Using XPathMatcher (sapxmltoolkit) in a Module

Hi,
I'm writing an XI module that extracts a certain value from the XML Payload of a message and uses it for further processing.
The value is determined by an XPath that can be configured in the module's configuration.
I'm using the class XPathMatcher to evaluate the XPath. Unfortunately there is very little documentation on that API. It works as long as the XML message has no namespace associated. As soon as there is a xmlns=... in the root element, the XPathMatcher.process() method will not deliver any results.
Does anybody have experience with that class of the sapxmltoolkit or knows where to find more information (except for what's available in the <a href="http://help.sap.com/saphelp_webas630/helpdata/en/b6/8097f5a5edea4f8dfc87ac87082b22/frameset.htm">SAP Online Help</a>)
your help is appreciated,
Peter

Some months ago I asked SAP where I could find missing doc for SAPXMLToolkit, and the answer was: you're allowed to use only what's documented... meaning other stuff is not guaranteed to remain the same in the future...
That's when I decided to use
<a href="http://xerces.apache.org/xerces-j/">Apache Xerces</a>
You'll just have to include Xerces .jar files as external libs in your prj and they'll deploy along with your module.

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

**How to use Logic as a sound module with an MPC?!?!**

So I'm new to Logic, I love the program but don't know a thing about the environment... I've seen people discuss this a lot on the forums but I still haven't been able to figure it out.
Basically, I am using an MPC 2500 and would like to use Logic as a sound module.
I know you have to create a new multi track instrument in the environment but as a newbie I just can't seem to put the pieces together. I tried and tried but when I create a new instrument all I get is a box with 16 channels!?
Does someone have a similar setup? Would anyone mind sending me their environement?
MacBook Pro Mac OS X (10.4.7)

Pictures worth a thousand words and stuff:
http://bj.angeltowns.com/images/log_cs.jpg
Here I've disconnected the physical input object from the sequencer object (called "to recording & thru")
I've created a channel splitter object, and cabled the physical input object to it. I'm now in the process of option-clicking the channel splitter's output cables (one for each MIDI channel) - ()option-clicking the output cables is a shortcut way to cable to objects on different layers) - and selecting channel 1 (and thus cable 1) to go to Audio Instrument 1, channel 2 (cable 2) to Audio Instrument 2 etc.
So the MIDI comes in to Logic, gets split into individual channels, and each channel goes to it's own audio instrument via a cable, which you can put any plugins on.
You can't record into Logic this way now, as we've bypassed the sequencer, but I think you need it simple at this stage

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.
Attachments:
File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

Can I use the FP-AI-110 module for taking measures from a phototransistor ?

I wish to acquire data from a NPN phototransistor using a FP-AI-110 module. How can I do it ?
Thank you.
Marco

Well, first answer is : yes you can as AI stands for Analog Input.
I was about to add that it's quite easy, but it requires some basic knowledges about that kind of stuff !
If you already know how to use MAX (measurment and automation explorer)... If you have the appropriate documentation and the AI-110 module datasheet, then you'll be through very quickly ; if not then you'll need to learn how it works, but don't worry, lots of people did it before you
Have a try, point out accurately things you can't do alone, then come back here to ask for further help.
Have fun !

Way to use NI FieldPOint PG-522 module

Hi everybody!
I'm using for few days fieldpoint family. My needs are concerning analog inputs and pulse generation for PWM module.
For the analog inputs, everything's OK, the sample provided with CD is complete, but I have some difficulties to use PG-522 module.
My needs are to control a PWM module. Unfortunatelly, the PWM module for FieldPoint is not fast enought (I need a 2kHz signal, and FP-PWM-520 module allows only a maximum of 500Hz). That's why I decide to use Pulse Generator module with resolution of 100µs (it is constant) and I select On Time from 0 to 5, Off Time from 5 to 0, to get a real 2kHz signal.
It seems to be OK, but since I decide to use 2 channels on the module, I don't really understand how to do...
For the moment, here is the source code (LabWindows/CVI) I use to build a small dll to make it easy to control.
Here is the function I use to send OnTime and OffTime values:
int __declspec(dllexport) FP_PG_SetTime(int PG_Channel_Number, int OnTime, int OffTime)
 IAStatus status = IA_SUCCESS;
 SYSTEMTIME timestamp;
 int i;
 int temp;
 if(OnTime<0 || OnTime>5)
 temp = 5;
 else
 temp = OnTime;
 // Copy value to send with calculation of channel to control
 memcpy (PG_value + (PG_Channel_Number*4), &temp, 4);
 // Control Channel #0
 if(PG_Channel_Number == 0)
 // FP_handle, PG_value are static var, PG_On_Time_0 is the handle created with FP_CreateTagIOPoint function on the item under MAX
 if(status = FP_Write (FP_handle, PG_OnTime_0_handle, PG_value, BUFFER_SIZE))
 // Don't report errors because open current loop occurs when nothing is connected.
 if (status == 0x8181)
 Error(status);
 // Same thing for OffTime
 return 0;
Ok, now, some questions...
I don't understand why I need to open handle for each item (OnTime_0, OffTime_0,....) Because I send a value array, it should be possible to select the channel only with the memcpy operation, isn't it? If yes, how to send both OnTime and OffTime value???
The best would be to get a full sample project, but I didn't find anything on the net. Is there somebody that worked with this hardware able to explain to me how to use them as simple as possible?
Thanks a lot, and sorry for mistakes, I'm french!

Using cRIO Profibus master/slave module with Siemens device. Looking for GSD file

Using cRIO Profibus master/slave module with Siemens device. Looking for GSD file. Would NI or Siemens be able to provide this?

Hey Kurt,
For Profibus, only the slave needs to be defined with the GSD file, so you would likely get that from Siemens if their device is acting as the Slave in this setup. If you are using the NI Profibus module as a slave, then the GSD is automatically included with the driver.
Take a look at the following article for more info on how to use the included GSD file.

How to use SET & GET Parameters in Module Pool

Hi Friends,
Can anyone please tell how to use SET / GET parameters and PARAMETER ID for a text box (Input / Output field ) in module pool? What is the purpose and where do we need to do coding for it?
Note : I will definitely give the marks for good responses.
Thanks in advance,
Pradeep

Hi Pradeep,
You can save values in the SAP memory using a parameter ID. These
are user and terminal-session specific, but available to all internal and
external sessions.
SET Parameter copies the corresponding field contents into the SAP
System memory in the PAI processing block.
GET Parameter copies the corresponding field contents from the SAP
memory at the end of the PBO processing block, after data has been
transferred from the program, if the screen field still has its initial value
You can link an input/output field to an area of the SAP memory in the
ABAP Dictionary.
When you use an input/output field that is defined in the ABAP
Dictionary, its parameter ID is displayed in the Dictionary attribute
Parameter ID in the Screen Painter.
Usage
SET PARAMETER ID: CAR FIELD space,
CON FIELD space,
DAY FIELD space.
Here is the link that explains the usage of GET/SET in detail

Category ABAP Programming Error
Runtime Errors SAPSQL_ARRAY_INSERT_DUPREC
Except. CX_SY_OPEN_SQL_DB
ABAP Program SAPLBSVU
Application Component CA-GTF-TS-SMT
Date and Time 03/17/2014 07:01:29
|Short text |
| The ABAP/4 Open SQL array insert results in duplicate database records. |
|What happened? |
| Error in the ABAP Application Program |
| |
| The current ABAP program "SAPLBSVU" had to be terminated because it has |
| come across a statement that unfortunately cannot be executed. |
|What can you do? |
| Note down which actions and inputs caused the error. |
| |
| |
| To process the problem further, contact you SAP system |
| administrator. |
| |
| Using Transaction ST22 for ABAP Dump Analysis, you can look |
| at and manage termination messages, and you can also |
| keep them for a long time. |
|Error analysis |
| An exception occurred that is explained in detail below. |
| The exception, which is assigned to class 'CX_SY_OPEN_SQL_DB', was not caught |
| in |
| procedure "STATUS_UPDATE" "(FUNCTION)", nor was it propagated by a RAISING |
| clause. |
| Since the caller of the procedure could not have anticipated that the |
| exception would occur, the current program is terminated. |
| The reason for the exception is: |
| If you use an ABAP/4 Open SQL array insert to insert a record in |
| the database and that record already exists with the same key, |
| this results in a termination. |
| |
| (With an ABAP/4 Open SQL single record insert in the same error |
| situation, processing does not terminate, but SY-SUBRC is set to 4.) |
|How to correct the error |
| Use an ABAP/4 Open SQL array insert only if you are sure that none of |
| the records passed already exists in the database. |
| |
| If the error occures in a non-modified SAP program, you may be able to |
| find an interim solution in an SAP Note. |
| If you have access to SAP Notes, carry out a search with the following |
| keywords: |
| |
| "SAPSQL_ARRAY_INSERT_DUPREC" "CX_SY_OPEN_SQL_DB" |
| "SAPLBSVU" or "LBSVUU01" |
| "STATUS_UPDATE" |
| |
| If you cannot solve the problem yourself and want to send an error |
| notification to SAP, include the following information: |
| |
| 1. The description of the current problem (short dump) |
| |
| To save the description, choose "System->List->Save->Local File |
| (Unconverted)". |
| |
| 2. Corresponding system log |
| |
| Display the system log by calling transaction SM21. |
| Restrict the time interval to 10 minutes before and five minutes |
| after the short dump. Then choose "System->List->Save->Local File |
| (Unconverted)". |
| |
| 3. If the problem occurs in a problem of your own or a modified SAP |
| program: The source code of the program |
| In the editor, choose "Utilities->More |
| Utilities->Upload/Download->Download". |
| |
| 4. Details about the conditions under which the error occurred or which |
| actions and input led to the error. |
| |
| The exception must either be prevented, caught within proedure |
| "STATUS_UPDATE" "(FUNCTION)", or its possible occurrence must be declared in |
| the |
| RAISING clause of the procedure. |
| To prevent the exception, note the following: |

When i see the function module help and they are trying to COMMIT
FU STATUS_OBJECT_CREATE
Short Text
Create Status Object
Functionality
The function module generates a status object.
Take the object number from the object number management (function modules OBJECT_NUMNBER_GET_xx).
If no object number is given, the module takes a temporary object number that must be replaced later (function module STATUS_OBJECT_SWITCH_NUMBER).
Example
Creating an internal order with number 100123 (object type "ORC") for status profile "STATSCHEM" with final object number
call function 'OBJECT_NUMBER_GET_OR'
exporting
 aufnr = '100123'
importing objnr = objektnummer.
call function 'STATUS_OBJECT_CREATE'
exporting
 objnr = objektnummer
 obtyp = 'ORC'
 stsma = 'STATSCHEM'.
commit work.
Creating the same order with a temporary object number
data: objectkey like ionra.
* TBO00-REFSTRUCT for object type 'OR' is 'IONRA'
objectkey-aufnr = '100123'.
call function 'STATUS_OBJECT_CREATE'
exporting
 i_objectkey = objectkey
 obtyp = 'ORC'
 stsma = 'STATSCHEM'.
importing
 objnr = objektnummer.
call function 'OBJECT_NUMBER_GET_OR'
exporting
 aufnr = '100123'
importing objnr = objektnummer_neu.
call function 'STATUS_OBJECT_SWITCH_NUMBER'
exporting
 objnr_old = objektnummer
 objnr_new = objektnummer_neu.
commit work.
