LookupService.getChannel
Hi Group,
In Message Mapping UDF we are using lookup service with hard coding Business system and CC in the arguements.
Channel channel = LookupService.getChannel("Alert_Dev_BS","Alert_Call_Receiver_CC" );
it is working fine in development environment.
when we transport this to quality environment getting java exception because of hard coding development business system and cc.Business system Alert_Dev_BS targeted to Alert_QA_BS in quality,we created communication channel Alert_Call_Receiver_CC under business system Alert_QA_BS still its not working.
Both Quality and Dev SLD's are in sync each other,even we tried assigning development Business system (and created cc with same name) in quality enviornment,but still its not working.
Any sugeestions.
P.Swe are using CTS transport mechanism
Hi,
B'cos ur Business System is hardcoded in mapping, Alert_Dev_BS is not converted into Alert_QA_BS using target groups.Target Grps will only work for Business Systems.
Get the landscape dynamically and construct your Business system name. [Alert_<Landscape>_BS]. Below are 2 options:
1) <Landscape> can be a Value mapping parameter depfined as Dev, QA, Prd.
2) <Landscape> can be baed on ur SID or Exchange profile params

Soap LookupService with Decentralized Adapter Engine
Hi Experts,
I would like to use a Decentralized adapter engine with the Lookup Service on PI 7.1 , but when try to use that, it doesn't work, because Lookup Service is default configure to use Central adapter only. I would like how to set a decentralize adapter.
How to do a Soap Lookup using a Decentral adapter?
Now, I use the following:
Channel channel = LookupService.getChannel("BC_SF_***","CC**");
SystemAccessor accessor = null;
accessor = LookupService.getSystemAccessor(channel);
Thanks in advance.
Fernando Pena.You define in the communication channel, which adapter engine should be used, not in the mapping.

Hi,
I'm using a RFC Lookup in a Java Mapping. In PI 7.0 it was working fine. Now we use the Mapping in our PI 7.11 Testsystem and I get following LookupException:
The channel with object ID bde7c594d5023c38913437978a558708 could not be found in the Integration Server Java Cache. Check if the channel exists in the Integration Builder Directory and execute a refresh of the Java Cache...
The Channel name and Business Service Name are correct. If I look in the Integration Builder, my Communication Channel has a different ID as the one above in the exception.
I did a complete restart, the error afterwards was all the same. How can I refresh the cache for the ID's?
Thanks in advance

As i invoked a Cache Update for the Communication Channel in Edit-CacheUpdate in Integration Builder, i got following message:
Content of object 'Communication Channel * | BS_... | CC_IN_RFC... (DirContext)' on selected cache instance does not match the content of the object in the Integration Directory; the cache instance has not been informed of the changeHi
I've refreshed all caches in the PI system and restartet it many times. Always with the same result:
The channel with object ID bde7c594d5023c38913437978a558708 could not be found in the Integration Server Java Cache. Check if the channel exists in the Integration Builder Directory and execute a refresh of the Java Cache.
I get the channel information with the Java method LookupService.getChannel() and when i print out the channel information into the trace, i got following:
CC_xy (Party: , Service: BS_xyz, Object ID: bde7c594d5023c38913437978a558708)
The exception will be thrown at LookupService.getRfcAccessor(channel).
1. The Business System is valid and works for several Integration Scenarios.
2. The Communication Channel is valid and works for several Integration Scenarios.
3. The Remote Bapi worked under PI 7.0 with the equal Java Mapping.
Any suggestion for further debuggings or traps?
Thanks

Hi,
Please help in writing a UDF for these fields in mapping, which I need for the object Iu2019m doing currently.
The fields are like this:
1) batch_no = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/5000)+1",
2) lot_id = "TRUNC((GetMaxObjid('x_txn_sap_parts')-POWER(2,28))/500)+1",
3) How to use JDBC connection factory class in the UDF.
Some logic I can provide which I know i.e. Power (2, 28) means 2 to the power of 28 (2 multiplied 28 times), Trunc means truncate, X_TXN_SAP_Parts is a database table.The Target fields are Batch_no, lot_id & Objid.Actually, objid is mapped initially to a source field i.e. Object ID and in this function it is only being used for the calculation of the batch_no.
Thanks in Advance,

Any help is appreciated.
Regards,
DarrellFauver,
Just to narrow down the problem first remove the first udf and only use the 2nd user defined function. Also in the 2nd udf you have to change this line:
try{
// 1. Determine a channel.
Channel channel = LookupService.getChannel(Sender, "R_RFC_ERP");
In the above line instead of Sender you use the business service or business system where R_RFC_ERP RFC communication channel is created in Integration Directory. So you are hardcoding it first.
Once you have done this changes do save and test it once again. If this works then you can change back to original and your first udf needs to be checked.

Hi all,
I am doing an RFC lookup to increment counter. I am facing a problem.
I followed the code written by Michael. https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a03e7b02-eea4-2910-089f-8214c6d1b439
My udf is as shown below: -
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
java.util.Map param = container.getTransformationParameters();
String MSGID = (String) param.get (StreamTransformationConstants.MESSAGE_ID);
// filling the string with our RFC-XML (with values)
String m="<?xml version="1.0" encoding="UTF-8"?><ns0:_-GLB_-ZGT_RFBIBL00_COUNTER xmlns:ns0="urn:sap-com:document:sap:rfc:functions"><IM_V_FILENAME>CA10.NCH.FCIPAY04</IM_V_FILENAME><IM_V_MSGID>"MSGID"</IM_V_MSGID><IM_V_WRNO>DEVWR0001725</IM_V_WRNO></ns0:_-GLB_-ZGT_RFBIBL00_COUNTER>";
importanttrace.addWarning("Input value is "+m);

// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload

byte[] buffer = new byte[1024];

catch(LookupException e)

ExceptionThrower.generate("INVALID INPUT DEVWR NUMBER OR ID" );
return "Nothing";
else
return (content.substring(143,155));
The problem i am facing is that, i am not able to pass the IM_V_MSGID parameter to the function module.
The other 2 parameters i can pass. that is IM_V_FILENAME and IM_V_WRNO.
i am able to extract the message ID using
java.util.Map param = container.getTransformationParameters();
String MSGID = (String) param.get (StreamTransformationConstants.MESSAGE_ID);
and displayed it in SXI_MONITOR trace also using importanttrace.addWarning("Input value is "+m);
i got the correct MSGID in the trace.But the problem is that this value is not getting passed to the FM. Cos the table is supposed to increment the counter whenever the MSGID value changes.
I tried hardcoding the MSGID value to 'abc' or '123' like values but the same thing happended. The counter will not increment. The FM is working perfectly when i run it and change the MSGID values manually.
Thanks
PratichiHi,
We have done this by creating an FM in XI ABAP stack:
FUNCTION Z_ZBXI_GET_PRE_MSG_ID.
""Local Interface:
*" IMPORTING
*" VALUE(I_CURRMSGID) TYPE CHAR40
*" EXPORTING
*" VALUE(E_PREMSGID) TYPE CHAR40
DATA: lv_currmsgid type SXMSPMAST-MSGGUID,
lv_parentmsgid LIKE SXMSPMAST-PARENTMSG,
lv_premsgid LIKE SXMSPMAST-MSGGUID.
lv_currmsgid = i_currmsgid.
select single PARENTMSG from SXMSPMAST into lv_parentmsgid where MSGGUID = lv_currmsgid.
e_premsgid = lv_parentmsgid.
ENDFUNCTION.
You need to call this FM through RFC lookup UDF in your mapping.
Let me know if it works for you.

Error in while calling a Soap Adapter using the UDF
hi,
i am trying to make a call to Soap Adapter using a UDF.
The code of the UDF is as follows :

The above code is throwing an error while end to end testing.
the scenario is such,while graphical mapping a UDF will be used, which will create an Xml payload, and send this payload to another SOAP to file scenario.
The error in the sxmb_moni is: "Error when calling an adapter by using the communication channel CC_123085_UDF_SOAP_OUT (Party: , Service: BC_123082_REMADV_D96A, Object ID: fa9c6ee15efc30c68ec34b08034d87d1) XI AF API call failed.

Sreedhar.Hi,
The scenario is like I've to get a field (OBJID) value after using a SELECT statement from the database and use the same value for calculating another field values which is BATCHNO & LOTID.
OBJID, BATCHNO and LOTID are from the same database.
Thats all I was provided as the input.
Do let me know if you need anymore information. I'll try to give as much input to the extent I know.

Issue in standard RFCLookup using SALERT_CREATE
Hello Experts,
I'm trying to call FM salert_create using standard RFCLookup but my problem is:
Though i pass all the input values, Alert is getting created only with one value.
Below are my Queue values
but the alert is getting created only with the first value "Dummy Message".
so this means that the FM is called only with the first value.
could you please help?Hi Glory
Write an UDF and pass all the input values in a single queue. Then inside the UDF write the code for RFC look up.
Use a for loop to populate the item node. I think that will work.
Sample code
java.util.Map map;
try {
String msgid;
map = container.getTransformationParameters();
msgid = (String) map.get(StreamTransformationConstants.MESSAGE_ID);
Channel channel = LookupService.getChannel("XXXCLNT100","CC_RFC_R_PI");

My requirement is need to fetch Cost Center (KOSTL) by taking Personal number(PERNR) as Input parameter.
1) Do we have to create and import the RFC into PI ?
2) Do we need to create a UDF ? If yes, Kindly provide some useful links.
Thanks in Advance,

In XI mapping, how to get number from a number_range object in SAP R/3
HI All,
I have a scenario where I need to read a Number_range object in SAP R/3 or ABAP XI and retreive the current number.
I need to use this number during the message mapping.
(I read about JCO and RFC, but am a little confused about how-to and what is the correct approach)
Just to let you know, I do not want to pass this number in the original IDOC coming from IDOC, so I need this lookup.
Scenario:
In MM, make a call to SAP.
Get the latest number from SNRO( number-range object)
Use this number in mapping.
Any help pointers, greatly appreciated.
Many thanks

Soap lookup in PI7.31 message mapping
Hi All,
I have a soap lookup created in UDF in PI message mapping
I am taking material id from the source structure and use it as input parameter for the lookup webservice
Here is the UDF code which takes material number and returns the internal id
AbstractTrace trace = container.getTrace();
String matintid = "";
try {
//instance the channel to invoke the service.
Channel channel = LookupService.getChannel("BS_Bus","CC_SearchLookup");
SystemAccessor accessor = LookupService.getSystemAccessor(channel);
// The Request message in XML. THIS IS THE LOOKUP SERVICE
String SOAPxml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><searchTM_MATERIAL>xmlns:ns0=\"MDM_MAT_Search_MDM"><query><criteria><fTX_MATERIAL><constraint><value>"
+a
+ "</value><expressionOperator>equals</expressionOperator></constraint></fTX_MATERIAL></criteria></query><reposInfo><repositoryName>REP_MATERIALS</repositoryName><serverName>mdm6765</serverName></reposInfo></searchTM_MATERIAL>";
InputStream inputStream =new ByteArrayInputStream(SOAPxml.getBytes());
XmlPayload payload = LookupService.getXmlPayload(inputStream);
Payload SOAPOutPayload = null;
//The response will be a Payload. Parse this to get the response field out.
SOAPOutPayload = accessor.call(payload);
/* Parse the SOAPPayload to get the SOAP Response back. */
InputStream inp = SOAPOutPayload.getContent();
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
/* Create DOM structure from input XML */
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(inp);
NodeList matlist = document.getElementsByTagName("tM_MATERIAL");
Element material = (Element) matlist.item(0);
NodeList recidlist = material.getElementsByTagName("recordIdentification");
Element recidnode = (Element)recidlist.item(0);
matintid = recidnode.getNodeValue();
trace.addInfo("matnid is" + matintid);
} catch (Exception e) {
trace.addWarning("Error" + e); }
trace.addInfo("Service XXX success executed");
return matintid;
This is giving a java null point error
Errorjava.lang.NullPointerException: while trying to invoke the method org.w3c.dom.Element.getElementsByTagName(java.lang.String) of a null object loaded from a local variable at slot 16
Any idea whats going on? I am able to get response for the webservice using SOAP UI

mikeHi Mike,
What I suspect is, you get a null pointer exception because the XML tag name which you are trying to retrieve, has a namespace. Could you please instead try to use:
getElementsByTagNameNS(java.lang.String namespaceURI, java.lang.String localName)
Returns a NodeList of all the Elements with a given local name and namespace URI in document order.
Let us know if it works.

Hi everyone!
First, I must say that I don't know anything about java/XML programming(I'm sorry)!
I'm just looking for some guiding lights for the following;
In the Message Mapping (IB), I'm trying to do a RFC Lookup to R/3 using a BAPI call. I followed Michal Krawczyk's "Mapping lookups - RFC API:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a03e7b02-eea4-2910-089f-8214c6d1b439
And now I need to parse the XML response and retrieve a value from it!
I would like to know if the following portion of code is ok and wheere should I put it?
Code:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
// Create DOM structure
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(content);
// Lets find my tag
NodeList list = document.getElementsByTagName("Number");
Node node = list.item(0);
if (node != null) {
node = node.getFirstChild();
if (node != null) {
tagValue = node.getNodeValue();
Thanks a lot for your help!Thank you for the links!!!
I've consulted all of them and when I try to run the code, I'm getting the following message:
unreported exception org.xml.sax.SAXException; must be caught or declared to be thrown document = builder.parse(result.getContent());
Could you help me fix that issue?
Here's the code in question
String m = "<?xml version="+"1.0" "encoding=""UTF-8""?>"
"<ns0:BAPI_CUSTOMER_FIND""xmlns:ns0=""urn:sap-com:document:sap:rfc:functions>"+"<RESULT_TAB></RESULT_TAB><SELOPT_TAB><item><COMP_CODE>1000</COMP_CODE><TABNAME>KNA1</TABNAME><FIELDNAME>SORTL</FIELDNAME><FIELDVALUE>004258</FIELDVALUE></item></SELOPT_TAB></ns0:BAPI_CUSTOMER_FIND>";
