Problems with Parameter Mapping

Hi All,
I have problems with parameter-mapping. For me its a black box, sometimes it works sometimes not.
Lots of times my mappings doesnt work, and I dont know the reason.
For example: I want to map my Execution-CO to the Display-CO. For that I map the in the affected Action.
But it doesnt work, although I do have the same Context Structures, because its the same CO. The technical Name is also the same.
What could it be?
Thanks for answering me
Bye Steve

Hi Andre,
sorry for my late answer, but I'm writing my diploma thesis and wasnt at work since wednesday and so I dont have a access to our GP-System.
Hope I understood you right.
The Use Case of parameter mapping is that Users of further steps has the possibility to see the Input of previous steps.
When I dont map the parameter inside one action, it isnt possible. I tried it out with the SAP example "Time-off-process". I took the CO "Create Request" and add it in one Action (as Display & Execution). When I understand you right mapping inside an action is not necessary, to see the Inputs from further Actions --> But this way I cannot see the Inputs.
The mapping of my application works before I changed it.
I know never touch a running system, but It was necessary, we need a new Input and Output Parameter.
Cause I have 20 parameter the mapping was very time-consuming, to map every single parameter. I read a method to reduce the time: Adding a structure requires only mapping of the two structures. But now the Mapping doesnt work.
Hope you can help me
Bye Steve

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.

URGENT:Problem in a mapping with 8 tables in JOIN and using the DEDUP op.

I have an urgent problem with a mapping: I must load data from 8 source tables (joined togheter) in a target table.
Some data from 1 of the 8 tables have to be deduplicated, so I created a sort of staging table where I inserted the "cleaned" data, I mean, the deduplicated ones.
I made it to make all the process faster.
Then, I joined the 8 tabled, writing the join conditions in the operator properties, and connected the outputs into the fields of the target table.
But..it does not work because this kind of mapping create a cartesian product.
Then, I tried again with another mapping builted up in this way: after the joiner operator, I used the Match-Merge Operator and I load all data into a staging table exactly alike the target one, except for the PK (because it is a sequence). Then, I load the data from this staging table into the target one, and, of course, I connect to the target table also the sequence (the primary key). The first loading works fine (and load all the data as I expected).
For the next loadings,I scheduled a pre-mapping process that truncate the staging table and re-load the new data.
But..it does not work. I mean, It doesn't update the data previously loaded (or inser the new ones), but only insert the data, not considering the PK.
So, my questions are as follow:
1) Why loading the data directly from the joiner operator into the fact table doesn't work? Why does it generate a cartesian product??
2) The "escamotage" to use the Match-Merge operator is correct? I have to admit that I didn't understand very well the behaviour of this operator...
3) And, most of all, HOW CAN I LOAD MY DATA? I cannot find a way out....

First of all, thanks for the answer!
Yes, I inserted the proper join condition and in fact I saw that when WB generates the script it considers my join but, instead of using the fields in a single select statement, it builts up many sub-selects. Furthermore, it seems as it doesn't evaluate properly the fields coming from the source tables where I inserted the deduplicated data...I mean, the problems seems not to be the join condition, but the data not correctly deduplicated..

IPhone 3GS - "LOCATION PINNING" PROBLEM ON THE MAP

Hi everyone. I'm currently using an iPhone 3GS running on IOS4 and unfortunately facing "location pinning problem" on the map. Even though, "location services" feature is on and also "active" for photos, I quite often need to reboot my device right after I took a picture(s) in order to see the "location pin(s)" on the map.
But sometimes I don't need to do so, because it somehow captures the place the picture's taken and puts a pin on the map right away.
Do you have any ideas about where that problem might be stemming from? Appreciate your help on this issue. Thx a lot in advance...

so did you happen to resolve that "pinpointing" issue?

Why I can't open google maps on Safari? Everything have been working normally with my computer. But this problem with google maps I can't fix

Do you have an example? I develop Google maps for Web pages and haven't had problem with Safari and its extensions, only FF which I took out all the addons and plug-ins, but it wouldn't surprise if the Google map code doesn't display the map or information for the map or doesn't work with newer versions of Safari.

Help me please : Serious problems with collection-mapping, list-mapping and map-mappi

Hi everybody;
I have serious problems with list-mapping, collection-mapping and map-mapping.
Acording to specifications and requirements in a system I am working on it is needed to
get a "list" of values or an indivudual value.I am working with ORACLE 9i Database,
ORACLE 9i AS and ORACLE 9i JDEVELOPER.
I tried to map a master-detail relationship in an entity-bean, using list-mapping.
And this was very useful in order to get a "list" of details, ...but, when I wanted
to get a single value I have some problems with persistence, something about "saving a state"
despite I just want to get the value of a single detail.
I decided to change it to map-mapping and the problem related with a single detail
worked successfully, but I can get access to the whole bunch of details.
May anyone of you help me with that?
I am very confused I do not know what to do.
Have any of you a solution for that problem?
Thank you very much.

Hi,
When you switch on your device for the first time, the access points may be configured automatically based on the service provider information in your SIM card. Otherwise contact your operator or service provider to receive the access point settings if you cannot find it..

It's strange that if I use Message Mapping Test it works fine. But in pipeline not.
Do you have any idea where could be the problem?
Thank you in advance!
Best regard,
Zbynek

Hi,
To know the correct error Take the Inbound Payload from MONI and Test it in Mapping Test TAB. then u will come to know the exact error.
Procedure to take the Payload
goto MONI-Double click on MessageInbound Message ( CENTRAL ) --Payloads ---Double click on MainDocument ( application/xml ) -Just Right Click on the second window-View Source
then now Copy this and paste it in Mapping Test and Execute.

Structured mapping

Hi
Is there anything like structure mapping in xi ?? or otherwise whatever the mappings that we use like ABAP, XSLT, JAVA etc .......will be called as structure mapping ?? If I got to choose out of these which XI supports
a. Structure Mapping
b. Node mapping
c. Value Mapping
d. Functional Mapping
then I believe value mapping is the only one that XI supports. plz correct me if I am wrong.
thanks
kumar

Kumar,
As far as my references and understanding the answer to your question is
Structure Mapping & Value Mapping.
SAP Definition:
Define Mapping rules to assign fields that are semantically identical - Structure Mapping
Conversion rules to transfer the field content to target format -Value Mapping.
Best regards,

On a mac, I have lost the Scaler on Google map. I think that it is Firefox problem because the map scaler is present with Safari. Thank You

On a mac, I have lost the map scaler on Google map. I think that it is Firefox problem because the map scaler is present with Safari, so it seems that it is not a Google map problem. Thank You

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

I can find the original creation script if it is necessary.
My guess was that I need to define the foreign keys myself into the
generated schema.xml This is stated in the manual. However, this did not
help, although it changed the stack trace a little (it complains about
different classes than before):

I don't think I fully understand the error message, what exactly is wrong
here? How can I fix it?
Here's a sample of the changes I made to schema.xml:
- added the name - attribute to schema (it was missing)
<schema name="kirjakauppa">
- added the foreign key elements according to the table creation statements
given above
<fk name="Kustantaja_id" to-table="Kustantaja" column="Kustantaja_id"/>
etc...

It seems the last three options are being ignored - I still get a

file with schema names in front of tables (e.g. kirjakauppa.Asiakas, not
Asiakas),That, unfortunately, is impossible to turn off. The -useSchemaName
option controls whether the schema name is included as part of the
generated class name; it doesn't affect the mapping data that is
generated. What problems does including the schema name in the mapping
data cause?

This exception goes away if I edit the schema name out of the mapping
file from all classes.
separate classes are being generated for join tables with
primary keysDo these join tables have an extra primary key column? TheYes, they do. Ok, now I know where the problem is.
-primaryKeyOnJoin flag tells Kodo to ignore a join table with a primary
key on the join columns. But Kodo can't handle join tables with extra
column(s) just for a primary key identifier. This isn't a limitation of
the reverse mapping tool, it's a limitation of Kodo. Kodo wouldn't know
what to insert in those extra primary key column(s) when adding membersWhy not? If it can handle single numeric pk columns when making the
generated classes use data store identity, it has to generate something to
those columns. I can't see why this is different.
That is simply out of curiosity - the next thing fixed my problem:
to the join table. Of course, if the primary key is an auto-increment or
something where Kodo can ignore it for inserts, you can just remove the
<column> elements and the <pk> element from your .schema file and the
reverse mapping tool will map it as a join table appropriately.It is auto-increment, so I did this and it worked. Thanks.
, and application id is used for all classes.Are your primary keys on single, numeric columns? Kodo uses Java longsYes (int in MySQL), so that should not be a problem. They are also auto-
incremented. This seems to be the only real problem remaining with this
schema.
