Proxy error in Webdynpro

[Former Member]

Hi all,

I am having 2 tables in my view.In the first table total 29 records are there and in 2nd table total 4o records are there.

I selected all records in both the tables and given them as input to the function module.

On click of execute i am calling the function module execute method.

I am getting the following error as given below

Proxy Error

The proxy server received an invalid response from an upstream server.

Reason: Error reading from remote server

Can anyone plz help me out in resolving this issue

Hi,

Instead of sending all records, try to execute with one record and see it works

If it works could you pl post the code that is been used to iterate and update.

Hi,

It is working if i select all records from table 1 and upto 20 records of table 2.

But my table 2 is having total 40 records.If i select 40 i.e more than 20 it is giving the proxy error as "Error reading from Remote server"

The code i used is

List OpNumNode=null;																		//To hold OperationsNumber
	OpNumNode= new ArrayList();
	
	List OpDescNode=null;																		//To hold OperationsDescription
	OpDescNode= new ArrayList();
	int nSelOperations=0;
	int nOperations=wdContext.node_Operations_Copy().size();
	
for(int i=0;i<nOperations;i++)
	 {
			if(wdContext.node_Operations_Copy().get_Operations_CopyElementAt(i).currentChkBoxOperationsElement().getOperationsChkVal()==true)
			{
				OpNumNode.add(wdContext.node_Operations_Copy().get_Operations_CopyElementAt(i).getVornr()) ;
				OpDescNode.add(wdContext.node_Operations_Copy().get_Operations_CopyElementAt(i).getLtxa1());
				nSelOperations++;
			}
	}

int nCounters=wdContext.node_Group_Counters_Copy().size();
	for(int i=0;i<nCounters;i++)
	{
		if(wdContext.node_Group_Counters_Copy().get_Group_Counters_CopyElementAt(i).currentChkBoxCountersElement().getCountersChkVal()==true)
		{
			String  strGroupVal=null;	
			strGroupVal=wdContext.node_Group_Counters_Copy().get_Group_Counters_CopyElementAt(i).getPlnnr();
			String strAssembly=null;	
			strAssembly=wdContext.node_Group_Counters_Copy().get_Group_Counters_CopyElementAt(i).getIstru();
			String strCounterVal=null;				strCounterVal=wdContext.node_Group_Counters_Copy().get_Group_Counters_CopyElementAt(i).getPlnal();
			
}
}

//Calling the function module with parameters
			wdThis.wdGetlistCustomContollerController().execute_Copy_Operation(strMainGroup,strMainCounter,OpNumNode,OpDescNode,nSelOperations,strGroupVal,strAssembly,strCounterVal,chk1,chk2);
		


the code of function module execute is

try
	{
		Z_Operation_Input Copy Operation1 =null;
				  CopyOperation1=new Z_Operation_Input();
				  wdContext.nodeZ_Operation_Input().bind(CopyOperation1);

wdContext.currentZ_Operation_InputElement().modelObject().setPlnnr(strGroup);
	wdContext.currentZ_Operation_InputElement().modelObject().setPlnal(strCounter);
	wdContext.currentZ_Operation_InputElement().modelObject().setCheck1(Check1);
	wdContext.currentZ_Operation_InputElement().modelObject().setCheck2(Check2);
	
 Zgroup_Counter zz = null;
	 zz=new Zgroup_Counter();
	 zz.setPlnnr(GroupList);
	 zz.setIstru(AssemblyList);
	 zz.setPlnal(CounterList);
	 wdContext.currentZ_Operation_InputElement().modelObject().add_Group_Counters(zz);

for(int i=0;i<OpCount;i++)
	{

		Zoperation tt= new Zoperation();
		tt.setVornr((String)OpNumList.get(i));

tt.setLtxa1((String)OpDesc.get(i));
		wdContext.currentZ_Operation_InputElement().modelObject().add_Operations(tt);
}

wdContext.currentZ_Operation_InputElement().modelObject().execute();

wdContext.nodeOutput_Copy_Operation().invalidate();
}
	catch(Exception e)
	{
		wdComponentAPI.getMessageManager().reportException("listCustomContoller - execute_Copy_Operation - Exception -"+e,false);
	}

Padma,

For me it sounds more like problem with your ABAP code. When you get error, goto backend ECC and look at transaction code ST22 for ABAP runtime errors. If possible(I know, it is not easy to enter 40 rows of data), try to run same RFC from SE37 with same input.

HI,

At backend it is working fine...but the problem is my portal time out is 5 mins.

i keep track of the time taking to execute 20 records of table 2.It is taking around 2 mins.

If it is 2 mins for 20 records then it may be around or more than 4 mins for 40 records.

Like that the time may increase if the number of records increase..

Thats why it is givng portal time out..

Could you please suggest any other alternative to resolve this issue
