How to clear JCA interface parameters in RFC call?

hi all,
this is my trouble:
I have to call an RFC Function with JCA connector in an EP6 SP2. The connection it's ok and works well. But if i modify the interface parameters of the RFC function i must to reboot the portal for read the new interface.
It's possible to read the new interface without restart the system.
Thanks for all your helps!

How to reprocess an interface with a RFC problem

Hi.
I have a simple scenario File->RFC->FILE
In the BPM that i use, i send some data vía RFC to a R3 Backend and retrieve it. FInally, i create a file with the result.
The send step that sends the data to R3 backend has been defined with a transport confirmation.
My problem is that the BPM has send the info to R3, has received the ACK and at this time, the R3 has crashed.
Now R3 is back again and the Receive Step of the BPM is waiting for the answer. I've checked Sm58 in R3 Backend but no entries in it.
How can i send once more the RFC now that R3 is ready?
Thanks.
Inigo.

If so it is like of 2 scenarios. You need to have 2 receiver determinations
1) Sender File to RFC in R/3
2) R/3 to File
But if you want to execute these 2 separate scenarios in sequence then the current design should have these BPM steps
1) Receive File data
2) Transofrmation step ( InputFile to RFC1)
3) Send the RFC data
4) Receive the RFC2 data
5) Transformation Step (RFC2 to OutputFile)
6) Send this to file
You can avoid transformation steps inside the BPM. for this you need to do mapping outside the BPM

Yes. Really.
They likely did not miss it. They either have much more important priorities or simply chose not to provide it.

How to access Dynamic Region parameters from a called taskflow?

HI,
i have i dynamic region embedded into a page.
The region points to a bounded task flow. I want to pass parameters to the taskflow and doing that by specifying region params.
<taskFlow id="dynamicRegion1" taskFlowId="${test.dynamicTaskFlowId}"
xmlns="http://xmlns.oracle.com/adf/controller/binding">
<parameters>
<parameter id="inputParameter0" value="#{backing.comp1.value}"
xmlns="http://xmlns.oracle.com/adfm/uimodel"/>

But for me is not clear, how can i acces them from a taskflow that i called (to which points region)

How to set the language for a RFC call ?

Hi,
when calling from BSP (WAS620) to our R3 using RFC the results (units, ...) are always in DE. How do the call to get the results in EN?
Language in RFC Destination/Logon&Security does not have an effect.
thx for your support.

Martin,
I am not sure whether this is a logon problem.
If you run the function module in transaction SE37 then you will get PC because there are some exits associated to it.
When you call it from "outside", then the internal value is returned to the caller.
The same happens when using BAPI from languages like Java or .Net
The material field - in particular - is well-known for this behaviour.
Hope someone else could testify because I haven't crossed the problem myself.
Check this thread for instance:
sap.net connector error
If you have a doubt, then set an external breakpoint in the remote system for the RFC user. Then, check the content of the sy-langu field.
Best regards,
Guillaume

Problem passing an export parameters in rfc call using the function control

Hello,
I use SAP Remoute Function Control (wdtfuncs.ocx) in my C++ application. I can execute remote functions, if they don´t need any export parameters:
CSAPFunctions m_Functions;
CFunction f;
f.m_lpDispatch = m_Functions.Add("RFC_CREATE_DOCUMENT_MASTER");
f.Call();
How can I set the export parameters?
Any help appreciated.

Adaptive RFC Calls

Hi everybody,
From the tutorial I know how to populate a table from an RFC call by using 'create binding' from the context menu of the table. I want to know how I can output data from a RFC without having an input field and search button. So as soon as I launch the Dynpro app there is some data in the table from the backend.
Thanks.
MK

You would put your call to the BAPI in the wdDoInit method of the controller.
Here is some code from an application I did where there is no input parameter and the data is displayed in the application right away.
public void wdDoInit()
    //@@begin wdDoInit()
//       Bind to the context
          Z_Ep_Get_Ytd_Sales_Input input = new Z_Ep_Get_Ytd_Sales_Input();
          wdContext.nodeZ_EP_GET_YTD_SALES().bind(input);
          try {
//      calls remote function module Z_EP_GET_YTD_SALES
               wdContext
                    .currentZ_EP_GET_YTD_SALESElement()
                    .modelObject()
                    .execute();
          } catch (Exception ex) {
//       If an exception is thrown, then the stack trace will be printed
               ex.printStackTrace();
          wdContext.nodeOutput().invalidate();
    //@@end

How to clear parameters defined in selection screen on back button

Hi,
I have a report with parameters, few being input fields, and check boxes. After report is executed when user selects the back button, the selection screen is displayed again but with the old selection values. I want to clear them.
So in the Initialization even I added the code to clear all these parameters;
CLEAR: p_aaa, p_bbb, p_ccc.
I debugged and control passes through this code but still the fields are not cleared and they retain the old input values.
How to clear them ?
thnks

IMO, he only wants to clear the selection screen parameters on the click of 'BACK' button
in the list screen. If the OP clears the selection screen variables in AT SELECTION-SCREEN OUTPUT
even, the values assinged to the selection parameters in the INITIALIZATION and with the DEFAULT addition of the PARAMETERS and SELECTION-OPTIONS statements will also be overwritten even when the report is executed for the
first time.

ODI - How to clear a slice before executing the data load interface

Hi everyone,
I am using ODI 10.1.3.6 to load data daily into an ASO cube (version:11.1.2.1). Before loading data for a particular date, I want the region to be cleared in the ASO cube defined by "that date".
I suppose I need to run a PRE_LOAD_MAXL_SCRIPT that clears the area defined by an MDX function. But I don't know how I can automatically define the region by looking at several coloums in the data source.
Thanks a lot.

Hi, thank you for the response.
I know how to clear a region in ASO database. I wrote a MaxL like the following:
alter database App.Db clear data in region '{([DAY].[Day_01],[MONTH].[Month_01],[YEAR].[2011])}'
physical;
I have 3 seperate dimensions such as DAY, MONTH and YEAR. My question was, I don't know how I can automize the clearing process before each data load for a particular date.
Can I somehow automatically set the Day, Month, Year information in the MDX function by looking at the day,month,year coloumns in the relational data source. For example if I am loading data for 03.01.2011, I want my MDX function to become {([DAY].[Day_01],[MONTH].[Month_03],[YEAR].[2011])}'. In the data source table I also have seperate coloumns for Day, Month , Year which should make it easier I guess.
I also thought of using Substitution variables to define the region, but then again the variables need to be set according to the day,month, year coloums in the data source table. I also would like to mention that the data source table is truncated and loaded daily, so there can't be more than one day or one month etc in the table.
I don't know if I could clearly stated my problem, please let me know if there are any confusing bits.
Thanks a lot.

How to clear a private static class attribute once it's been created?

<pre>I'm working with an instance of a complex Class object that has been created using the function module HRXSS_CAT_APPLICATION_INIT. The Class object that I am trying to work with is CL_XSS_CAT_BUSINESS_LAYER and in particular its Static Private component attribute PROFILE. 
The issue that I am having is that the first call of this function module creates and populates the Static Private component attribute, PROFILE, for the instance of this Class and I do not know how to initialize it once it's been created. The PROFILE attribute is an object reference to an instance of Class CL_XSS_CAT_PROFILE. 
I want to reset/intialize this Static Private component. I can then call a Class Method with different parameters so that it repopulates PROFILE with different attributes. There is no Public method to do this in CL_XSS_CAT_BUSINESS_LAYER and even the Private method INIT_PROFILE, the logic first checks to see if the PROFILE component is initial before creating a new PROFILE object instance. All the Attributes of the CL_XSS_CAT_PROFILE object are Static and Private.
 
I would appreciate any insight anyone might have in how to reset/initialize this Class component attribute. 
Thanks much, 
 
Graham

OK...I apologize but I did not dig deep enough to see that the Enhancement Framework allows for the addition of Methods to Classes/Interfaces. Most of this ABAP OO stuff is still quite new to me so I'm struggling with syntax and what is and isn't possible based on how everything is declared. I guess now that I know I can do this I am having some problems understanding how singleton Class objects work and how to 'reset' them.
The Class instance based on CL_XSS_CAT_BUSINESS_LAYER has a Static Private attribute PROFILE that is an object reference to the singleton Class instance CL_XSS_CAT_PROFILE.
The singleton Class instance of CL_XSS_CAT_PROFILE has all of its attributes set to Static Private. If you look at this Class in SE80 you see that one of its attributes is also called PROFILE and is an object reference variable to itself.
So the issue I am having is how to go about 'initializing' this singleton object so that I can 'recreate' this singleton object using a copy of the existing S
I used the enhancement framework to create a copy of the CL_XSS_CAT_BUSINESS_PROFILE Instance Private Method INIT_PROFILE , called in INIT_PROFILE2, but I am not sure how to 'clear/reset' the instance of the CL_XSS_CAT_PROFILE object.
Since PROFILE is an attribute of the CL_XSS_BUSINESS_LAYER object, I thought that a simple CLEAR PROFILE would reset the object but this is not the case. Within this method the FREE clears the value of the reference variable PROFILE but as soon as you step into the method me->init_profile, the value of PROFILE goes back to what it was. I need for all of the CL_XSS_CAT_PROFILE instance attributes to be reset or initialized so I can fill them again. I think I'm getting confused on the scope of things...should I be enhancing the CL_XSS_CAT_PROFILE Class with 'setter' methods so I can initialize all of the Static Private attributes that way instead of trying to clear all the attributes at a higher call level?
Any assistance with helping me with my thought process or approach to this would be much appreciated.
METHOD INIT_PROFILE2.
FREE PROFILE. >>> is reset but it does not carry through to next method call and does not clear all the attributes of the object referenced in PROFILE
CALL METHOD me->init_profile

IM_PROFILE_ID = im_profile_id

How can I change Connection parameters when promoting to Production ???

Hi Everyone !
Do you know how can I change Connection Framework parameters in a Webdynpro Application? The app was deployed in TEST, now I want to move it to Production...
In my application I am using Connection Framework to connecto to a BAPI.
The connection was created using
SAP Connectivity > SAP Enterprise Connector.
I provided connection parameters for a TEST environment (Host name, system number, client, logon name...).
I deployed the application in TEST, but how can I change these parameters prior to promote it to Production? Were and how do I fill the new parameter values?
Many Thanks,
Silvio Hirashiki

Hi Silvio,
AFAIK, you need to provide JCO connection to proxy port type and all connection specific data is there. (http://help.sap.com/saphelp_nw04/helpdata/en/ed/897483ea5011d6b2e800508b6b8a93/frameset.htm). You can use configuration files for this or RFC destination.
You only need to regenerate proxy when interfaces of functional modules are dufferent for TEST and Production.
BTW, why are you using SAP EC instead of adaptive RFC model in WD application?
Best regards, Maksim Rashchynski.

How to clear outbound Queue in SXMB_MONI

HI Experts,
Unable to process the file in SXMB_MONI as a result the files are getting strucked with the QUEUE and now how to clear this queues for processsing the file...
and another i have configure the server with 611 client but while executing the client of the server is showing 001 and we didn't observe initially as it is working fine but when we observed now it is found
is this has an impact..
do we need to do any other certain configurations at the Server end..
regards,
Kishore

> There is no URL in SXMB_ADM, how to provide an url there, and even before we didn't get this problem as the files are successfully processsing for the past 3 months in PDN, and now we are getting this problem.
>
Hello,
I have understood your problem but you are not following the steps which we are mentioning here.
For your above problem you need to follow ONLY step no1 & 2 mentioned in the blog since steps are common for acitvating the proxy and thats way you are getting confused that why I am asking you to follow that blog.
In the blog step 1 will simply help you creat the RFC destination.
Step 2 will help you to use the above RFC destinaiton as an url.
In opionion if you resolve this problem first then it will be easier to solve your queue problem.
Please let me know if you need more help/clarification in this regard i will help you.

How does one pass import parameters to a report within a method?

Hello all,
Well how does one pass import parameters to a report which is within a method ...end method.
for example :
method 123
SUBMIT reportname using selection '1000'
endmethod .
Here we need to pass values into the selection screen and run the report for those values.
The values are say 'ABC' ( tablename "DEF" and field name "HIJ" ).
I hope the question is clear, awaiting your response
Thanks and Regards,
Sandeep.

Go to SE24
Parameters: Give the Parameter name, Typing method is "Type" is the domain type that u are selecting, say for e.g : Parameter is "P_CONT" , its associated type "CHAR32" etc
For Select Options: Parameter name say "S_CUST", Type"importing". For this you need to give an associated type which must be created as "TABLE TYPE " in SE11. That table type needs to have a "LINE TYPE" .
LINE TYPE is a Structure created with components "SIGN, OPTION, LOW & HIGH" for select-Options.
NOTE: for a Table type related to Customer data fields "say KUNNR", the line type created must have the Component Type and data Type corresponding to the Data Element associated with "KUNNR" ;i.e: "CHAR" etc.
See if this is clear to you or revert back in case of any Confusion.
