Local variable in report writer

how to declare local variable in report writer?

HI Oscar,
what is "local" for you? Local in the report?
Did you check the documentation?

Internal variables of report painter shouldn't be selectable

Dear collegues,
I have created two new internal variables in report writer in order to use them in planning layout of TA KP67:
- previous year: marked as internal variable: calculated as: &1CGJAHE-1 (2008)
and
- future year: marked as internal variable: calcualted as: &1CGJAHE+1 (2010).
In report painter these variables are assigned to key figures and are not shown on the selection screen again as they are calculated internally.
But in planning layout of TA KP67 cost activity planning these variables are also assigned to key figures like actual costs or fixed planned costs and are indicated as acceptable for input on the selection screen but shouldn't - so how it is possible to define internal variables in co planning layouts as really internal which do not come up if the planning layout is executed via TA KP06?
Thanks and regards,
Christian

Hello Christian,
when I understand your request correctly, you want to plan for several years like 2008, 2009 and 2010 but you just want to enter one year. Right?
For the column with the current fiscal year you can use a standard variable like GJAHR. For the other columns you define the year in the column as variable with value "GJAHR-1" (last year) and with value "GJAHR+1" (following year). On the selection screen of the planning transaction you will only have one field for the current year and the fiscal year for the other columns is calculated accordingly when you run the planning.
Hope this helps.
Cheers,
Daniela

Data Acquisition - using local variables to write data to a file

Hello,
I am running a Data Acquisition vi (currently in LabVIEW 7.1 but soon to be updated to 8.2) that collects ~100 parameters of data from several sources contained in a while loop. The current configuration (which I did not write) uses very few subVIs and writes to ~100 local variables to store each parameter. It then reads all the local variables and builds an array of all the strings, converts then to a spreadsheet string, then uses the write characters to file function to append to a datafile. I am trying to clean things up and have came up with subVIs to collect the data from the following sources:
8 serial port sources collecting btwn 8 and 20 parameters each
~15 thermocouple readings
~10 analog inputs
~20 parameters read off an ARINC 429 bus.
I have come up with a subVI to read each of the sources and have placed the subVIs in the while loop. Each subVI outputs the data that it collects in array or cluster form. I was wondering how best to write each parameter to a CSV file at between 1 and 10 Hz. Should I write each subVI output to a LV and then read them off as was done before (the difference being that I have reduced the # of LVs to ~10 vs >100?
I should add that precise timing is not that important, so if all the subVIs are not collecting simultaneously (which I understand that they won't be), it does not really matter.
Thanks.

Hi jilla,

What I think that you are saying is to turn the outputs of the 4 subVIs into inputs of a 5th subVI that writes to the data file. Correct?
Yes. It may sound like a fine-point, but I beileve it's better to create a VI specifically for formatting data - in your example, 4 arrays IN, a single string OUT. Then write the string to file as a seperate operation. GUI-displayed data can go through a similar transformation, the four arrays wired to a subVI which builds output-structures specifically for display. It's a beginner's mistake to put lots of individual controls and indicators on the screen when groups of them are naturally related (in an object-oriented sense.) Use clusters to group related controls - this will keep the diagram much cleaner.
One more question: at what point (either # of data points or frequency of data collection) does it become necessary to use queues? Thanks.
Well, there's not really a clearly definable "point". I'd say if your update-rate climbs above 100Hz, or you witness poor program or system performance, then it's time. The scenario you've described is a fairly simple acquire/display&log loop - and simple is good. Then-again people can't see/react-to updates faster than about 10Hz - so it doesn't make sense to sacrifice performance - if performance becomes an issue.
Re: queues: Queues are sometimes used to buffer data that's "produced" in one place and "consumed" in another.
Here, if/when logging data, you're logging with every DAQ. I wouldn't recommend using a queue to transport data from a "DAQ loop" to a "Logging-loop" - those functions can be in the same loop. Should/could a queue be used to get data from a "DAQ loop" to update the GUI at a lower frequency? Sure, but a Notifier might be a better choice. Further, in the (simple?) program you've described, you might use a case structure (True/False) to only update FP indicators every "X" iterations - a simple solution that doesn't require Queues or Notifiers.
Cheers!

How can I put the contents of an array into a set of write local variable clusters?

I have a set of controls that a user fills in. The controls are clustered by rows, then combined into a 1D array, then written to a file. When I read the file, I want to feed the array back into the clusters with write local variables. Is there a simple way to handle the numerous local variable clusters so I can stuff the array back into them?
Is there a better way to handle the whole issue of storing and recovering the information?
The rows are steps in a procedure, and each row (cluster) contains numerical as well as string controls.

There are many ways of doing this
You may convert all your data to strings and save as an ascii file (you have to pay attention to the file format, so you can read it properly.
Or you can use the configuration vi's, it may work in your case.
or you may use an invoke node to get all controls of the vi's, save it, then read it, without worrying about any format. I have attached a vi that uses this method.

How many ways to read and write a local variable in a called VI?

Ciao!
I'm producing my first TestStand sequence. It is called "FirstAttempt" and it is made by a single step which calls a VI. One of the first dilemmas i encountered realizing this sequence is how to read and write a local variable (created going in Variables -> Locals ('FirstAttempt') -> <right click to insert local>) in the called VI.
The first way (the only one i tried) is to create a control and an indicator on the VI front panel, connect them to their respective terminals in the connector pane and then specify (going in Step Settings -> Module) that these connectors (shown in the Parameter Name column) are linked to the local variable (selected in the Value column).
The second way (not tried) consists in using TestStand API: create a Sequence Context reference on the VI front panel, link it to a property node in the block diagram, select the property "Locals" and extract from this the local variable name and value which, i think, can be readable and writable.
So...
Are the shown ways correct?
Are there other ways?
Knowing that a "local" variable can be considered "global" within the whole sequence, is there the possibility to simply create a reference to the local variable and use the reference in the called VI block diagram in order to save space in the connector pane (if using method 1) or in the block diagram (if using method 2)?
Thanks!

Hi,
Before TestStand 3 you would use the second way you quoted as its the only way.
But now you would use the first way you quoted. You may still what to pass the SequenceContext if you were going to use the TestStand API. For TestStand 3.x and above you would use this way as the first chose. (Personnelly, I would not pass the SequenceContext into a VI if I know it was never going to be used in that VI.)
Not sure I understand your final comment, maybe you are liking it to passing the reference of a control to a subVI so that the control can be updated from within the subVI.
If this is the case and you had a situation where you had a step that was running in parallel with the rest of the steps in the sequence either as a separate thread or execution and were dependent on the contents of the local variable changing from that parallel running step, then you would have to use the API SetVal method to change the local.
Hope this is clear.

How to change the text variables for a standard report-writer report ?

I am trying to change the text variables for a report -writer report and transport the same so as to change the title page and the report output heading .I know the Report-Group 6Z02 and the library 6O1 to which it belongs.I tried using the change transaction GR32 after going to the area menu through FGRP . I try to change the text variables through but it throws an error "You chose a name in the reserved name range - try different name ".
I have also tried copying this report into another report and changing the new report . I was able to change and save the text variables . Now when I try to overwrite the original report 6Z02-001 with this new report , it does not allow that.
Let me know how I can change the text variables for the same

Can anyone please suggest me what to do here ?

Are the read and write operations atomic for an array in a local variable.

Hi,
I would like to know when you access an array in a local variable, is it an atomic operation?
Thanks,
Mat

Thanks for the comments. I agree with you. However, I my case, race conditions and synchronization are not issues. Therefore, the only thing that matters to me is that the write and read operation of the array must be atomic. I know that I can implement that with a LV2 style global but I want to avoid it if possible.
If writing and reading to an array are atomic operations then I can simply use local or global variables.
All I need to know is: Is reading or writing an array in a local variable an atomic operation?
Thanks,
Mat

How to get Variable name in output (Report Writer/Painter)

Hello Experts,
We have maintained one Repot by using Report Writer, this is the report for Cost center (periodic report), input fields are Fiscal year, Period and Cost Center. In out put system will display the selected cost center balances for individual cost element.

Add content to report (locals variable by example)

I would like to add some extra information in my TestStand V4.1 report.
Is it possible to add some text strings, values of local variable etc... ??

This doc lists several ways to go about it. Pick your poison.
http://zone.ni.com/devzone/cda/tut/p/id/8289
The best for 4.1 is to use the section titled Using Additional Results in TestStand 4.1 and Later.

Local Variable or Write VISA Icon?

Suppose that you have a control in front panel to set amplitude of generator. If you do a loop in which you desire to increse every loop the amplitude it's better use a local variable of control in front panel or Icon WRITE of VISA to do this? What is the better solution?

Solved!
Go to Solution.

Writing to the local variable in your code will do absolutely nothing in setting the instrument.

User Exit for For Variable G_Set_Formula_Exit on Report Writer

Hi SAP Experts,
I want to create user exit for formula variable for Cost Center Group with alphanumeric type ( like 1KOSET- but 1KOSET is a set variable). I will use it as one of my row formula in report writer.
There is one alphanumeric user exit example, which is Controlling Area (#S010) in GS13. SAP message said that I can create other alphanumeric user exit by using user exit G_Set_Formula_Exit.
Can someone advice on how to implement this user exit?
Your advice on this issue is highly appreciated.
Thanks,
CW

Hello Ce Wie,
Were you able to implement G_SET_FORMULA_EXIT? I am also very interested on this issue.
Thanks!

Hacer un Balance mediante report writer

Hola a todos.
Me gustaría saber como puedo crear un balance mediante report writer que me saque por meses el real en cada cuenta que le ponga y que sea navegable.
He estado probando con una biblioteca a la GTL0, pero y ratio HSL moneda local.
Seleccion general:
Clase registro     0
Ledger     0
Versión     1
Sociedad     0BBUKRS ??
Ejercicio     0BRYEAR ??
Quiero poner un mes en la pantalla de selección, y mostrar una columna con el saldo de ese mes, y 12 columnas con los últimos 12 meses.
He visto que variables para periodo con tabla glt0 hay RPMAX-0 y RPMAX-1.
El periodo RPMAX-0 me lo está haciendo bien, pero ¿como le puedo poner una columna por cada periodo: periodo-1, peridod-2, periodo-3, etc?
Muchas gracias por adelantado.
Un saludo.

Muchas gracias por todo.
Una última cosilla. Al final lo estoy haciendo con report painter e cada columna es un periodo.
0F-RP00 (Periodo) 0F-RP01 (Periodo-1) 0F-RP02 (Periodo-2) etc
¿Como cambio el ejercicio cuando pase del periodo 1 al 12?
Ahora me coge: 05-2009 04-2009 03-2009 02-2009 01-2009 ¡¡¡12-2009!!
Muchas gracias de nuevo por todo.
Un saludo.

How to solve error using local variables?

I've created a sequence with a local variable.
But when I execute it, an error occurs since the first step (before the step where I manipulate the local variable).
The error code is something like:
Error in Evaluation. Syntax expression. Column [0-0]
It's interesting because it seems that once I've executed my sequence for the first time I can't create any other sequence where this error doesn't appear.

Pparo,
The problem does not occur under TS 1.0.3 on my system. However, I think we can get to the bottom of this.
When at a breakpoint in your sequence, if I type the expression "Locals.nls == 15-" in the TestStand watch window, I will get the message
Evaluation Failed: Syntax error in expression (Column 18-18)
I believe that this is the same type of error that you have encountered. Correct me if I am wrong.
The numbers after the word "Column" indicate where the error has occurred in the expression. In your case the error occurs at the beginning of an expression. The question still remains as to in which expression is error occurring.
Are you seeing this error reported in the watch window? If so, then you have typed the expression in the watch window.
If I copy the bad expression above into a the expression of a Statement step I get a run-time error of
An error occurred in the 'Statement' step of the 'MainSequence' sequence in 'Sequence File1'.
The post-expression for the step 'Statement' could not be evaluated.
Syntax error in expression.
Error Code: -17322
From what you report, the error appears to be located in your watch expression. When I executed your sequence with a breakpoint on the first step, I added the watch expression by selected the Context tab, expanding the Sequence Context tree view until I could see the nls variable, and then I dragged nls from the tree view to the watch window. This created the watch expression of Locals.nls. I also created the same watch expression by right clicking in the watch window, selecting Add Watch from the context menu, and selecting (or typing) Locals.nls. The expressions all evaluated to 24 without error.
This process has NOTHING to do with creating local variables. You asked if you are creating variables properly. There are only 2 ways to create variables in TestStand 1.0.3, neither of which you have described. The most common method is to select the Locals tab after opening your sequence (not during execution), right click in the right pane and add the variable of your choice. It seems like you did this correctly based on the sequence file you sent. The other method of creating variables is to do so programmatically. However, this is beyond the scope of this answer.
You ask a question about "the best way to create three constants in LabVIEW and pass them to a LabVIEW VI that is a step?" This implies to me that you want to create the strings within a VI called by one sequence step, and then use them in another VI called by a different sequence step. I would recommend taking a look at the example AccessingPropertiesAndVariables.seq that ships with TestStand. The first 3 VIs write values back to step properties, but could just as easily write them back to local variables. The 4th VI writes a file reference back to a TS local variable. The 5th and 6th step get the file reference from the TS local variable. You want to do something similar to the 4th and 5th VI, however, you want to send 3 strings to local TS variables, and then get them in the following VI. This will require using "TestStand - Set Property Value (String).vi" and "TestStand - Get Property Value (String).vi" which can be found in the TestStand function palette in LabVIEW. After reviewing this example you can then ask additional question. I recommend posting the question on a different thread since it is unrelated to your original question about the syntax error.

Can OSD handle MSSQL local variables?

DECLARE @ERR_MSG VARCHAR(255);
SET @ERR_MSG = '(FOC1406) SQL OPEN CURSOR ERROR.';
SELECT *
FROM Rcaster05dev.Dbo.Botlog2
WHERE STAT_BT_NAME = 'J170547s5tlu'
AND MESSAGE like @ERR_MSG
Yields:
SELECT *
FROM Rcaster05dev.Dbo.Botlog2
WHERE STAT_BT_NAME = 'J170547s5tlu'
AND MESSAGE = @ERR_MSG
Error report:
Invalid JDBC escape syntax at line position 23 '=' character expected.
This seems like the OSD interface is getting tripped up by some of the code it's trying to pass through? Or does OSD not support local variables in MSSQL?

Hello,
I believe that SQL Developer is not faulty here. The error message seems to come from JTDS.
As a quick test, can you write a very little Java program and send the same query to your SQL Server database, using the same JTDS version that you are using in SQL Developer? If that returns with the same error message then sourceforge.net should be your next address.

Differences Between Report Painter and Report Writer

Hi,
Anyone knows the differences between report painter and report writer?
Thanks,
CW

Hello CW Teo,
Yes report writer can be used in logistics also. One of the way which I am aware of is described below.
Flexible analyses allow you to can tailor the way in which key figures are combined and aggregated. This means that it is possible to both provide administrators with detailed information and management with aggregated information.
Flexible analyses enable easy access to the Report Writer, a user-friendly tool with which you can create reports for various analyses. The Report Writer is integrated in other SAP applications, such as Extended General Ledger and Cost Center Accounting.
Evaluation structures form the interface to the Report Writer. Evaluation structures consist of characteristics and key figures and are easy to construct.An evaluation structure with the same name exists for each information structure in the standard system.Even the self-defined information structures created in Customizing can be evaluated via the flexible analyses.
Evaluations:You can create an evaluation on the basis of the evaluation structure.
To define an evaluation, all you need to do is select the characteristics and key figures you require (pick-up technique).One of the especially useful features here is that you have the option of tailoring the layout of your report to suit your particular requirements. You can also define extra key figures for the reports, which are derived from existing key figures by means of calculation formulas. You can thereby multiply the key figures or divide one key figure by another.
============================================================
In addition to the above you can also edit a report in logistics module with the help of a report writer. below mentioned is the process for it.
It is now possible to edit your report data using the Report Writer. You can also change the layout of the report. The most important functions of the layout design are summarized below.
Summation levels:In the report screen, you can use the menu sequence View ->Summation level to specify the number of summation used to calculate total values. All totals that do not lie within the specified interval will be hidden. A summation level corresponds to a hierarchical level (for example, material level). Summation level 1 is the lowest hierarchical level. Summation level 2 is the next level up, and so on. The individual values are on the summation level 0.
The summation levels can be specified both universally (for the entire report) or locally (for specific blocks of rows). In this case, the local settings overwrite global values.
Report views:If a report is displayed on the screen, the Report Writer will then set page breaks so that exactly one page fits into the current window. This view will be defined as the standard view. As the Report Writer always processes exactly one page, you can only use the page keys and page icons to page up and down; the scroll bars cannot be used.
The page view can be determined via Settings-> Page view. The page breaks in the page view correspond to those defined in the report layout.
Hide and show rows:The function Edit->Hide rows exclude certain preselected areas of your report from the display. You can undo this command with Edit ® Show rows.
Expanding and collapsing report rows:View-> Hierarchy->Collapse allows you to hide the report rows of the sub-trees that are located underneath. View->Hierarchy ->Expand allows you to undo this command level by level.
If you want to display all the report rows that were hidden by collapsing the hierarchy or restricting the summation levels, select, View->Hierarchy-> Expand all.
View->Collapse all allows you to reduced every row block to the highest summation level.
Texts and Annotations:You can create an annotation for your report.
Select: Extras->Annotation.
You branch into the text editor of the Report Writer.
Via the menu sequence Settings->Texts, you can create and format a title page, the last page, as well as headers and footers using word processing functions.
For example, you can store variables in the header for the author of the report, the date of the selection or the name of the person who last changed the report.
Layout parameters:Using the menu sequence Settings->Layout you can specify the page format, display form, rows and columns of the report according to your needs and you can determine the settings for the graphics function. You can make these layout settings with Report->Save settings.
Hope I had been able to help you to some extent. please assign points as reward.
