How to map multiple occurrences of a source field into a target field

Hi friends
I need multiple occurences of MATNR field, of idocs collected, to be concatenated into a single field on target side.
Warm Regards
Arjun Ghose

Hi Priyanka
I am using the below code
String material ="";
for(int i=0; i<MATNR.length();i++)
material = material +MATNR; //var(i)
result.addVAlue(material);
But I am getting the below errors:

LSMW - ME21 How to map multiple line items

Hi all,
I am using LSMW tool with batch input recording technique to create POs via ME21. I have defined source structures as HEAD with POSI as its subordianted structure. This settings worked perfectly for one single item line. However, it created a new transaction for each line item in the file. I did some searches in this forum and I noticed that someone suggested to dynamically set the line positon at the processing points. I tried a few times and could not get it work. Anyone knows how to map multiple items in LSMW, please help.
Here is part of my recording:
EKPO-EMATN(01)                 000995NM
EKPO-MENGE(01)                                 1      RM06E-EEIND(01)                2006.04.27             EKPO-NETPR(01)                             10         EKPO-WERKS(01)                 0001                   EKPO-LGORT(01)                 0001
My input file looks like this:
H 77777400 NB2006.05.140001001T
L000995NM00000000052006.05.15         1000010001CAON
L000998NM00000000052006.05.15         1000010001CAON
H 77777400 NB2006.05.140001001T
L000995NM00000000052006.05.15         1000010001CAON
Thanks!

Hi
If you have used a b.i. recording, all abap code is inserted in std table /SAPDMC/LSGBDC.
The program to generate the B.I. session is automatically created when you run "Create Batch Input Session" step.
What means the numbers of items you can insert depend on the totals of items you have used while creating your b.i. recording:
If you have simulated to insert only one item, you'll be able to insert only one item in your project.
So you should simulate to insert severals items not only one, but I think it should be better you use a std method to create PO by LSMW:
- Std B.I: object 0085, method 0001 (RM06EEI0);
- BAPI   : object BUS2012, method CREATEFROMDATA1

Source selection derived from target field Cons Chart of Accts is empty

Dear,
When I run the LDS, The system issues this error message :
"Source selection derived from target field Cons Chart of Accts is empty"
Although, mapping of Cons Chart of Accts in LDS for this method is defined as constant value.
I can't load data from raw data cube. What can be the reason ?
Thanks,

Source selection derived from target field Cons Chart of Accts is empty
Message no. UCT8257
Diagnosis
The system derives the source selection from the selection for target field Cons Chart of Accts. The resulting source selection is empty.
System Response
The system cannot read any source data.
Procedure
Examine the mapping rule for field Cons Chart of Accts. Make sure that the inversion of the mapping rule does not produce an empty selection or lead to conflicting values.

How can I map multiple sourcelines of the same position into 1 targetline?

Hi all,
I have a mapping problem in XI. I have no idea how to do the following mapping in the IR. My inputfile contains of 1 headerline and mulitple positions, and it has got multiple lines per position (with different data in it). The targetfile has got 1 headerline and multiple positionslines in which I have to "merge" the data from mulitple source-positionlines. It looks like this:
source structure:
headerdata
position1 part1 (posnr, article number, quantity, articletype,...)
position1 part2 (posnr, article price, payment conditions,...)
position1 part3 (posnr, route,...)
position2 part1
etc
target-structure:
headerdata
position1 (posnr, articlenr, quantity, articletype,price, payment conditions, route)
position2 (same)
position3 (same)
etc
Now I have to map part1,2 and 3 of the source structure to the 1 and the same target-line. I guess I would need some kind of lookup of the positionnumber in my message-mapping. But how do I do this? Copying the targetline 3 times is not an option as the target-utility only accepts the structure as described above....
Hope anybody van help
Thanks,
William

Hi,
U can do it with UDF but it is more simpler with normal graphical mapping refer the following steps.
1) To map header node for your example (position1) refer the following steps,
posnr --> RemoveContext --> sort --> splitByValue(valueChange) --> CollapseContext --> position1
2) for posnr in target side also u can use same mapping with some change i.e.
posnr --> RemoveContext --> sort --> splitByValue(valueChange) --> CollapseContext > splitByValue(EachValue)>posnr.
3) For other node like articlenr, quantity, articletype,price, payment conditions, route refer the following mapping.
1st do this.
posnr --> RemoveContext --> sort --> splitByValue(valueChange) --> CollapseContext --> splitByValue(EachValue).
then take IfWithOutElse function give 1st input as output of CollapseContext
2nd input is value like articlenr, quantity, articletype,price, payment conditions or route(one of it) --> FormatByExample(using posnr --> RemoveContext --> sort --> splitByValue(valueChange)) node
Output of IfWithOutElse give to splitByValue(EachValue)
Then give it to Target field.

Rohit.

Mapping Multiple Source fields to Single Target Fields with differnt Values

Hello Friends,
I am having a senario where I have to mapped multiple fileds from source str. to same Idoc Fields with ( differnt default values )
E.g Source Str.
- ShopNO
- OrderTyp
Has to mapped to Idoc Str E1EDK14-Orgid.
E.g Mapping:
So when ShopNo will mapped to E1EDK14-Orgid the default value should be "MOP" & E1EDK14-Qualf should be 019
and when OrderType will be mapped to E1EDK14-Orgid the default value should be "STD" & E1EDK14-Qualf should be 012
So I tried of using node "UseOneAsMany".....but there I cant define the vaule of field orgid, and seconly how to specify the values of field Qualf?
Do i need to write my own specify function ? or I can sovle this issue using standard avaiable functions ?
Regards,

Hi Ravi,
Thanks for your reply....
I am facing following problem... when I try to duplicate the segment and do mapping....... and then when I save, I got following error msg:
The source or target structure has been changed or could not be found in the Integration Repository. The mapping definition contains elements or attributes that do not exist in the changed structure. The relevant entries will be deleted
Target structure has no such path: /ZARVO_ORD/IDOC/E1EDK05[1]/KSCHL. Skipping mapping
Target structure has no such path: /ZARVO_ORD/IDOC/E1EDK05[1]/KRATE. Skipping mapping
Any suggestion ?
in other words, when I do duplicate it creates me the segment, but when I save it, it gets disappered .........

How to map multiple output values to the output schema in biztalk mapper?

Hi,
In my biztalk mapper, I am using a "database lookup" functoid which is linked to a "Value Extractor" functoid. A source schema field is linked to the database lookup functoid which is linked to a "Value Extractor" functoid
which is linked to the destination schema field. After passing the required parameter values in the database lookup functoid (lookup value, conn string, table, column name), I know that the result set may get multiple rows which are transferred to the "value
extractor" functoid.
Now what I want is to create a record in destination schema for each row in the result set. My current mapping is as below:
1) Source record > looping functoid > destination record
2) Source record field > Database functoid > Value Extractor functoid > dest record field
but this mapping is giving me only the first value in result set.
Please help me in this so that my map creates a destination record for each value in the result set.
e.g. if query [select * from employees where surname='Brown'] returns five records, then I would like five records in the destination schema.
Thanks
manibest

Hi Muhammad Ehsan,
Thank you for the useful suggestion. however, I have only one difficulty in building your suggested solution. in my query (select
* from employees where surname='Brown'), the value of surname is coming from the source schema field which could be different in each source schema record field.
lets say that source schema instance has 3 records in it as below:
<Records>
<Record><Surname>Brown<Surname></Record>
<Record><Surname>Atkinson<Surname></Record>
<Record><Surname>White<Surname></Record>
</Records>
For each of above records the database query should run with the relevant surname value. if database has 5 records for "Brown", 3 records for "Atkinson" and 1 record for "White" then the destination schema should create (5+3+1) = 9 records in
total.
To create a destination canonical schema that works fine, I have to somehow pass this surname value from source schema as parameter so that it uses this value to poll the database and get records. Is there a way I can pass this surname value as parameter
to the destination canonical schema? Thank you so much for the help.

Mapping multiple source fields to one target field

Hi,
I'd like to take the XML content fromy my outbound message and put this into a single field within my inbound message.
Please can someone suggest a suitable XSL mapping or user defined function I could use to achieve this.
Thanks,
Alan

Hi,
OK, so I now have the XML data in one wrapper tag called inbound but when this is passed to the inbound ABAP proxy I obtain the error as listed below.
Any ideas how I overcome this?

Message mapping - Map 2 source contexts into one target context

Hi,
I have an issue as follows:
Source context 1 (defined as 1.....unbounded)
Source context 2 (defined as 1.....unbounded)
Target context 1 (defined as 1.....unbounded)
I need to map both source contexts into the single target contexts.
For example....
Source context 1 has 3 entries
Source context 2 has 2 entries
Target context would have 5 entries in total (Source context 1 and Source context 2)
I have only limited knowledge of working with multiple contexts so need a bit of advice.
Can someone provide an easy way to do this ? I'm sure there is.
Cheers
Colin.

The answer is quite simple.
Right-click on the target node in the mapping editor and select the option "duplicate subtree".
You will then have two destination nodes.
Now you can map source1 to target1 and source2 to target2

How to map the method action return value directly into screen using variables?

Hi,
My JDev version is 11.1.1.6.3.
I have a 'MethodAction' defined in PageDef file, that goes to model layer and return String value. As this needs to be executed during initializing of pageDef, I have also added an 'InvokeAction' for that.
<executables>
 <invokeAction id="invokeSayHelloId" Refresh="ifNeeded"
 Binds="sayHello"/>
 <variableIterator id="variables">
 <variable Name="Name" Type="java.lang.String"/>
 </variableIterator>
</executables>
<bindings>
 <methodAction id="sayHello" InstanceName="HrAMDataControl.dataProvider"
 DataControl="HrAMDataControl" RequiresUpdateModel="true"
 Action="invokeMethod" MethodName="sayHello"
 IsViewObjectMethod="false"
 ReturnName="data.HrAMDataControl.methodResults.sayHello_HrAMDataControl_dataProvider_sayHello_result">
 <NamedData NDName="pName" NDValue="Michael John" NDType="java.lang.String"/>
 </methodAction>
</bindings?
Requirement:
I want to map the return value of this method action directly into screen by making use of PageDef variables.
Question:
I. I need to know how to map this return value direcly as exprssion against PageDef variable.
2. If Question 1 is achievable, assuming the method action returls List instead of String (I know well it returns 2 items), can I map the 1st Item against Variable 1 and 2nd Item against Variable 2 directly?
Thanks in Advance.
Ragu

Thanks Frank, but If I directly map the MethodAction's result to UI, there are chances where it might get executed whenever I refresh the UIComponent (UIComponent to which the methodAction result is mapped. Isn't so??). Instead, If I invoke the MethodAction using InvokeAction, I can get the control on when it should get invoked (using RefreshCondition). If I assign the variable to UIComponent (Assume I've mapped the method action result to variable using expression), refreshing of UIComponent will not cause any performance issue I feel.
Correct me If I am wrong.

How to map multiple source structures to single target structure

Hi all,
I have the scenario of 2 input files so i am using BPM for it. I have created the message types of the 3 input files. I have to finally generate an XML file which will contain the data of all the 2 files. That is i have to do 3:1 mapping.
Source Structure of File 1:
DT_PWC_Customer
RECORDSET
CUSTOMER
 REF_NO
 CUSTOMER_NO
Source Structure of File 2:
DT_PWC_Customer
RECORDSET
METER
 REF_NO
 METER_NO
Target Structure of Final Output File:
DT_PWC_CustomerMeterData
RECORDSET
CUSTOMER_METER
 REF_NO
 CUSTOMER_NO
 METER_NO
Above nodes i have shown in a heirarchical order..nodes with same indentation are at same level.
Can anybody tell me how to do this mapping in IR in graphical editor.
RAJEEV GUPTA

Hi,
To elaborate my requirement, I want to tell that since i will be having 2 input files- one for Customer & one for Meter. I want to finally generate one XML file which will have data from both these 2 input files. That is, if Customer file has 3 records(3 REF_NO, 3 CUSTOMER_NO) and Meter file has 4 records(4 REF_NO, 4 METER_NO), the final output XML file will have 7 records(7 REF_NO, 3 CUSTOMER_NO,4 METER_NO).

How-to map multiple explicit search help values to context attributes?

Hi,
I have a custom explicit Search Help with multiple attributes set as export and uses search help exit for data retrieval. I have set this Search Help for one of the context attribute that is binded to one of the input fields on view.
Now, is it possible to dynamically map other export attributes from this Search Help to other Context attributes?
I know this works for Input helps that are directly derived from check tables but not sure how to do it for explicit Search Helps.
Can anyone please confirm and let me if this is possible? If yes, then can you please share an example or describe how to do it?
Thanks and Regards,

Hi Srinivas,
Check this ..Search help can be dynamically assigned to a field.
data lo_nd_info type if_wd_context_node_info.
lo_nd_info = lo_nd->get_node_info( ).
CALL METHOD lo_nd_info->set_attribute_value_help
EXPORTING
name = 'ATTR1'                  " Your attribute Name
value_help_mode = '121'    " Valid value help mode
value_help = 'Z187442'.      " Search help name
The various possible values that you can pass to value_help_mode are as shown below.
deactivated 101
automatic 111
ddic 121
ovs 131

How to map multiple drives to an AD network using Applescript?

Hi all, I'm trying to map AD accounts over to my LDAP Mac server which is pretty straight forward.
In the script I want to map their home drives so they are the same as they are in AD.
Ex (with wonderful made up names):
mount volume "smb://servername.ad.internal/user home folders/" & username
Here's the issue, the user accounts for my AD domain are in two seperate locations:
servername.ad.internal/user home folders/
servername.ad.internal/user home folders/more users/
So, the script happily mounts those folders that meet the first instance but crashes out if the meet the second instance.
How can I write a script that tries to map using the first path, and then suppresses and redirects the error to map the second path on failure of the first?
Fairly new to applescript being a linux/MS person so be gentle!
Thanks,
Will

Problem in work flow of PE while mapping 2 source structure into 1 target

We have scenario in BPM where in we have to mapp 2 source structure's into target.
To be more specific one structure occurance is 0 to unbounded and other one is of single occurance.
We have done the mapping with target structure and tested it manually in mapping . its working fine..
While testing it in Configuration scenario, In the workflow process i.e PE process flow, we were not able to get one of the source message structure as the input Message. Instead of two source messages, it is seen only one. Please guide us in this issue.

actually we are receiving only one message, henece we do not need a correleation. But once we receive this message we are splitting into multiple messages in the transformation step. and we use these split messages in different transformation steps. but in one of the transformation steps we are unable see one of the split messages in the transformation step(though we have used the proper container element.). Please let me know if any ideas on this.

How to configure GG to merge two source tables into one destination table?

I have two tables at source (say S1 & S2), I want to merge these tables and replicate to a single target table (Say T1).
Does GG support this type of replication? If so, could any one let me know how to configure Table and Map parameters?
Thanks in advance.

It is possible. In the extract capture both the tables.
Extract parameter
table s1;
table s2;
Replicat parameter
map s1, target t1, keycols (...);
map s2, target t1, keycols (...)

JDev 11.1.1.2 - How to map fixed xml tags in "any" element of the target?

<xs:sequence minOccurs="0" maxOccurs="unbounded">
<xs:any/>
</xs:sequence>
</xs:complexType>
</xs:element>
I want to map as below in JDev xslt. The 2 new elements are fixed and do not change. I tried to use copy-of but did not know how to do this? Any sample would help.

I would think if you intanciate the XMLReference and use IIDXMLElement GetChildCount / GetNthChild would do what you are looking for.
