Reset counter in message mapping

Hi,
I'm creating several UNH segments from one IDOC and need to reset a counter, used in a subsegment, for each UNH.
I am using the standard *counter function. Is it possible to reset that counter or do I have to create an own counter? In that case can anyone please help me with that?
Thank you!

HI,
there is a global variable concept in XI which u can use for your Sequence Number concept. And can be reset with the use of UDFs. I doubt if you can reset the Counter API
If you are on SP14 and above, just take a lookat this blog and the GLOBAL Variables Section

Record counter in message mapping

Hi all,
I'm having a multiple IDOCs to 1 file scenario, and structure is like this:
source:
IDOC(1..unbounded)
target:
structure1(1..unbounded)
>field1(1..1)
IDOC is mapped directly to structure1.
for field, I need the number of total IDOC structure sent.
This means, if 3 IDOC are coming, then field1 need to have value "3".
I used the "count" function from the statistic functions, but when I got multiple IDOCs, I'm having a mapping error.
How can I count number of incoming IDOCs in a field inside each structure per IDOC?

Hi Chapa,
After "count" use "CopyValue" (index 0), it will work. FYI [Link1|http://help.sap.com/saphelp_nw04/helpdata/en/26/d22366565be0449d7b3cc26b1bab10/frameset.htm]

Count-Function in Message Mapping

Hey, trying to map following structures:
message
-m1
--m11
-m2
--m22
-m3
--m33
to
message
-m1
--m11
-m2
--m22
-m3
--m33
-f1
--countItems
The nodes m1,m2 and m3 can appear 1..unbounded. In target structure I would
like to have the numbers of all nodes (m1,m2,m3).
For example: In this source structure m1,m2,m3 appear only one time. In the
field countItems I would like to have the number 3.
I tried the count function, but it could only count the structure where I used it (in
this case: f1).
How can I count the above-mentioned nodes?
thanks
chris

Hey,
thanks for your answers.
But I still couldn't understand how to do this. I open the message mapping for field f1, but the count function could only be set on an target-element, so where to set the counters for m1,m2,m3? Do I have to insert extra fields under m1..m3?
If I do the counter would increment with every node, so if I have two times m1, in second tree of m1 a two will be insert. If I use the add function, only for these two tree the result would be three!
@Gangisetty Vijaya Bhaskarudu
Is this just one UDF? From where he knows, which nodes he have to count, if I have more than m1..m3, but only want to count this three?
@ sasitharan
same problem as mentioned above:
this doesn't work:
m1--count---\
I can't use m1 as input for count! Or do I have a wrong count function?
<b>....au damm, answered my own question. Of course. I use COUNTER and you use
COUNT!!!!!!!!!!!! I will try this with COUNT!!</b>
thanks

How to reset junk mailbox message count?

Apologies if this is resolved elsewhere, but I can't find it. For the past several months I have received several "ghost" spams per day. (There is nothing in the sender, message header, or body.) The mail filter does not catch them. I wrote a rule (based on a suggestion in this forum) where if "from" does not contain "@" it is sent to junk. It seems to work fine. Since about then - and I'm not sure if the events are simultaneous - my junk mailbox won't reset its count of messages. I have erased all messages in it and SOME are erased, with the count being reduced by 3-4. The total shown next to the mailbox icon continues to grow, however. It is now around 50. There appear to be no messages in the mailbox. This began before I upgraded to Tiger and has continued since then. Mail seems to work fine, but it is very irritating. Thanks for your help.

Hello Michael.
Assuming this junk mailbox is for a POP type account, quit Mail first and using the Finder go to Home > Library > Mail > this account named folder (named by the user name and incoming mail server for the account) > Junk.mbox.
Delete the Junk.mbox folder and empty the Trash.
When re-launching Mail, a new Junk.mbox will be created automatically by Mail within the account named folder when receiving the next message that is automatically or manually marked as junk.

Message Mapping - Initialize counter every context change

Hi all,
is there any way to develop a counter customer function in a graphical message mapping so every context change of a field the counter initializes?
Imagine i have the following structure:
1 DATA
1.1 DETAIL
1.2 DETAIL
2 DATA
2.1 DETAIL
2.2 DETAIL
and i wanna count DETAIL fields but initialize the counter every DATA field. Is there any way to do it?
Thanks a lot.

Hi,
If your Source structure is
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_DATA xmlns:ns0="http://yash.com.YH1309">
   <DATA>
      <DETAIL/>

   </DATA>
   <DATA>
      <DETAIL/>
      <DETAIL/>
      <DETAIL/>
   </DATA>
</ns0:MT_DATA>
and You want the Target as

Problem in message mapping index.

HI All,
I am doing idoc to file scenario.
I have a problem in message mapping.
Issue is,
pallet1
palletheader(here i used counter to increment the value)
palletline(here i used INDEX to increment the value)
        pallet linenumber1(it should be 1)
        pallet linenumber2(it should be 2)
so on       )
so on
pallet2
palletheader
palletline
        pallet linenumber1(here again it should be 1)
        pallet linenumber2(here again it should be 2)
so on              )
so on
In INDEX we have option called reset index in that we have two radio buttons
one is "reset index to intial value with each new context"
and next one is "donot reset index to intiak value"
if i use the first radio button which is working fine in only one pallet and more pallet lines but not more than one pallet.
If i use the second radio buttton which is working fine in more than one pallet but not satisfying the more pallet lines in one pallet.
Can you please help me on the issue

my requirement is like this.
IF DELVRY05/IDOC/E1EDL20/E1EDL24/POSNR equals to /DELVRY05/IDOC/E1EDL20/E1EDL37/E1EDL44/EXIDV
then map to 'pallet line' .
I tried to keep posnr context as E1EDL20 and also IDOC level.
And at the same way to EXIDV too.
pallet(1 to unbounded)
   pallet header(1 to 1)
   pallet lines(1 to 1)
        in sub level pallet line(1 to unbounded) (here i applied the index logic)
The out put should be pallet line 1,2,3,----- so on
In the second pallet the pallet lines should be again 1,2,3,4-------so on .
But when i try to apply thsi logic,
I am getting only one pallet line instead of two.
second is not comming .
please help on this i am facing this problem for the long time back.
if i solve then i can complete my scenario.

Message Mapping fails because of RFC

Guys,
1) I have some messages failed in SXMB_MONI because message mapping for those interfaces was not executed successfully. In trace I can see the following:
"com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=A ASHOST=121.12.2.15 SYSNR=02 GWHOST=121.12.2.15 GWSERV=sapgw02 PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner not reached (host ?, service ?) TIME Wed Jul 11 07:20:27 2007 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 COUNTER 1024</Trace>"
I realize it is a network connection problem, but..
Any ideas?
2) Actually, in my mapping programs I have to perform many RFC's to both XI and target/source SAP systems, in order to get some information. The techique that I am using for RFC's is through Java's com.sap.mw.jco.* package. And I connect to systems by giving the IP address, system number, username and password of the systems and then I execute the remote enabled function modules.
However. when I have many RFC's some of them fail, maybe because the maximum number is reached. And then I have to manually restart them from SXMB_MONI and they are successfully processed.
Any ideas?

But you said you call many RFCs inside XI, right?
The proper way of doing it is not using JCo directly, but using Mapping Lookup API instead. In this way, you won't need to maintain the connection details inside the code, but in the communication channels.
Check this out: https://help.sap.com/javadocs/NW04S/current/pi/index.html (lookup api).
There are some code examples within the classes (for example, RfcAcessor).
I think there is also a SDN documentation by Michal Krawczyk regarding RFC Lookups.
Just search for it.

Henrique.

Severe Problem With Message Mapping

Hi,
I have got a message mapping which results in the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<ns14:expost_generation xmlns:ns14="http://mywebsite.xsd">
<timeStamp>2006-03-15T15:27:16</timeStamp>
<source name="xyz">
    <generation date="abc" value="def" />
    <generation date="abc" value="def" />
    <generation date="abc" value="def" />
</source>
</ns14:expost_generation>
My problem is that I have to suppres the ns14 prefix. The opening tag should be: <expost_generation xmlns="http://mywebsite.xsd">
The closing tag: </expost_generation>
Does anybody know how to achieve this?
Kind regards,
Heiko

Hi Heiko,
on the level of the expost_generation-Tag the two definitions you gave are logically equivalent. Hence, no software consuming the XMLs should prefer one style.
However, when we look at the subelements there is a great difference.
In the xml you posted first all subelements (timeStamp, source,...) lie in no namespace.
On the other hand when you declare the tag expost_generation as you described afterwards (with a default namespace declaration) and then proceed as in the first example, then all the subelements will lie in this namespace, too (unless you again reset the default namespace in all these elements).
I assume that the Schema you use in the Message Mapping describes a document with only the root being namespace qualified but the service consuming the document expects a document with all tags being namespace qualified.
Greetings
Stephan

Help with Message Mapping - Context Change

I need help with the following message mapping. I am filtering by EMP_STAT in the Message Mapping. I have this working for the ROW structures, but I can get the HEADER/REC_COUNT field to calculate. I can do just a record count of ROW and get it to work, but I can't get it to work with the filter EMP_STAT = 'REG' added. I get a context error. Could someone send me the mapping code.
Sender XML----
<RECORD>
<ROW>
<EMPLOYEE>111</EMPLOYEE>
<EMP_STAT>REG</EMP_STAT>
</ROW>
<ROW>
<EMPLOYEE>222</EMPLOYEE>
<EMP_STAT>PT</EMP_STAT>
</ROW>
<ROW>
<EMPLOYEE>333</EMPLOYEE>
<EMP_STAT>REG</EMP_STAT>
</ROW>
</RECORD>
Receiver XML----
<RECORD>
<HEADER>
<REC_COUNT>2</REC_COUNT>
</HEADER>
<ROW>
<EMPLOYEE>111</EMPLOYEE>
<EMP_STAT>REG</EMP_STAT>
</ROW>
<ROW>
<EMPLOYEE>333</EMPLOYEE>
<EMP_STAT>REG</EMP_STAT>
</ROW>
</RECORD>

Hello,
You can use this mapping
For REC_COUNT:
EMP_STAT -> equalsS: constant:REG -> ifWithoutElse -> removeContext -> count -> REC_COUNT
                                 EMPLOYEE -> /
For ROW:
EMP_STAT -> equalsS: constant:REG -> ifWithoutElse -> removeContext -> ROW
                                 EMPLOYEE -> /
For EMPLOYEE:
EMP_STAT -> equalsS: constant:REG -> ifWithoutElse -> removeContext -> SplitByValue -> EMPLOYEE
                                 EMPLOYEE -> /
For EMP_STAT:
Constant: REG -> EMP_STAT
Hope this helps,
Mark

Message mapping Query

Hi,
I have (xml)file to idoc scenario where the xml xsd has following structure.Its is PO posting
batch
header
item
now in batch i have a feild total po which i need to validate with the total number of po in the file and if the two are not matching then i need to send a error xml file back to same ftp server (insted of sending it to R3 for idoc posting), so my receiver will change based on this check.
Can anyone let me know how to do this.

Yes ,
Certainly , You can do this without BPM.
There may be few other ways also , i am explaining you one out of them .
Message Mapping . Create three message Mapping .
i. ) File sender to IDOC Receiver
ii.) file sender to file receiver (with error information).
iii.)file sender to receivers ( Message type :Receivers namespace : http://sap.com/xi/XI/System) : This one will be used to choose receiver dynamicaly.
at target Message type :Receivers the element Service Populate with the value of buisness system based on your condition.
like in your case : IDoc receiver Buisness system if counts matches, else File Receiver buisness system if count doesnt matches.
Operation Mapping . Create three Operation Mapping .
i. ) File sender OUTB to IDOC Receiver INB
ii.) file sender OUTB to file receiver (with error information) INB.
iii.)file sender OUTB to ReceiverDetermination INB
( target service interface :ReceiverDetermination namespace : http://sap.com/xi/XI/System) : This one will be used to choose receiver dynamicaly.
Rest is same in ESR Side.
Now let us come to Key points in ID.
1. Receiver Determination.
It would be extended : Here choose third Type Operation mapping : iii.)file sender OUTB to ReceiverDetermination INB
this will deside, Receiver Dynamically.
2. Interface Determination.
now for each buisness system , create interface determination and choose appropriate operation mapping.
Rest steps would be same ....
Do ask if found any problem .

Sequnce Number generation in Message Mapping..

Hello All,
I am using this thread as a reference for declaring a Counter for unique sequence number generation...
Sequence Number in XI Mapping
-> define a global variable by clicking the JAVA_SECTION_TOOLTIP icon on the design tab of source message type of ur message mapping.
enter the following in the GlobalVariables Section
Integer counter =0;
-> define a user defined function (SeqGen let's say)
write the following code in it.
Integer seq = 0;
GlobalContainer globalContainer = container.getGlobalContainer();
a = globalContainer.getParameter("counter");
seq = globalContainer.getParameter("counter");
seq = seq + 1;
globalContainer.setParameter("counter",seq);
return a;
now use this user defined function (SeqGen)in all ur mappings to the sequence no of ur line items.
If u could just elaborate on creation of UDF.. on what are we goin to pass in the variable 'a'... while creating the UDF. ??
Harpreet..!!

Hi harpeet,
A UDF can be of two types a Simple UDF and Adavnced UDF.
This is a case of a simple UDF,
A simple UDF returns only 1 element as an output.
here 'a' is such an generated output. you can assign this to any numeric filed of ur target stucture
This UDf does not require any input Field from the message.
These functions are known as generating functions.
Hope this explains.
Reward points if useful.

Abhishek

Count fields in Mapping

Hi all,
We are using PI7.0, we have a requirement where we need to count the number of fields occurring in the target and that count has to be given in one of the field. The target elements vary according to the input. To be clear, for example
If 5 fields are formed in the target, the 5th field should have the number 5 as the output.
Can this be achieved in message mapping ?
If so, kindly help me .
Regards,
Sherin Jose

How will that work ? Help me how i can achieve by using that.
Index function is used to find the position in a string right. Correct me if i am wrong.
My requirement is,
I have 10 fields in source and 10 fields in target. Based on the input the number of fields formed at the target may vary. What i exactly need is that when 8 fields are formed in the target in that structure, a field in that structure should have the number of fields that were formed in the target.
Source                   Target                 values
FirstName               Name                  Raghu
EmpNo                    ID                        005
Salary                    pay                      12000
Fields                     Field                     4
As highlighted, the fourth field should say the number of occurrences of the target fields. I need to know how i can get the last field dynamically when the target is formed.
Regards,
Sherin Jose

Sudeep,
Let we try this way. I'm sure you might have some existing mapping objects in IR.
Try to change that object(Description give some name) and activate again the object.
Reply your results whether you are getting the same error.
One sec before changing the object just test the mapping and change the object.
Best regards,
