Create a mathematical function out of samples
hello
I'd like to know how can i create a mathematical function out of
samples of a signal (sine wave for example ) .
the samples (around 1000 samples) are known( taken from a text file),
and also the time between every sample is known.
thanks a lot
Elad
What you are probably looking for is fitting experimental data to a model function.
LabVIEW has many fitting algorithms built-in and it depends on the desired function to decide what is best. You can fit to a line, polynomial, or exponential, etc., or you can use levenberg-marquardt for more complex models.
If you want to fit to a single sine function, you could use "Extract single tone".
Tell us a little more about your data.

Error while creating a simple function, procedure or triger in Oracle8i Lite
Hi,
I have Oracle8i Lite release 4.0.
While creating a simple proceudre/function/trigger on the database, it's throwing the following error:
create or replace function test return number is
ERROR at line 1:
OCA-30021: error preparing/executing SQL statement
[POL-5228] syntax error
Here is my sample code.
create or replace function test return number is
begin
return 0;
end;
Tried to create the same function in the user SYSTEM too but got the same error message.
Thanks in advance for the soluton.
nullI just started with 8i Lite, but as far as I know 8i Lite does not support PL/SQL code.
So you have to write your triggers and stored procedures in Java.

How to create a callback function module
Hi all,
I am working in a requirement where we need to call a function module at a 'after change' event. So how to create a callback function module and register it with the crmvevent ?_
I created a sample function module and try to create entries in table crmv_event_cust, but i got an error message saying that the function module name I provided is not in table CRMC_FUNC_ASSIGN. When I try to create entry there, I got a message that function module is not in CRMC_OBJ_FUNC and that table is a standard table with no maintanance options !!
looks like i am going in wrong way ... can any one please help ??Looking at my system all you need to do is create the entry for the callback function in maint view: CRMV_FUNC_ASSIGN.
Your entry should be as simple as Z-function name Object Function - <same as others in the segment you are assigning>
IE for the partner it would be CRM_PARTNER as object function, for general order processing CRM_ORDER
Take care,

Error while creating webservice from function module in ECC
Hi
while creating a web service out of a function module in ECC, in the configure service section we get a message saying ' Remember that the service does not have any runtime configuration and therefore cannot be used. Create the Web service configuration in the NetWeaver Admninistrator (transaction WSADMIN2).'
instead of check box 'release for runtime'.
Our ECC at release 7 patch level 22.
Checked in SCICM, SICF teh service and the folder are active.
Please suggest if we are missing on anything
Regards
KumarIn new version on ECC, the runtime configurations needs to be performed in transaction SOAMANGER.
On executing the transaction, it opens a browser. The important configurations to be performed are:
1. Configure J2EE server and host. You can choose to provide the ECC server and host
2. Administration of the service in "Single Service Administration". The navigation path may differ depending of the ECC versions. But it is related to administration of the services.
Once done, check the WSDL generated.
Use this WSDL in the NWDS.

Error when creating a planning function
hi,
I am creating a Planning function type using RSPLF1. Also i have created a custom class for the same. But when i try to create a planning function through RSPLAN, and using this custom planning function type, I get the following error:
Error Summary
While processing the current request, an exception occured which could not be handled by the application or the framework.
If the information contained on this page doesn't help you to find and correct the cause of the problem, please contact your system administrator. To facilitate analysis of the problem, keep a copy of this error page. Hint: Most browsers allow to select all content, copy it and then paste it into an empty document (e.g. email or simple text file).
Root Cause
The initial exception that caused the request to fail, was:

Can anyone let me know what this means and what I am missing ?Hi,
Generally these error come when we manually enter the value in the Visible and Input column. Instead we should try select value from the Drill down options which gets generated based on the Time Bucket Profile you have selected as input for Planning Horizon. -

How do I call create a public function to make something happen in another .swf
Hi guys,
I am trying to create a public function, i have a decument class with all of my variables in it, I have worked out how to bring in external .swf files, now I need a way to have an even trigger something on a separate .swf
So at the moment I have a flunction that works on the parent
stage.addEventListener(MouseEvent.MOUSE_MOVE, mousePosition);
function mousePosition(event:MouseEvent) {
if(mouseX>=125)
navigator.visible=false;
trace(mouseX);
So now how do I make this function public?
When I try to put it into my document class I get errors because the navigator MC is only on the main timeline. (not in the other swf's that I am opening)
I am trying to work out how to call the function using a string in my doc class
public var nav1:String="navigator";
Then the function
public function resetnav()
String(nav1+".visible=false;");
Which seemed like a good idea, but it doesn't work..
Can you guys help me out here?
Cheers
subHey sorry I spoke too soon, I thought my code was working but my mouse tracking code is actually working off the main timeline. I sill wan to be able to use your examples though, what is the go with psuedo code? SWF1ToSWF2Connection what is the correct dot syntax for this?

How to create the INBOUND Function Module for INBOUND IDOCs
Hi Friends,
Can any Suggest me How to proceed to Create an INBOUND Function Module for Processing the INBOUND IDOCS
which are recieved from XI Server ?
I am working in SAP-ISU
Here i will recieve the INBOUND IDOCs for the Meter Reading Orders.
We have a Standard INBOUND FUNCTION MODULE
IDOC_INPUT_ISU_MR_UPLOAD
which Uploads the Meter Reading Results.
I copied the Same function Module into ZIDOC_INPUT_
and working on it.
Can any one suggest me, whether i am going in correct way or not.
In IDOC_INPUT_ISU_MR_UPLOAD Inbound fun module,
BAPI_MTRREADDOC_UPLOAD is used to Update or Insert the Meter Reading Results,
My requirment is to Insert and Update the Meter Reading Orders which are Inbounded from XI.
Can I Use the Same BAPI
BAPI_MTRREADDOC_UPLOAD
to Update the below fields,
EABL-SERNR
EABL-ZWNUMMER
EABLG-ABLESGR
EABL-V_ZWSTAND
EABL-N_ZWSTAND
EABL-ABLHINW
EABL-ZSKIPC
EABL-ADAT
EABL-ATIMTATS
EABL-ADATTATS
EABL-ATIM
EABL-ZMESSAGE
EABL-ABLESER(Meter reader number)
Kindly Suggest me,
Thanks in Advance,
GaneshHello Ganesh
I think you are going completely astray with you z-function module for IDoc processing.
If you look at TABLES parameter METERREADINGRESULTS (type BAPIEABLU ) of BAPI_MTRREADDOC_UPLOAD you will find many of the requested fields already:
EABL-SERNR => BAPIEABLU-SERIALNO
EABL-ZWNUMMER =>REGISTER
EABLG-ABLESGR
EABL-V_ZWSTAND
EABL-N_ZWSTAND
EABL-ABLHINW
EABL-ZSKIPC
EABL-ADAT
EABL-ATIMTATS => ACTUALMRTIME
EABL-ADATTATS => ACTUALMRDATE
EABL-ATIM
EABL-ZMESSAGE
EABL-ABLESER(Meter reader number)
Field EABL-ZMESSAGE appears to be custom field (at least I cannot find it on ECC 6.0). If this field was added using include CI_EABL then you probably can get these values into the BAPI using the EXTENSIONIN parameter.
Check routine CHECK_UPLOADRECORDS in the BAPI which allows two extension structures:
- BAPI_TE_EABL
- BAPI_TE_EOSB
Not surprisingly BAPI_TE_EABL contains the include CI_EABL.

How to create a Z Function Module
Hi,
I am trying to create a Z function module in BI 7.0 that i can use in Transformations.
SE37> Name of FM.Create..>
It is prompting me to enter Function Group.
What is Function Group and How can i create a new function group (Detail Steps please)
and steps involved in creating a Function Module in BI 7.0
Thanks in AdvanceHi,
Function Group is just like a folder under which we can store n no. of function modules for organizational purpose. If u want any global declarations we will declare at function Group Level.
It is mandatory to save a function module under one function group. Select Goto menu item, select Function Group, then select, create function group in SE37. Just give the technical name and description and save.
Hope this helps u..
