How to create multiple function for each value

Hi, I'm new to LabVIEW.
I need some help. Attached is my LabVIEW file.
I want to change the Formula VI for the 'Air Velocity vs Time' waveform to another formula (or multiple formula (can I use MathNode Script for this?)) to let it handle multiple values from the data and then display the result on the waveform graph. Or how can I do this?
Another one is how to change the scale for the 'Measurement Flow' from sensor to pressure? Using pressure sensor 0V-10V to -500Pa-500Pa.
Thanks in advance.

You could simply use a case structure around the Formula Express VI. When you say MathNode Script I'm assuming you're referring to MathScript? Or are you referring to the Formula Node. With either one you'd need to convert from dynamic data to arrays. With MathScrip you need to be aware that starting with LabVIEW 2009 MathScript requires a separate license.

You can create a custom scale for your measurement. You can do this in the DAQ Assistant.

How to print multiple footers for each page in RTF template xml report.

Hi,
How to print multiple footers for each page in RTF template xml report.
i am able to print ( two sets ) ...
up to last page ( one template ) and for last page ( another template).
i want to change the footer information based on the group value printed in the report ( it might be 5 to 6) In every report run.. can you please check and let me know do we have any feasibility to achieve this.
Thanks in advance.
Regards,
KAP.

You can remove all other logic, like last page only contents (start@last-page:body), etc and section breaks if any you have inserted manually.
Just have for-each@section logic.
It would be difficult for me to guess what you have done without looking at your RTF or describing here.

How to create a PR for each Maintenance Order

Dear All,
Please guide me how to create a PR for each Maintenance Order.
I test on Ides, I have some Maintenance Orders, all of them require the same stock material. When I run MRP, system always create one PR for all requirements. I don't know how to change.
Regards,
QuangDD

Hi,
As you planning for Stock Items, by running MRP, system will create single PR only. If it is non stock items, then it would be possible to create different PR based on Orders.

How to create xsd's for each table in repository instead of entire repos

Hi Gurus,
Is there any way i could create xsd's for each table in the repository separately instead of creating single xsd file from "Export repository schema" option which creates a single xml file for the entire repository.I need to create xsd for each table in repository...
Any Help greatly appreciated
Thanks
Aravind

Open the Lookup table you want the XSD for, in Data manger
Export it to access.( You can select all the fields you want to export to access and then check option "open Access after export")
Now in Access, again right click the table and export it to XML.
Provided you have .NET frame work installed on the machine where you are doing this export, you can do the following:
Use XSD.exe from command prompt and get the XSD.
Use the following link as a reference for XSD stuff.
http://msdn.microsoft.com/en-us/library/x6c1kb0s(VS.71).aspx
(OR)
Get the whole XML of the repository and distill the whole structure for Lookups and create XSD using any standard XML editor.

How to create diferents deliveries for each schedule line

Dear gurus,
I have sales orders with many schedule lines in order to deliver in diferents dates. We need to create all the deliveries together but each schedule line needs to be in a diferent delivery with the corresponding delivery date.
I analiced the customizing about pool for delivery creation (VL10) but all I can change is for display and can not change the way the delivery is created. If we select two schedule line with diferent dates, the proccess create only one delivery with the total quantity and the first date of delivery.
Anybody knows some way to make the proccess create individual deliveries from diferents schedule lines?
Tanks in advance!
Marina.

Hello Marina
I hope you are using VL10E. Did you try working with Delivery creation date (range) and Delivery Date calculation rule? For example if you go for a value of 2 for the CalcRuleDefltDlvCrDt ('Rule for determining default value for deliv. creation date), then system will consider only those sched lines which are to be delivered today and tomorrow.
You also have the possibility of setting up your own routine for CalcRuleDefltDlvCrDt.
Thirdly SAP has suggested a solution for Scheduling agreements ( valid for releases upto 4.7). In this SAP has suggested solution 4 for ensuring all schedule lines are not delivered together. You can customize the code to include Sales orders ( in stead of Sched Agreements) in your case. Though it is for release 4.7, I think you can use the smae concept in ECC also.

Check it out and let me know how it goes. Good luck.

How to create Multiple Address for a single customer

Respected Members,
In tcode Xd01 we create on customer but there we can maintain only one address but sometimes a scenario can be that single customer can have different address .
How to do that.Any exit is available to create multiple address with creation of single customer.
This provision is given while creating a Business Partner.Tcode is BP .In this Address Overview tab is there and you maintain multiple address to single Busines partner.
Same thing can we do for the customer.
Any solutions or suggestions,please give me your support.
Thanks

Hello Manish,
Unfortunately Customers have only one address. However you can use contact persons to store different addresses, or (in the Sales view) you can assign other partner functions with different addresses (e.g. one customer acting as the Sold-to partner may have different Ship-to partners).
If these options do not meet your requirements, you could extend the customer master data with your own functionality and enhance transaction XD01 with your own screens for holding alternate addresses.

John.

How To create Library Functions for Validate Items

Hi all,
My form Consists data block blk_user with two items
username and password
Both user name and Password are required Fields.
When user left these items Empty To show Alert
I Created Below Procedure and Called in Form_Level ON-ERROR Trigger.
PROCEDURE pcd_io_alert IS
     itm_name VARCHAR2(20);
BEGIN
     IF Error_type ='FRM' AND Error_code = 40202 THEN
     Message(get_item_property(NAME_IN('SYSTEM.CURSOR_item'), PROMPT_TEXT )||' Should
Not Be Empty');
     SET_ALERT_PROPERTY('ALT_IO',ALERT_MESSAGE_TEXT,
          (get_item_property(NAME_IN('SYSTEM.CURSOR_item'), PROMPT_TEXT ))||' Should Not
Be Empty');
     itm_name := Show_alert('ALT_IO');
RAISE FORM_TRIGGER_FAILURE;
     END IF;
END;
It working fine.
Could You Tell how to call or create this procedure as Library functions and call the created library in form To SHow Alert. Actually I want to create library functions to Validate and Show Alert Mesages.
Regards
R.MaheshBabu.

Hello,
Could you give Some examples or links related to how To create and call library functions For validate Items..For creation you already created one procedure and you called on error. So for creation and call it is clear. Now you are talking about validation for items. It depends on your requirement. As you check validation in items's triggers you can also check validation in function/procedure of library. You can use parameter to pass values and check the validations. And you can create the procedure/function in library like this...
PROCEDURE My_Proc(Parameter_Name IN DATATYPE) IS
Variables Declarations...
BEGIN
-- Here check the validation on the passed value.
EXCEPTION
-- Exception Handling part...
END;
FUNCTION My_Proc(Parameter_Name IN DATATYPE) RETURN DATATYPE IS
Variables Declarations...
BEGIN
-- Here check the validation on the passed value.
RETURN <ANY VALUE>;
EXCEPTION
-- Exception Handling part...
END;
Is it Possible to use system variable ':system.cursor_value' while creating PL/sql library functions?Yes, because it is clear as you used for CURRENT_ITEM like NAME_IN('SYSTEM.CURSOR_item') so you can use SYSTEM VARIABLES.

How to use multiple classes for each form

Hi,
I have created two forms using screen painter and now i want to use different classes for these two forms .
I have declared the Sbo Connection in main class i.e. Set Application ,Connection Context() but while connecting to other classes
for executing the code for that form SAP is not connected to that class.How to use multiple classes functionality i don't able to
do that.Please provide some sample codes for that as it will be more helpful for me to understand.
Thanks & Regards,
Amit

Hi Amit,
In fact, its more advisable to use separate classes for every form that you use. Have one common class, say, for eg., clsMain.cs which has all the connection and connectivity to other classes, wherein, the menu event and item event of this main class, will just be calling the menu / item event of other classes.
The individual functionality of the child classes will be called from the item / menu event of the respective classes.
Item event in clsMain.cs will be as below.
private void oApplication_ItemEvent(string FormUID, ref SAPbouiCOM.ItemEvent pVal, out bool BubbleEvent)
            SAPbouiCOM.Form oForm;
            BubbleEvent = true;
            try
                if ((pVal.FormTypeEx == "My_Form1Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm1_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
                if ((pVal.FormTypeEx == "My_Form2Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm2_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
Now, in the individual classes, you can have their respective item events, which will be called from the main class, and the respective functionalities will occur.
Hope this helps.
Regards,
Satish.

How to create a trigger for particular value insertion?

How to create Support function for internal Class use

I have created a class to find the MoonRise and Set time. There is a java code available and I am translating it to Obj-C.
My problem is that for the calculation there are many support functions which is internally used. When I try to duplicate this as follows
-(double) frac:(double)x {
// returns the fractional part of x as used in minimoon and minisun
double a;
a = x - floor(x);
if (a < 0) a += 1;
return a;
-(void)minimoon:(double)t {
// takes t and returns the geocentric ra and dec in an array mooneq
// claimed good to 5' (angle) in ra and 1' in dec
// tallies with another approximate method and with ICE for a couple of dates
double L0, L, LS, F, D, H, S, N, DL, CB, L_moon, B_moon, V, W, X, Y, Z, RHO;
//var mooneq = new Array;
L0 = frac(0.606433 + 1336.855225 * t); // mean longitude of moon
At this point it gives an error implicit declaration of function frac,
My question is how to create such helper functions which are used internally, actually there are many such functions where functionA call B which calls C.
Thanks
Raj

Here's yet another approach (creating a private category):
@interface MYClass (Private)
- (double)frac:(double)x;
@end
@implementation MYClass
- (void)minimoon:(double)t {
// takes t and returns the geocentric ra and dec in an array mooneq
// claimed good to 5' (angle) in ra and 1' in dec
// tallies with another approximate method and with ICE for a couple of dates
double L0, L, LS, F, D, H, S, N, DL, CB, L_moon, B_moon, V, W, X, Y, Z, RHO;
//var mooneq = new Array;
L0 = [self frac:(0.606433 + 1336.855225 * t)]; // mean longitude of moon
- (double)frac:(double)x
// returns the fractional part of x as used in minimoon and minisun
double a;
a = x - floor(x);
if (a < 0) a += 1;
return a;
@end

I liked the first method as I don't have to change much of the java code.
I like it too. I use that very regularly (though I often use C++/Objective C++), since there is typically a lot of implementation in any class that does not need to be an ObjC instance method. This approach helps to reduce the object's interface to its essentials while keeping maintenance low.
I'll put all the helper functions above the implementation.
Is there a good book/web site where I can get such insight? I know C and Delphi/pascal
Well, Objective-C is a superset of C. If you're porting Java, you'll find protocols (ObjC) similar to interfaces (Java).
*Getting Started*
Apple's version of ObjC is different from others. For the language, Apple's docs are the standard (IMO):
Language:
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/ObjC.pdf
If you are comfortable with C, this guide will help learning Objective-C quickly, though it has not been updated for (Apple's) Objective-C 2.0:

There are a few books on the ObjC2 language, but I have not read them (I just read Apple's docs for this).

Two related tasklists (Main/sub) with a workflow creating multiple subtasks for each maintask

Hey folks!
I'm really a SP-freshmen and i need a no-code solution (the farm doesn't really allow custom-code).
So this is what I've got:
A list called "ManagementDB" based on two columns, Work-teams (like HR/Sales) and the current head-manager of the specific work-team.
- IT will most likely manage this list while others may just read it.
A task list called Sub-tasks which will contain each subtask for the main ones.
- A Manager will finnish this task.
Another task list called Main-tasks, which (obviously) will be occupied by main-tasked referenced to subtasks.
- A Boss will be creating these tasks.
A Boss will go in to the Main-task list and create a new Task, for example "Check your employees vacationplans". As the Boss creates the main-task he will choose what teams that should do the task(like Sales/HR, remember this
is within a lookup from the "ManagementDB" list). Then there's separate task created in the sub-tasklist for each team chosen in the maintask creation.
As looping isn't possible within a SPD Workflow and as the lookup column containing all the choices is only a string in the workflow(Seperated with ";", like this: "HR; SALES; FINANCE") I'm really not seeing a good way of doing
this.
There are 80 different work-teams with managers and the best solution would be if the workflow were "flexible" rather then static (which is so far the only way I've managed to do this).
Kr,
Lankus

Without code, we're limited in our options in SP2010. If you move to SP2013, we can use loops and this is (fairly) easy to accomplish. Without it, the best option would probably be to do InfoPath. You could create a repeating table within a task that shows
the subtasks.

How to create multiple nodes for a feature in PE03

Hi Specialists,
I have a requirement for australia where we need to maintain multiple nodes in a feature ( Tcode : PE03).
Action Type      Action Reason
L6                      00
                          01
L7                      06
                          08
L2                      01
Issue is : 1) How can we maintian the above values in a feature tree.
                2) The SAP standard structure is using PME14 but PME14 does not contain the 2 above mentioned
                     fields i.e.( Action Type & Action Reason). Istead it is contained in structure PME04 .
                    SO how can we modify the SAP standard structure.
                3) The above strucure PME14 is being read in an SAP standard report RPCPSPQ0 :
                     i.e Payment Summary Report tcode: PC00_M13_PSGEN . If we want to accomodate the new requirement for        australia does that mean we need to modify SAP standard report / or is there a user exit/BADI available to avoid making changes to SAP standard report.
Please suggest.

Can you please supply the name of the Feature you are trying to use? it will help to understand the full picture.
