Variant to Data question

This is a LV6.1 question. For an application I'm debugging, flatten data is
being used on a menu ring control. The menu ring data is unflattened using
Variant to Data. What I get back from the unflatten process is the numeric value
of the menu rings index, which is what I would expect, no problem there.
What I'd like to also get back from the unflatten process, would be the
string array of names for the menu ring that was flattened. Can someone
suggest how I can do this?

The data is only the number of the element chosen (a blue wire) and not any more data about the element. To get the list of strings you should use the Strings[] property node. Then, you can flatten and save that array.
Another option is to pass (or obtain) the reference to the ring to whereever you're using it and then use a property node to extract the data you need.
A third option is to use an enum which keeps the data inside the wire, but that means you will need to have the exact same enum on the other side (which means it probably won't help you). You can do this by making the enum a typedef.

Variant to data: Need info regarding type of data

Hello,
What I want to do is very basic. I will acquire the image using CCD camera. The
image is a raw data type: 2D array of type long (4 bytes per element) or integer (2 bytes per element). I can save the image even as .tiff file. Using Variant To Data, I am converting the image so that labview can handle it (I am not sure whether I really need this) before I write that data to some file and save it. I have to define data type for Variant To Data. I tried to define the data type. However, I am confused. Would anybody give me some suggestion?
Thanks a lot,
Dushyant

Hrm, you'll need to be more specific about your actual question in order for us to give you a good answer, but, without more information, I'd say you should just define the type as a 2-d array of either longs or words. (i.e. get an array constant, place a numeric constant inside of it, right click the numeric constant, and select Representation->Long or Representation->Word then wire the constant to the Type input of the Variant to Data).
If you're dealing with variants, I'd guess you are probably calling an ActiveX control or server to communicate with your camera?

Create a production order with variant configurator data

Hello,
Can anyone tell me the way to create a production order with variant configurator data. Is there a BAPI ? an IDOC ?
Is there several steps ?
I have to create an interface which creates automatically PP orders. The data input is a file.
Thanks for your help

Hi,
There are fews BAPI's available for creation of Production Order. They are:
BAPI_PRODORD_CREATE
This bapi will suit to your requirement, as input will be provided from file.
Others are
BAPI_PRODORD_CREATE_FROM_PLORD " this converts planned order to production order
BAPI_PRODORD_CREATE_FROM_REF " this creats production order considering other production order as reference.
Hope your query is answered.

Difference between "Database Variant To Data" and "Variant To Data"

Can anyone tell me the differnce between the 2 VI's "Database Variant To Data" and "Variant To Data"?
I am using the database connectivity toolset and making a query.
I have tried using both, but the give me the same result.

You won't see a difference between these two functions with just a string or other simple data types. Where you'll see a difference is with clusters and more complex data types that come from the database. The variants returned by databases can be slightly different than the standard variant. That is where the Database Variant To Data is needed. Otherwise, if you are just reading string information, either function will work fine.

Database Variant to Data.vi not working for the Date datatype with LV 8.2?

I'm moving a large body of LV database code from LV 7.1 to 8.2 and find that the Database Variant to Data.vi is not working correctly when used with the Date datatype. It works fine with 8.0, and the common Variant to Data works also. Am I missing something? Thanks in advance for any assistance. Wes

Thanks for the prompt reply Crystal,
The data is stored in an Oracle database using the DATE type. I'm querying many rows along with other columns and converting each of the values as necessary for each column with the 'Database Variant to Data' vi. Only conversion to Timestamp is no longer working as of version 8.2. I recognize that plain Variant to Data works but I have many (100's) of VIs to change if that is the only solution (not the end of the world). Most often the dates are originally generated in the database using PL/SQL procedures calling SYSDATE which look like: 5/1/2006 11:56:26 AM (in TOAD anyway) which I then need to read into LV as type Timestamp.

Dynamic Variant for Date Range

Making the Variant for Date or Date Range Dynamic in the Selection Screen of any Program.
There are actually many ways you can make the Variant for Dateu2019s Dynamic.
1.     Providing he Values in the Variant Variables.
2.     By creating the variables in the table TVARVC
3.     By Initializing the values in the program itself.
I saw many posts with respect to these and found that everyone has their own way of dealing. Even I wrote code in the program initialization to get this done.
Here in this post I am showing you the easiest option which is available in the Variant creation.
EX : If you want to execute the batch job based on a date range.
     SY-DATE u2013 60 days , that means always your program should execute the batch job based on System Date. And the variant should change accordingly.
Following are the step by stop to do that.
1. Select your program and select the Variant Radio button and then Click on Display.
2. It will pop up a screen with variant option below the program name.
3. Enter the Variant name and click on Create
4. You will see a screen, with the Attributes button.
5. Once you click on the Attributes button, it will take you a screen with selection option.
6. In my scenario my input is based on Calender Day, so select the Selection Variable for Calender Day: You will find 2 options T & D.
7. Select D: Dynamic date Calculation, then select the Name of Variable (input using f4). You can find many options.
8. Scroll down the Variant Attributes and select current date u2013 xxx, current date + yyy
9.Though it seems to be inactive, just double click on the row to provide the date range.
10. Just enter the value for xxx and yyy to get you dynamic range based on number of days
11. In my scenario I have to consider System Date u2013 60 days. 0 means current day.
12. Click on OK to check the range has been reflected or not. Then save the Variant and check the value by executing the program with saved Variant.
You can check the same in blog with all the screen shots attached but this thing is so easy you don't require screen shots.

Labview How to specify 1d array of clusters as data types for variant to data

Hi, I'm new to labview. Can anyone tell me how to specify 1d array of clusters as data types for variant to data?

First of all, you should be sure that there is such a data type within the variant; otherwise, you will run into errors.
I recommend you to create the cluster and create a type definition from it. Then drop an array shell from the array palette and drop the cluster type into that array.
Connect that constant to the data type input of the Variant To Data function.

How can I embed Variant To Data in a subVI and pass in the Type input?

If I use Create Control on the Type input of Variant To Data, I get an undefined type error unless I insert a control of a specific type into the cluster control that was created. This seems to prevent passing a parameter into a subVI for this purpose.

I do not see what you mean by "using it or not based on an additional input". What would the output of this function be, if it were "not used"? What exactly are you trying to do?
Personally, I have long wanted a polymorphic data type. If a polymorphic control were connected to a VI's connector pane, it would be defined by the calling VI. Once a calling VI wired a data-type to a polymorphic input of a subVI the type would propogate into the subVI.

With the release of LabVIEW 7, NI has updated App Note 154 to include some more data types (and subtypes). If you haven't seen this, I suggest you take a look.

Do you mean compound data types like clusters and arrays? Almost all data types can be decoded just fine with the available documentation. The only types that are not very straight-forward are the waveform data type, refnums, and typedefs. If you give me an example, perhaps I can help.

I don't agree. LabVIEW may add new types in new versions of LabVIEW, but fundamentally the typecodes and structure of flattened LabVIEW data types have not changed at all (even though NI does reserve the right to change this in future releases of LabVIEW). Do have specific examples of t
his?

How Variant Configuraton data from Sales Order stored in the database

Hi,
I understand that the "variant configuration" data (chosen values for each characteristics assigned to material) from a sales order is stored separately with reference of an object in SAP.
Please let me know how SAP stores such data -source in the database tables.
This is required to draw a report of these charateristics values for various sales orders (Transactional data).
I also understand that there are function modules to retrieve this data, but the function modules are unable to retrieve data as accurately as the VA03 program.
Thank you for your advice.
Regards,
Hemant

Hi ,
I do not know what a reference charactersitcs is,but there are all independant characeristics in terms of their values.
A guess it is because the VC data is changed after the sales order is created, the updated VC data is displayed properly only in VA02 or VA03 but other function modules fail to display the updated VC data.
I understand there is a relationship of instance -between sales order object and VC data object-which we need to update and then see the latest data.
Please let me know if anyone has debgged VA03 to know how the standard SAP program retrieves VC data in a sales order.
Thank you,
Hemant

Decode variant data w/o using 'Variant To Data' function.

I need to decode variant data w/o having foreknowledge of the type used to create it. That is, I'm using the 'Flattened String To Variant' function which gives me the info I need, but it's all contained within one indicator. I need some way to break this info down into its constituent elements.
For instance, let's say I have the flattened data and type descriptor from a cluster with two elements, a boolean and a string, but not the structure itself. Passing this flattened data and/or the type descriptor into a function, I would get a 2D array (or the like) as output containing the name of the boolean (its label), its value, and the name of the string and its corresponding value.
There must be a way to
do this, and I suspect it's been done already, but I can't find any reference to it.
I have attached a file named Test.vi which demostrates this problem.
Remember, even though I know the name of the control, I won't know the type, so I cannot use the 'Variant To Data' function to deference these values. I can make ready use of DLLs, CINs, or LabVIEW code for the solution.
Thanks ahead of time for any help! Greg

Test.vi ‏26 KB

You might be able to take advantage of the Variant to Flattened String VI from the Advanced>>Data Manipulation>>Variants pallette. This VI converts a Variant to a flattened data string and a type descriptor. The type descriptor is explained in ap note 154. You might be able to create a VI that would parse data from the flattened data string using the type descriptor. You might have to represent each piece of data as a flattened string to work around the data flow issues in LabVIEW.

Save variant configuration data with BAPI or FM

Hi experts,
I created a PP production order by using a configured material.
I can see internal object number in table AFPO-CUOBJ.
I'd like to change and save a value of characteristics by using ABAP.
Could you tell me it if there is a BAPI or FM to save values of characteristics in variant configuraion?
BR,

you can chnage the variant configuration data using below bapi with strcture    order_cfgs_value      =

in date Low field...value will be harcoded as '01.01.2011' and S_Date-high date field should be current date - 1.
I dnt want to go for code in report to handle this.
I tried with many option but could not able to see up the dates like as above.
Kindly help.

Variant to data boolean

Hello everybody,
I want to convert a variant data into boolean. I use the Variant to Data control, but in order to extract the boolean data, I assume, I need to provide it with the type of the data I want this conversion to be performed (boolean, that is). There 's a terminal to do so, but I don;t know whether I should use a constant (what's the numerical constant for the boolean type) or what sort of boolean constant I should link the terminal with? Shortly, I don't know what I should link it with.
THere's an enclosed picture coming with the post.
Thank you,

Database Variant to data not working when converted from LV 2010 to 9

Hi all,
I have a simple code which i made in LV 2010 for displaying data from an MS access sheet into an array in which i used the DATABASE VARIANT TO DATA tool. But when i converted this file into an LV 9 VI and opened it in another computer running with LV 9 , the wires connecting the data terminal of SELECT DATA tool and DATABASE VARIANT TO DATA tool are broken. Error message is Type 1 is 2d array and type 2 is void. Opening the same converted file in LV 2010 doesn't give any error and is running fine.Can anyone please tell me what should i do to rectify this problem.
Regards,
Nitzz.
Solved!

Custom ATP Check using Variant Configuration Data in sales order

I have a requirement to modify the standard SAP ATP check by including the variant configuration data entered on a item. Standard SAP does not use/include the characteristics data when doing the ATP. None of the available user exits would allow me to do this.
The scenario is the client has a configurable product that exist in inventory as one item, base unit as IN2. The batches that exist in inventory have the characteristics of width and length. The order data specifies a width and a length, they need the ATP to identify the availability based on the characteristics of the batch.
The solution was to present the user with a list of batches based on the characteristics that meet the criteria. The user would then have the option of choosing one of the batches which would mean that the line item would include the batch #. If the user does not want any of the batches, they could choose to select a Make to Order option, which would change the item category of the item, so that it creates a production order upon saving the order.
The problem I am having implementing this solution is I have not been able to identify the internal table(s) that contains the characteristics data in SAPMV45A after the configuration screen is called. If anyone knows where that information is during the sales order processing, it would be greatly appreciated.

Hello Jean,
Have you managed to find a solution as yet? I know you have not received any replies but am hoping you were able to resolve the problem as we are facing the exact issue on our project.
Please let me know,
Thanks,
