Differences Btw. Counter Gate and Source Channels

I am working with a Flow Technology Turbine Flowmeter. It has a 30mv-300mv sine wave signal. I want to convert this signal into a usable pulse signal. I am trying to look for information on connecting this signal to the counter channel of my PCI card. What is the differences between the counter gate and source channels. If anyone knows where I can get this information, please let me know.

Hm. You seem to be asking two different questions:
1) Counter gate and source terminals.
It would depend on the exact hardware, but the source terminal would generally be the one that causes the counter to increment/decrement its count. The gate would control whether the source is allowed to do that. Some counter chips use the gate for more sophisticated counter control.
The best place to learn about counter/timer functions would probably be the NI-DAQmx Help that installs along with NI-DAQmx.
2) How to convert 30-300 mV sine wave to pulses. I take it that its the frequency of the sine wave that you're after.
This isn't a job for a counter. A counter requires a well-conditioned digital signal satisfying the rise-time and voltage levels of a digital signal.
You probably need to scan your signal with an analog input and then post-process it to calculate the frequency. There are a number of ways to do that- the simplest would probably be to look for zero crossings in the analog signal. I don't know Labview, but I bet there's a canned vi to do just that.Message Edited by WM John Weeks on 12-13-2005 09:08 AM

Difference betwin Allacation sttucture and source structure

< MODERATOR: Message locked. Please post in the correct forum. >
Hi friends any one explian the difference betwin allocation structure and source structure.

Hi
allocation structure defines the cost elements to be settled by cost elements. A source assignment is assigned to the allocation structure.
The source structure is used to settle costs incurred on the sender to various receivers, split by cost element. In this way, the source information is retained.
The source assignment defines the assignment of the debit cost element(s) to a receiver. More than one source assignments are summarized in one source structure

Difference btw idoc ale and edi

Hi all,
I'm a beginner in abap, can anyone send me the concepts of ALE, IDOC and EDI and the difference btw all the three.
Also do send some materials for the same.

Hi,
ALE (Application Linking and Enabling)
Ale Technology is SAPs technology to support distributed yet integrated processes across several SAP systems.
Distributed Process:
A distributed process is one in which part of a business process is carried out on one system and part on another. The two systems would exchange data with each other at appropriate points to stay synchronized.
Need for Distributed Process:
Business in Different Geographical Locations.
Non availability of dedicated network.
Cultural and language differences in Geographical locations.
Running of Mission-critical Applications (Like Maintenance downtime etc.).
Separate up gradation of Modules.
Distributed SAP SYSTEM CHALLENGES
A system that understands the syntax and semantics of the data. It was important from the very beginning to base the distribution of data on business rules, not on database replication techniques.
Distributed systems that can maintain their autonomy while being integrated as one logical SAP system. The systems should be able to operate independently and support logical processing of transactions and data.
Distributed systems that can handle different data models. A local implementation should be able to customize the system to meet its local needs.
Receiving systems that can handle their own problems and not tie up the sending system.
Systems that maintain continued operation in spite of network failure. Changes made to either system should be synchronized after the network connection is restored.
A sound technology and methodology that can be used in all distribution scenarios.
SAP Distributed environment:
ALE allows for efficient and reliable communication between distributed processes across physically separate SAP systems.
ALE is based on application to application integration using messaging architecture. A message defines data that is exchanged between two processes. IDocs are containers that hold data exchanged between the two systems.
Benefits of ALE:
Integration with non-SAP systems: ALE architecture allows third party applications to integrate with SAP system.
Reliable Distribution: Once message type created and the receiver of the message is determined, ALE delivers the message to the recipient. If there is any network problem it will buffer the message and delivers the message once the network is restored. It also ensures that the message is not delivered twice.
Release Upgrade: Any of the distributed system can be upgraded to the new release of SAP without affecting the functionality. The ALE layer ensures backward compatibility of messages exchanged between systems.
ALE Architecture:
It consists of an Outbound process, an Inbound process, and an Exception Handling process.
Outbound Process:
ALE Outbound Process in SAP sends data to one or more SAP Systems. It involves four steps.
1. Identify the need of IDoc: This step starts upon creating a application document, can relate to a change to a master data object.
2. Generate the Master IDoc: The document or master data to be sent is read from the database and formatted into an IDoc format. This IDoc is called as a Master IDoc.
3. Generate the Communication IDoc: The ALE Service layer generates a separate IDoc from the Master IDoc for each recipient who is interested in the data. Separate IDocs are generated because each recipient might demand a different version or a subset of the Master IDoc. These recipient-specific IDocs are called Communication IDocs and are stored in the database.
4. Deliver the Communication IDoc: The IDoc is delivered to the recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receiver or process the IDoc.
Inbound Process:
The inbound process receives an IDoc and creates a document in the system.
1. Store the IDoc in the database: The IDoc is received from the sending system and stored in the database. Then the IDoc goes through a basic integrity check and syntax check.
2. Invoke the Posting Module: The control information in the IDoc and configuration tables are read to determine the posting program. The IDoc is then transferred to its posting program.
3. Create the Document: The posting program reads the IDoc data and then creates a document in the system. The results are logged in the IDoc.
Over view of IDocs:
IDoc is a container that is used to exchange data between any two processes. The document represented in an IDoc is independent of the complex structure SAP uses to store application data. This type of flexibility enables SAP to rearrange its internal structure without affecting the existing interface.
IDoc interface represents an IDoc Type or IDoc data. IDoc Type represents IDocs definition and IDoc Data is an instance of the IDoc Type.
IDoc Types:
IDoc type structure can consist of several segments, and each segment can consist of several data fields. The IDoc structure defines the syntax of the data by specifying a list of permitted segments and arrangement of the segments. Segments define a set of fields and their format.
An IDoc is an instance of an IDoc Type and consists of three types of records.
i. One Control record: each IDoc has only one control record. The control record contains all the control information about an IDoc, including the IDoc number, the sender and recipient information, and information such as the message type it represents and IDoc type. The control record structure is same for all IDocs.
ii. One or Many Data records: An IDoc can have multiple data records, as defined by the IDoc structure. Segments translate into data records, which store application data, such as purchase order header information and purchase order detail lines.
iii. One or Many Status records: An IDoc can have multiple status records. Status record helps to determine whether an IDoc has any error.
Message in IDoc Type:
A Message represents a specific type of document transmitted between two partners.
Outbound Process in IDocs:
Outbound process used the following components to generate an IDoc. A customer model, and IDoc structure, selection programs, filter objects, conversion rules, a port definition, an RFC destination, a partner profile, service programs, and configuration tables.
The Customer Model:
A customer model is used to model a distribution scenario. In a customer model, you identify the systems involved in a distribution scenario and the message exchanged between the systems.
Message control:
Message control is a cross application technology used in pricing, account determination, material determination, and output determination. The output determination technique of Message control triggers the ALE for a business document. Message control separates the logic of generating IDocs from the application logic.
Change Pointers:
The change pointers technique is based on the change document technique, which tracks changes made to key documents in SAP, such as the material master, customer master and sales order.
Changes made to a document are recorded in the change document header table CDHDR, and additional change pointers are written in the BDCP table for the changes relevant to ALE.
IDoc Structure:
A message is defined for data that is exchanged between two systems. The message type is based on one or more IDoc structures.
Selection Program:
Is typically implemented as function modules, are designed to extract application data and create a master IDoc. A selection program exists for each message type. A selection programs design depends on the triggering mechanism used in the process.
Filter Objects;
Filter Objects remove unwanted data for each recipient of the data basing on the recipients requirement.
Port Definition:
A port is used in an outbound process to define the medium in which documents are transferred to the destination system. ALE used a Transactional RFC port, which transfers data in memory buffers.
RFC Destination:
The RFC destination is a logical name used to define the characteristics of a communication link to a remote system on which a function needs to be executed.
Partner Profile:
A partner profile specifies the components used in an outbound process(logical name of the remote SAP system, IDoc Type, message type, TRFC port), an IDocs packet size, the mode in which the process sends an IDoc (batch versus immediate), and the person to be notified in case of error.
Service Programs and Configuration Tables:
The outbound process, being asynchronous, is essentially a sequence of several processes that work together. SAP provides service programs and configuration tables to link these programs and provide customizing options for an outbound process.
Process flow for Distributing Transactional Data:
Transactional data is distributed using two techniques: with Message control and without message control.
Process flow for Distributing Master Data:
Master data between SAP systems is distributed using two techniques: Stand alone Programs and Change Pointers.
Triggering the Outbound Process via Stand-Alone Programs:
Stand-Alone programs are started explicitly by a user to transmit data from one SAP system to another. Standard Programs for several master data objects exist in SAP. Ex. The material master data can be transferred using the RBDSEMAT program or transaction BD10.
The stand-alone programs provide a selection screen to specify the objects to be transferred and the receiving system. After the stand-alone program is executed, it calls the IDoc selection program with the specified parameters.
Triggering the Outbound Process via Change Pointers:
The change pointer technique is used to initiate the outbound process automatically when master data is created or changed.
A standard program, RBDMIDOC, is scheduled to run on a periodic basis to evaluate the change pointers for a message type and start the ALE process for distributing the master data to the appropriate destination. The RBDMIDOC program reads the table TBDME to determine the IDoc selection program for a message type.
Processing in the Application Layer:
The customer distribution model is consulted to make sure that a receiver has been defined for the message to be transmitted. If not, processing ends. If at least one receiver exists, the IDoc selection program reads the master data object from the database and creates a master IDoc from it. The master IDoc is stored in memory. The program then calls the ALE service layer by using the function module MASTER_IDOC_DISTRIBUTE, passing the master IDoc and the receiver information.
Processing in the ALE Interface Layer:
Processing in the ALE Layer consists of the following steps:
Receiver Determination: The determination of the receiver is done through Customer Distribution Model.
IDoc Filtering: if an IDoc filter is specified in the distribution model for a receiver, values in the filter are compared against the values in the IDoc data records. If a data record does not meet the filter criteria, it is dropped.
Segment Filtering: For each sender and receiver combination, a set of segments that are not required can be filtered out.
Field conversion: Field values in data records are converted by using the conversion rules specified for the segment.
Version change for segments: Segments are version-controlled. A new version of a segment always contains fields from the preceding version and fields added for the new version. Release in IDoc type field of the partner profile to determine the version of the segment to be generated.
Version change for IDocs: IDocs are also version controlled. The version is determined from the Basic Type field of the partner profile.
Communication IDocs generated: The final IDoc generated for a receiver after all the conversions and filtering operations is the communication IDoc. One master IDoc can have multiple communication IDocs depending on the number of receivers identified and the filter operations performed. IDoc gets the status record with a status code of 01 (IDoc Created).
Syntax check performed: IDoc goes through a syntax check and data integrity validation. If errors found the IDoc get the status of 26 (error during syntax check of IDoc Outbound). If no errors found the IDoc gets the status 30 (IDoc ready for dispatch ALE Service).
IDoc dispatched to the communication Layer: In the ALE process, IDocs are dispatched using the asynchronous RFC method, which means that the sending system does not await for data to be received or processed on the destination system. After IDocs have been transferred to the communication layer, they get a status code 01 (Data Passed to Port OK).
Processing in the Communication Layer:
To dispatch an IDoc to a destination system, the system reads the port definition specified in the partner profile to determine the destination system, which is then used to read the RFC destination. The RFC destination contains communication settings to log o to the remote SAP system. The sending system calls the INBOUND_IDOC_PROCESS function module asynchronously on the destination system and passes the IDoc data via the memory buffers.
Inbound Process in IDocs:
An inbound process used IDoc structure, posting programs, filter objects, conversion rules, a partner profile, service programs, and configuration tables to post an application document from an IDoc.
Posting Program:
Posting programs, which are implemented as function modules, read data from an IDoc and create an application document from it. A posting program exists for each message. Each posting program is assigned a process code. A process code can point to a function module or a work flow. In the standard program process codes always point to a function module.
Ex. The posting program for message type MATMAS is IDOC_INPUT_MATMAS which has a process code MATM.
Workflow:
A workflow represents a sequence of customized steps to be carried out for a process. The workflow management system is used to model the sequence, identify information required to carry out the steps and identify the person responsible for the dialog steps.
Partner Profile;
A partner profile specifies the components used in an inbound process (partner number, message type, and process code), the mode in which IDocs are processed (batch versus immediate), and the person to be notified in case of errors.
Process flow for the Inbound process via a Function Module:
In this process, IDocs are received from another system and passed to the posting function module directly.
1. Processing in the communication Layer:
The IDOC_INBOUND_ASYCHRONOUS program, triggered as a result of an RFC from the sending system, acts as the entry point for all inbound ALE processes. The IDoc to be processed is passed as an input parameter. Control is transferred to the ALE/EDI layer.
2. Processing in the ALE/EDI Interface Layer:
Basic integrity check: A basic integrity check is performed on the control record.
Segment Filtering and conversion: Filtering out unwanted segments and carry out any required conversion of field values.
Creation of Application IDoc: The application IDoc is created and stored in the database and a syntax check is performed. If there are errors it gets status code of 60 (Error during Syntax check of IDoc Inbound). At this point a tangible IDoc, which can be monitored via one of the monitoring transactions, is created and the IDoc gets status code 50 (IDoc Added).
IDoc Marked ready for Dispatch: IDoc gets the status code 64 (IDoc ready to be passed to application).
IDoc is passed to the posting program: The partner profile table is read. If the value of the Processing field is set to Process Immediately, the IDoc is passed to the posting program immediately using the program RBDAPP01.
3. Processing in the Posting Module:
The process code in the partner profile points to a posting module for the specific message in the IDoc. The posting program implemented as a function module either calls a standard SAP transaction by using the Call Transaction command for posting the document or invokes a direct input function module.
The results of execution are passed back via the function modules output parameters. If the posting is successful IDoc gets the status code 53 (Application Document Posted) or it gets status code 51 (Error: Application Document Not Posted).
IDOC:
Data Creation in Idoc
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an
asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.
While IDocs have to be understood as a data exchange protocol, EDI and ALE are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to deliver data to the receiving system. ALE is basically the scheduling mechanism that defines when and between which partners and what kind of data will be exchanged on a regular or event triggered basis. Such a set-up is called an ALE-scenario.
IDoc is a intermediate document to exchange data between two SAP Systems.
*IDocs are structured ASCII files (or a virtual equivalent).
*Electronic Interchange Document
*They are the file format used by SAP R/3 to exchange data with foreign systems.
*Data Is transmitted in ASCII format, i.e. human readable form
*IDocs exchange messages
*IDocs are used like classical interface files
IDOC types are templates for specific message types depending on what is the business document, you want to exchange.
WE30 - you can create a IDOC type.
An IDOC with data, will have to be triggered by the application that is trying to send out the data.

An IDoc is simply a data container that is used to exchange information between any two processes that can understand the syntax and semantics of the data...
1.IDOCs are stored in the database. In the SAP system, IDOCs are stored in database tables.
2.IDOCs are independent of the sending and receiving systems.
3.IDOCs are independent of the direction of data exchange.
The two available process for IDOCs are
Outbound Process
Inbound Process
AND There are basically two types of IDOCs.
Basic IDOCs
Basic IDOC type defines the structure and format of the business document that is to be exchanged between two systems.
Extended IDOCs
Extending the functionality by adding more segments to existing Basic IDOCs.
To Create Idoc we need to follow these steps:
Create Segment ( WE31)
Create Idoc Type ( WE30)
Create Message Type ( WE81)
Assign Idoc Type to Message Type ( WE82)

EDI:
Electronic Data Interchange
Cross-company exchange of electronic data (for example business documents) between domestic and international business partners who use a variety of hardware, software, and communication services. The data involved is formatted according to predefined standards. In addition to this, SAP ALE technology is available for data exchange within a company.

EDI FLOW :
Here is some thing which helps you and here the purchase order is taken as example too..
Electronic Data Interchange, or EDI, is the electronic exchange of business data. Using a standard format, EDI provides a method of transmitting business data from one computer to another, without the need to re-key data. This electronic link can result in more effective business transactions. With EDI, paper documents such as invoices can be replaced with electronic transmissions, thus time is saved, and the potential for error is minimized. Data can be exchanged at any time. Related business expenses, such as postage, printing, phone calls, and handling, can also be significantly reduced. EDI can aid in the support of manufacturing efforts, such as Just-in-Time and Third Party Warehousing, and financial efforts, such as Electronic Payments.
What parts of the business cycle can be supported by EDI?
Any business documents that are currently exchanged using paper can be converted to an EDI. Standards. Standards include ANSI X12 and XML/EDI are primarily used in the United States, while EDIFACT is used in Europe and Asia.
How does EDI get started?
EDI gets started when one company contacts another expressing interest in trading business documents electronically using Electronic Data Interchange. The two companies must first determine each other's EDI capabilities. If you do not already know your EDI capabilities, we have prepared a questionnaire to help you determine them. If you are already EDI capable, we will coordinate with your technical staff to determine a testing plan. Upon completion of testing the EDI documents, the appropriate business personnel will set a production start date to begin the exchange of EDI business data. If you are not EDI capable, we recommend you first obtain a commitment from your upper management. Your company will need to allocate resources and capital for software, hardware, testing, possible programming, and training.
What is the flow of EDI?
The flow of EDI depends on the sophistication of your systems and your EDI software. If you have internal purchasing/order entry systems, you will need interface programs that can extract and insert data out of and into these systems. EDI programs that interface with your internal systems are preferred over software that requires re-keying of data. Embassy Software specializes in seemless interface between EDI and your back office systems. Using a purchase order as an example of a business document your customer would send that PO electronically (850) to you. It could be sent either through a VAN (Value Added Network) or through an FTP server. You would take that 850 and convert it either into and ODBC database, a flat file or XML document to be imported into your Order System with the use of EDI Software such as PassportXchange.. Using EDI communication software, which is part of the PassportXchange package you would pull down data at set intervals from the VAN or FTP. These documents are then processed through EDI translation software and output to our order entry system. Finally, an EDI document called a functional acknowledgment (997) is sent to your customer.

Difference between Trunk links and port channel

Can anyone please explain me the difference between the Trunk links and Ether channel ?

As the other posters have already described, in Cisco parlance, a "trunk" is a link that carries VLAN tagged frames. (Note, Cisco has two technologies for these, ISL [old/proprietary] and IEEE 802.1Q [vendor independent].) An Etherchannel (also called a port-channel) is one logical link that includes one or more physical links. (Note, although Etherchannel can run across just one link, normally more than one link is configured. Older and most Cisco implementations support up to 8 links in one channel bundle. There's also multiple Cisco technologies that support Etherchannels, such as manual/PAgP[Cisco/old]/LACP[IEEE 802.3ad].)
Trunk links might also be configured on an Etherchannel link.

Difference btw cf8 standard and enterprise

hi,
i've downloaded the pdf from adobe website stating the
difference btw standard and enterprise edition. But i'm quite
puzzled on this:
Enterprise feature that runs through the Enterprise Feature
Router (EFR). These features will run in the Standard
Edition. However, all features running through the EFR will
be limited to one shared simultaneous request.
What is EFR? And does it mean that for standard edition, all
the tags fucntion remains the same except that it only allow 1
request of such tag at 1 time?

"What is EFR? And does it mean that for standard edition, all
the tags
fucntion remains the same except that it only allow 1 request
of such
tag at 1 time?"
For the effected functionality. This does not apply to all
Standard
Functions, just new Standard Functions that previously where
Enterprise
only such as gateways. Standard not has gateways, but only
one at a
time. I believe the same applies to some of the advanced PDF
functionality and similar features.

What's difference btw. Dreamweaver and photoshop

What is the difference between Dreamweaver CS4 and Photoshop
CS4? I am not sure which to purchase.

Dreamweaver is for creating web pages. Photoshop is for
editing creating
graphics. Fireworks is for creating graphics specifically for
use on the
web. The graphics would be used in Dreamweaver as you are
building the
page's HTML, and adding its interactivity.

Counter output 2V when using gate and source at the same time..

I'm using NI TIO-6601.
I connected output of counter_0 to pfi 34 and pfi27 on hardware(CB-68LP).
pfi 34 is used for gate to counter_1 and counter_2.
With this gate, counter_1 and counter_2 generate pulse trains when the gate is in high state.
pfi 27 is used for source to counter_3.
With this source, I'm trying to let counter_3 count event on counter_0.
However, after this connection, the voltage from counter_0 is about 2V measured by Oscilloscope.
Also, counter_3 cannot count the event on counter_0.
Is there any problem on my connection ? or any tips for solving this problem??
Thanks in advance!!
p.s. It works when only two counters are working.
for example, when counter_0 generates pulse tra
in and output is connected to pfi_27, then counter_3 can count the event on counter_0.
Thanks again!

Hello,
Thank you for contacting National Instruments.
This issue may be related to amount of current the output of counter 0 can produce. You may want to try a different method for making these connections. Try routing your counter 0 output on to RTSI line 1. Then use RTSI1 as the gate for counters 1 and 2 and the source for counter 3. This way, you will not need to use two seperate PFI connections.
If you are using Trad. DAQ and LabVIEW you will need to use the Route Signal.vi. If you are using DAQmx, you will need to use the Export Signal.vi

Difference btw front office and CIC

Gurus,
I'm new to IS-U, I want to know the basic difference between Front office ES20 and customer Interaction center CIC0.
Do CIC is similar to IC-Webclient interaction center available in CRM?
When the client will go for front office and CIC.
Thanks in advance....
James....

Hi James,
CIC0 in ISU is very much different from the CRM IC client. CRM has its own database and you can have lots of functionality with the CRM IC like prospects and many more.
ES20 does not suits it is used by the Customer Care Representatives.
CICO or EC70 in ISU can be used by the Customer Care Representatives if there is not much functionality for the client. Like simple move in and Move OUt is happening. ( Good for Distributors Clients )
But if there are functionlities that the Customers are given offers and different plans so that they donot leave the services. Then it is possible through CRM IC . Best suited for Retailer Clients as they dont want to loose the customer
Please let me know iin case of any query.
Regards,
Manish

Difference between count(col_nm) and count(*)

Hi i tried the following
create table chknull (a )
as select 1 from dual union all
select 2 from dual union all
select null from dual And i selected the values which are not null
select count(*) from chknull where a is nullReturns me 1 record
But
select count(a) from chknull where a is nullReturns me 0 record
Why it returns like above;
Could you please give me the hint in this
Thanks

Count(<expression>) where expression is a column, a literal or a calculation, counts all non-null occurences of the expression. Since your column a is null, the count of non-null occurences of the expression is zero. Count(*) is a special case of count(<expression>) where the expression evaluates to a row. So, as long as the row exists count(*) will count it.
Consider:
SQL> WITH t AS (
2     SELECT 1 id, 'A' name FROM dual UNION ALL
3     SELECT 2, 'B' FROM dual UNION ALL
4     SELECT 3, null FROM dual)
5 SELECT count(*) star, count('Banana') literal, count(name) col,
6         count(case when mod(id, 2) = 0 then 1 end) calulation
7 FROM t;
      STAR    LITERAL        COL CALULATION
         3          3          2          1John

Difference BTW 4.6c and 4.7

Hi,
can any 1 give the main differences between 4.6c version and 4.7 version.
i am not finding major differeces between these.
please help on this.
regards,
KBS Reddy

Hi,
In 4.7 you can mark programs unicode enabled.
I feel that is major difference.
And while wrtiing programs also in editor in 46C
72 chrs only in 47 it is 255 chrs (length of the
editor).
If you debug any program all are developed using object oriented programming.
Some of the function modules like ws_upload , ws_downlaod are absolate to use in 4.7. you should use
gui_upload..etc.
I feel these are some differences....may be lot more...
are thre.
Thanks & Regards,
Siri.

Difference in count(*) query and select * query results

i am using Oracle9i Enterprise Edition Release 9.2.0.8.0.
in a table select count(*) returns 34, but when i run select * statement it returns only 6 rows. Results are pasted below. Can any one knows the reason of this mismatch
SQL> select * from pay_at;
EMP_CODE STA IN_OUT_DA TIME
100341 IN 07-MAR-04 09:32
100341 OUT 07-MAR-04 10:24
103165 IN 31-MAR-03 14:41
103165 OUT 31-MAR-03 20:00
101204 IN 19-APR-04 13:00
101204 OUT 19-APR-04 23:59
6 rows selected.
SQL> select count(*) from pay_at;
COUNT(*)
34
------------------------------------------------------

Maybe you pressed CTRL-c during the fetch phase of "select * from" ?
If this is not the case, try to build a very small test case we can run that shows this behaviour and post it here.

Rob.

You can read :
Followup August 31, 2001 :
I'll have to guess, since you don't say, that you are using 7.x and before when count(*) and count(1) were different (and count(1) was slower). In all releases of the databases for the last 4-5 years, they are the same.
Don't waste your time on that.

What is difference btw project Assignment, Resource Assignment and task Assignment.

Hi,
I am new project accounting Module .
what is difference btw project Assignment, Resource Assignment and task Assignment.

Project Assignment, Resource Assignment refers to the resource management part and Task assignment is basically the work assignment to the resource.
An assignment/requirement is created in PJR for create demand for the resource requirement of the project and when the resource is aligned he can be assigned to the task in the work plan.
Refers to the top down approach in this case.
Additionally a resource can be assigned to the work plan and a assignment can be created to get the resource allocated to the project.
Refers to the bottom up approach in this case

Standard report which gives Record count of ODS, Cube and Source system.

Hi-
Is there any standard report which gives the record count of ODS, Cube and Source system?
or
If any one has ABAP program which takes care of record count pls let me know.
Thanks in advance

I don't understand. You need to check the data loads. What for do you want a list of ODS, Cubes and sources systems?
You can use messages from process chains to monitor the data loads.
You can also use an abap program inside teh process chains to save data into a table and then an abap report to see if everything went OK.
But, thinking again, you may be able to use BW statistics to get some of the information you need. Check the help for BW statistics, it might give you an idea of what you can do.
