Dynamically change JCO parameters

Hi guys,
There is something extremely far-fetched I want to try. Using Web Dynpro, before making the RFC call, can i change/override some connection parameters of the JCO being used from the SLD.
Any radical ideas???

Hi Nirav,
Check out this link. I guess this might be helpful to you.

Dynamically changing Init Parameters

Hi,
We are going to upgrade our database from 10.1.0.5 to 10.2.0.5.
The database is running on pfile.
SQL> show parameter pfile
NAME TYPE VALUE
spfile string
After running the preupgrade tool, got the below warnings.
Update Parameters: [Update Oracle Database 10.2 init.ora or spfile]
WARNING: --> "streams_pool_size" needs to be increased to at least 50331648
WARNING: --> "session_max_open_files" needs to be increased to at least 20
I dont find these parameters in the pfile. Is it possible to alter these parameters dynamically?
Can i add these parameters to the pfile before upgrading the database?
SQL> show parameter streams
NAME TYPE VALUE
streams_pool_size big integer 0
SQL> show parameter session_max_open_files
NAME TYPE VALUE
session_max_open_files integer 10
Thanks,

As noted, if values are not explicitly set, they assume default values - see the documentation

How to dynamically change the text of a TextObject with embedded DataField?

Hi
I'm trying to dynamically change the text of a TextObject at runtime, by using the .NET library. My problem is that if one or more DatabaseFieldDefinition is embedded inside my text, I'm unable to change the "static text" only, by keeping the field, e.g. I have :
Text1 => "Contact Name: {Contact.Name}"
and I'd like to change it to anything else like:
Text1 => "Nom du Contact: {Contact.Name}"
Half of my TextObject is static text while second part comes from the dataset.
(of course the translation is dynamic - it is called at run-time and the new value to be set depends on the calling application language)
If I simply modify the Text property of my TextObject, the {Contact.Name} embedded field is not evaluated anymore by the Crystal Engine, but considered as a single text.
Using formulas or parameters looks quite difficult, because it means having many ones just for translation needs - I cannot control the way my users will create their reports and "force them" to use complex methods just in order to put a text and a value together...
Anyone knows how to deal with that ?

Only way I can think of doing this:
1) Create a formula (call it lang) and enter the string "Contact Name" in it
2) Place the {Contact.Name} field next to the string
3) So now you have:
ContactName: {Contact.Name}
4) Check what localization you are after. If you need "Nom du Contact", change the lang formula so it shows "Nom du Contact" using the code below:
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Public Class Form1
Inherits System.Windows.Forms.Form
Dim Report As New CrystalReport1()
Dim FormulaFields As FormulaFieldDefinitions
Dim FormulaField As FormulaFieldDefinition
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
FormulaFields = Report.DataDefinition.FormulaFields
FormulaField = FormulaFields.Item(0)
FormulaField.Text = "[formula text]"
CrystalReportViewer1.ReportSource = Report
End Sub
I realize this may not give you consistent spacing as the translations may have strings of differnt length. Perhaps someone has other idea(s)...

Dynamically changing the name of the .dll file to load in call Library

Our current model is to use dll files as "plug-in" modules for instruments and a top layer test step calls the appropriate driver dll.
For instance
the TestStep is called with the kenmore.dll passed as a parameter so the kenmore.dll file is loaded, the functions are registered and the functions are called. Next the TestStep is called with whirlpool.dll as a parameter now the whirlpool.dll is loaded the functions are registered and the functions are called. This works very well in our current CVI/LabWindows environment. Now we plan to work with LabView, we wish to retain this model (as DLL files, there are advantages in our model for us). We have not found a way to load these dll files from LabView without hard coding the path and filenames in.
Any suggestions on how to dynamically change the path in the Call Library module, or another suggested method of loading the dll via LabView?
Thanks,

As Ben has pointed out LabVIEW
scripting may be a possibility but you are going with that in highly
unsupported area. Also I happen to know that changing the library name
of a Call Library Node through scripting has produced unsupported
feature errors previous to LabVIEW 7.1 eventhough the method was there.
And LabVIEW 8 hides the whole scripting business behind the license
manager.
Another approach at least if the different DLLs do not change to often
thier functions and parameters would be to create a wrapper DLL. Have
it a method that loads the desired DLL and links its functions to
internal function pointers. Then when calling the actual function entry
points just redirect directly to the correct fucntion through that
function pointer. Since you are already working in CVI creating such a
DLL should be only a matter of taking out a little bit of your already
existing code and put it into a DLL project.

Dynamic XSLT processing - parameters?

Goal: I want my XSLT mapping to be dynamic, because I expect a certain number of fields with values in my XML, but these field names may change over time, so I have to make it dynamic.
Step 1: I made my output dynamic by using dynamic internal tables (field-symbols). So that I can change my internal tables easily with a custom-table. Done!
Step 2: My XSLT transformation should be handled dynamically. Not done!
Is this step 2 even possible?
I was thinking of passing PARAMETERS to my CALL TRANSFORMATION statement so that I can let know what fieldnames my XSLT can expect, but then the question remains if the ZTEST transformation can read this out for my purpose.
CALL TRANSFORMATION ztest
PARAMETERS (gt_param)
SOURCE XML gt_itab
RESULT (gt_result_xml).
...knowing that gt_param can only by of type
ABAP_TRANS_PARMBIND_TAB (for specifying strings) or
ABAP_TRANS_OBJBIND_TAB (for specifying object references) or
ABAP_TRANS_PARM_OBJ_BIND_TAB (for specifying data references).
Thus, is it possible to make my TRANSFORMATION handling dynamic (by using PARAMETERS or something else)? If yes, does anybody know how. Examples are appreciated.
Mehmet Metin

This can be done with basic XSLT. Use the XPath expression '*' to apply a template to each child of a given node (for example, if a node represents an ABAP structure, its children represent its components). In the template, use the XPath-function 'local-name()' to retrieve the name of the current element without namespace. Now you should have everything you need for creating the result tree.
For a working example in our XI system, see the following template:
<xsl:template match="ZMEDI_MELDUNG_DET">
<xsl:element name="{SEGID_N}">
    <xsl:element name='SEGID_N'>
      <xsl:value-of select="*[position()=1]"/>
    </xsl:element>
    <xsl:for-each select="*[position()>1 and text() != '']">
      <xsl:element name="{local-name()}">
        <xsl:value-of select="."/>
      </xsl:element>
    </xsl:for-each>
</xsl:element>
</xsl:template>
Here, I copy the components of the ABAP source structure ZMEDI_MELDUNG_DET (the structure name was fixed in my case, but it's easy to identify it without specifying its name, if it should be given at runtime only) into a result tree fragment with parent node name = the content of the ABAP component SEGID_N, the first child having the fixed name SEGID_N with (redundant) its value again, and after that all the components of the source structure, whatever they may be, if their content is non-empty (this was a format required by another non-SAP-development team).

Change step parameters in teststand edit mode

Hello,
I would like to know if it's possible to change the parameters in a step in edit mode of teststand.
I have attached a sequence with one step, in this step I want to select DMMx.
After the selection I want to teststand to fill in the parameters in the step so I can the choose which type of measurement and such.
If this is not possible how could I make something like this possible.
As you may see this will be a HAL, and the only option I can see which would do this is bij a string array but I don't want to type in the commands in string.

Hi Darkxceed
My recommendation for doing a HAL i TestStand would be to use an object oriented approach.
Create a class hirachy of your instruments like the following inside of LabVIEW:
Then use Dynamic Dispatch to make TestStand choose the instrument of interest. There is an example of using Dynamic Dispatching in TestStand here:
TestStand Using LabVIEW OOP Truck Example
https://decibel.ni.com/content/docs/DOC-24098
This solution will offcourse require you to read up on creating applications using object oriented programming in LabVIEW. We at NI have a course that walks you through both the theory and practical implementation. It is called Object Oriented Programming in LabVIEW. If you have a SSP agreement, you should be able to find it as Self Paced Online Training as a part of your contract.
There is also a good introduction to OOP in LabVIEW and HAL here:

How To dynamically change values in custom form

Hi,
Requirement is to change values in custom form dynamically that are passed by Global variables through standard form .
I have used forms personalization to call custom form and passing some parameters to custom form using global variables.
Now i have to change values displayed in custom form(already opened) when user moves from one record to another record.
I cannot change the standard form.Only i have write logic in custom form that dynamically changes values as user moves from one record to another in standard form.
Global variables values will be different for each record.
Pls let me know how i can achieve this.

Your question should be posted to the Enterprise Business Suite (EBS) forum. This forum is dedicated to non-EBS forms development.

Changing input parameters at GP-Runtime (Web Dynpro)

Hi,
I'm searching for a solution to change the input paramters for an action (at GP-Runtime) in a web dynpro application.
Is it possible to do something?
I cannot found something in the API, which solves the probelem.
Thanks for your helping hands
Steve

How many variations of the input parameters do you have. Could you give more details on the use case? Did you try the GP public API? It is capable of dynamically changing the input parameters.
Are you using the webdynpro GP-Interface?
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59
If you have a limited number of use cases, then you could create a Block type "Alternatives" and then create a WebDynpro callable object for each permutation of the input parameters.

Austin.

Can you dynamically change an LOV on the parameter form based on other params?

Can you dynamically change an LOV on the parameter form based on other parameters? For example, based on a entered purchase order number, create an LOV of the purchase order lines that belong to the entered PO #.

Hi
Accouding to my knoledge you can't do it.
If you want to build lov for that particular
value, you can do it in Forms.

Dynamically changing the report path

Is there any way to dynamically change the path where the reports are saved. Teststand 4.1.1
Message Edited by glennjammin on 04-21-2010 03:30 PM

L-3 Communications
Solved!
Go to Solution.

Yes you can run a VI in the ReportOptions Sequence, add it to the Setup of that sequence. If you dont use FileGlobals.Dated anywhere else then use a Local instead. Just remeber FileGlobals are only global to sequences that are contained in a SequenceFile. They are not global across SequenceFile unless you are using the Batch Process Model.
You will probably have to set a number of other parameters up to work with ReportOptions.Directory. The best way to handle this is to setup up you exact conditions statically (ie via the Config | Report Options... menu ). Place a breakpoint in the ReportOptions (use a label if you dont have any steps in the ReportOptions sequence at the moment) and run your Sequence. Remeber to use Test UUTs or Single Pass. You dont have to use your full test sequence just create a simple one step sequence.
When you reach the break point, then you can browse the Parameters.ReportOptions and see what properties are required to ensure your reports are setup correctly.
Hope this helps.

Dynamically changing Layout Managers Constraints

Hi,
Does any one worked on Changing the layout Constraints dynamically before ?, If so Can you explain me your experience and how it can be possible ?
Thanks,
Chekks

There are several ways of doing this, it really depends on your requirements as to which is suitable. (There are probably other ways of doing this as well).
- Try Reports XML Customizations
This is available in 6i and allows you to create a report dynamically on the fly. The template used will also allow you to change the paper size as well. The main limitation is that you are relying only on Reports defaulting to create the layout for you. The advantage is that you can store all your information to create the report in meta-data which can be driven by another tool.
- Use lexical parameters for queries and format triggers
Here, you have a fixed layout but dynamically change the query columns to the correct order. You would normally standardise on a "character" column type in order to do this. Even though the layout is fixed, you can use variable sized fields to push objects around. This can be difficult to setup.
- Use several layouts
You're reducing the options for the user, but you can have several layouts in the same report and turn them on/off. Effectively creating differing views of the same data.

Dynamically change icon name of push button

Hi,
I would like to ask how to dynamically change the icon name attribute of a push button in dialog programming. What is the syntax for assigning an icon name during runtime?
I am currently doing a multiple selection function for KNA1-KUNNR.
Initially, the icon name is ICON_ENTER_MORE. When the user picks up more than one customer, it should automatically change to ICON_DISPLAY_MORE. How can I do this?
here's the code i currently have:
DESCRIBE TABLE kunnr_ran LINES l_kunnr.
IF l_kunnr > 1.
      g_add_multiple = 'X'.
BT_MULT_CUST-icon_name = 'ICON_DISPLAY_MORE'.
ELSEIF l_kunnr = 1.
     CLEAR g_add_multiple.
BT_MULT_CUST-icon_name = 'ICON_ENTER_MORE'.
ENDIF.
The name of my pushbutton is BT_MULT_CUST.
The code in ** is not correct. I don't know the syntax in SAP. But that is how it is done in VB for example.
Thank you.
che =)

If you have not found your answer already, please try the following:
1) In screen layout painter: for the pushbutton in question (i.e. pb_multi_select), mark the "Output field" on the program attributes tab in the attributes window for the pushbutton. Make sure that its visible length is at least 2 too. This will "gray out" the "Text" and other fields.
2) In the TOP INCLUDE of the module program: add a variable for the pushbutton that is of type "icons-text" and don't forget to include <icons>. Below is an example
INCLUDE <icon>
DATA: pb_multi_select TYPE icons-text.
3) In a module called in the PBO modules for the screen that needs its button changed, call the function "ICON_CREATE" and pass at minimum the name of the icon and the field that you specified in step 2. Below is an example using the icon "ICON_DISPLAY_MORE", "ICON_ENTER_MORE", and a flag variable "MULTI_SEL_INFO_EXISTS" that indicates if any multiple selection information has already been entered. It would be set by the program (not automatically, but by coding) prior to the "IF" statement:
IF multi_sel_info_exists = 'X'.
CALL FUNCTION 'ICON_CREATE'
      EXPORTING
         name = 'ICON_DISPLAY_MORE'
      IMPORTING
         result = pb_multi_select.
ELSE.
CALL FUNCTION 'ICON_CREATE'
      EXPORTING
         name = 'ICON_ENTER_MORE'
      IMPORTING
         result = pb_multi_select.
ENDIF.
You can change the button as you see fit with multiple different calls inside of "IF" or "CASE" statements. Please see documentation for "ICON_CREATE" for other parameters.
Hope this helps,
Brian
