

This will avoid any errors if the output element is null

Before that, execute the RFC in ECC using transaction SE37 by providing the parameters if required?

hello

1) Open SE37 execute FM check whether you are getting Date value or not. If you are getting there means there is some issue with WDJ Code.

2) Take Instance of the node . Pass required input parameters to FM and execute FM.

Check above points.

I ran SM37 and put the function module in either ABAP program name or job name. It didn't bring up any things but said no job matches the selection criteria. I am sure I typed the correct FM.
