Calculated attribute: Concatenated String not possible ?

Hi,
whats the syntax to make a concatenated String view in a calculated attribute of an analytical view ?
For Example in metasyntax:
<CONST> = 'EDF'
CHANNEL_DESCRIPTION = 'Internet'
<CONST> || CHANNEL_DESCRIPTION = 'EDF Internet'
Is this possible ?
How ?
ThanXs
Martin

Hi,
You can use the "+" operator to concat two strings.This will call the CONCAT function of NewDB Engine to concatenate the strings.

How are calculable attributes influence on a performance

Hi WD Experts
I have recently faced with a small dilemma. Is it a good idea to use calculated attributes everywhere where it's possible? For example, I have a view with table. I can implement almost all logic in the view based on calculated attributes which will return values for icons, values for controls' visibility, values for textual labels in the table and so on.
How does the approach influence on a overall performance of my UI when user interacts with such controls? Here I suppose that each calculated attribute itself does not take any valuable time.
Thanx
Sergei

Roberto,
They are recalculated on every access. Whenever UI should be rendered, they are recalculated.
Some calculation are extremely cheap and do not impact performance:
1.
return element.getIsInProcessed() ? WDVisibility.VISIBLE : WDVisibility.BLANK;
2.
switch ( element.getSeverity() ) {
case -1: return WDTextViewSemanticColor.DIMINISHED;
case 0: return WDTextViewSemanticColor.POSITIVE;
case 1: return WDTextViewSemanticColor.CRITICAL;
case 2: return WDTextViewSemanticColor.NEGATIVE;
default: throw new IllegalArgumentException();
3.
final private static String[] STATE_ID2STATE_NAME = {"stopped", "starting", "running", "stopping"};
return STATE_ID2STATE_NAME[ element.getState() ];
On other hand, you have some large number of calculated attributes, that depends on the same condition, then it is better to create 1..1 non-singleton value sub-node, define all attributes here and populate them at once using supply function. Also you will not win a lot in terms of performance, the code will be far more maintanable while related calculations are not scattered across several methods.

Activity price calculation without activity not possible.

Hi,
I got the following error when I execute KSII ;
Activity price calculation without activity not possible.
Message no. KP230
Diagnosis
A program error occurred during activity price calculation. The SAP System could not determine the activity price for activity type 250902 in cost center 25093015 because only costs were entered, not activity quantities. The SAP System calculates the activity price by dividing the costs by the activity quantity.
System Response
The SAP System sets the activity price to zero.
Procedure
Inform your system administrator.
Please advice why the error occured?

Hi SAP Genes,
I am finding an error in One of our Product line "HPI India" where our Cost of Sales Accounting actual COGS cost is very less in comparison with the standard as in the past.as it is marked, as expected as we set it up in the begining of the Year we use Standard Cost we use Aug-July FY, only we are facing this error for this FY 11-12.
Please take a look at the COGS for HPI. which is marked in Blue all these cost are Highlited, The actual COGS cost is very less in comparison with the standard as in the past.
And for rest of the Product Line item is working fine,
Please suggest me the cause, i am attaching the Analysis sheet as well for your guidance.

Why i am not able to see calculated Attribute in Context

Hi all,
I am not able to see <b>calculated Attiribute</b> in Context...our NWDS version is 2.0.16..Could anyone tell me the reason...

Hi
if you have not created value attibute?
Create a value attribute by right clicking the context.Right click the newly created value attribute there you can see the calculated attribute property

Thanks Rama,
Acutally i accidentally commented the lo_nd_student = wd_context ....etc
this line was commented .
i have one small requirement to fetch data from local customised table and fill the same to internal table and bind that to table node.
my table node is student having attributes as name , city and number , all are of type strings.
now i created one custom table zstudent having ID - char of length 10,
name of type string
city of type string
num of type string
i have inserted records
but when i use select query to fill data from this zstudent to my internal table of type lt_student type wd_this->elements_student ,
im getting same above error.

Using Javascript to create concatenated string from checkbox fields to one text field

Hi. I have a PDF form that I am trying to have output to a spreadsheet that matches my database schema. Here is the dilemna:
* I have a set of checkboxes for available languages (LANGUAGE_ENGLISH, LANGUAGE_SPANISH, etc.) When they export to spreadsheet, the value is TRUE.
* I need to take values from checked boxes and create a single string in a text field called LANGUAGE_DISPLAY (so my UI will not need to do the concatenation). If LANGUAGE_ENGLISH is TRUE (checked), append "English, " to LANGUAGE_DISPLAY, else append "". Then, if LANGUAGE_SPANISH is TRUE (checked), append "Spanish, " to LANGUAGE_DISPLAY, else append "". And on and on
In the LANGUAGE_DISPLAY text field properties, I am inserting a Custom Calculation script to try to achieve this, but am not getting any results. I tried teh following even trying to pull the checkboxes default values and string them together:
box1 = this.getField("LANGUAGE_ENGLISH").value.toSrting();
box2 = this.getField("LANGUAGE_FARSI").value.toSrting();
box3 = this.getField("LANGUAGE_MANDARIN").value.toSrting();
event.value = box1 + ', ' + box2 + ', ' + box3;
I also played with this to get the desired strings output...but to no avail:
if ( LANGUAGE_ENGLISH.rawValue == true )
box1.rawValue = "English, ";
if ( LANGUAGE_FARSI.rawValue == true )
box1.rawValue = "Farsi, ";
if ( LANGUAGE_HEBREW.rawValue == true )
box1.rawValue = "Hebrew, ";
event.value = box1 + box2 + box3;
Then I tried to simplify to see one field output so used this script...still no results:
event.value = "";
var f = this.getField("LANGUAGE_ENGLISH");
if ( f.isBoxChecked() == true) {
event.value = "English";
Couple questions:
1) Am I on the right track with any of these scripts?
2) Is there something else I need to do to get the script to run before running the Create Spreadsheet with Data Files comman in Acrobat to get my csv file output? Maybe there needs to be some event to get the checkbox values read by that field in order to calculate/create the string.
Appreciate any help you can provide.

LiveCycle Designer has shipped with all Acrobat Professional versions since the "Professional" version was introduced with version 6.
You do not let us know want results you get in the field or the JavaScript console.
Using:
box1 = this.getField("LANGUAGE_ENGLISH").value.toString();
box2 = this.getField("LANGUAGE_FARSI").value.toString();
box3 = this.getField("LANGUAGE_MANDARIN").value.toString();
event.value = box1 + ', ' + box2 + ', ' + box3;
returns "Off, Off, Off", when no box is checked and returns "Yes" for the appropriate box being checked when the default value is used for the creation of the check box. So if one would make the 'Export Value' of the box from the default value of 'Yes" to the appropriate language, one would get a more desirable result. But for each unchecked box the value would appear as "Off". So one needs to change the 'Off' value to a null string. But one is still left with the separator when there is an unchecked option.
Using the following document level function:
// Concatenate 3 strings with separators where needed
function fillin(s1, s2, s3, sep) {
Purpose: concatenate up to 3 strings with an optional separator
inputs:
s1: required input string text or empty string
s2: required input string text or empty string
s3: required input string text or empty string
sep: optional separator sting
returns:
sResult concatenated string
// variable to determine how to concatenate the strings
var test = 0; // all strings null
var sResult; // re slut string to return
// force any number string to a character string for input variables
s1 = s1.toString();
s2 = s2.toString();
s3 = s3.toString();
if(sep.toString() == undefined) sep = ''; // if sep is undefined force to null
assign a binary value for each string present
so the computed value of the strings will indicate which strings are present
when converted to a binary value
if (s1 != "") test += 1; // string 1 present add binary value: 001
if (s2 != "") test += 2; // string 2 present add binary value: 010
if (s3 != "") test += 4; // string 3 present add binary value: 100
/* return appropriate string combination based on
calculated test value as a binary value
switch (test.toString(2)) {
case "0": // no non-empty strings passed - binary 0
sResult = "";
break;
case "1": // only string 1 present - binary 1
sResult = s1;
break;
case "10": // only string 2 present - binary 10
sResult = s2;
break;
case "11": // string 1 and 2 present - binary 10 + 1
sResult = s1 + sep + s2;
break;
case "100": // only string 3 present - binary 100
sResult = s3;
break;
case "101": // string 1 and 3 - binary 100 + 001
sResult = s1 + sep + s3;
break;
case "110": // string 2 and 3 - binary 100 + 010
sResult = s2 + sep + s3;
break;
case "111": // all 3 strings - binary 100 + 010 + 001
sResult = s1 + sep + s2 + sep + s3;
break;
default: // any missed combinations
sResult = "";
break;
return sResult;
And the following cleaned up custom calculation script:
box1 = this.getField("LANGUAGE_ENGLISH").value;
box2 = this.getField("LANGUAGE_FARSI").value;
box3 = this.getField("LANGUAGE_MANDARIN").value;
if (box1 == 'Off') box1 = '';
if (box2 == 'Off') box2 = '';
if (box3 == 'Off') box3 = '';
event.value = fillin(box1, box2, box3, ', ');
One will get the list of languages with the optional separator for 2 or more language selections.

Calculated attributes in WDA

Hi people,
I'm new in WebDynpro for Abap. Is it possible to declare a calculated attribute like in WebDynpro for Java? I can't find a attribute-property for doing that.
Is this concept not available in WDA?
Regards,
Thomas

Hi,
in WD4Java you have the possibility to declare an attribute as "calculated". The framework generates then 2 methodes, a getter and a setter method, which the application developer can use to put in his coding.
A use case can be the following: You have a Inputfield with a simple value help (i.e. from the domain of the data element). The value you can see, after the selection is the key (of the key-value list). Now I want to show near the inputfield the value of the selected key. In this case I can declare (in WD4Java) a calculated attribute which i bind to a TextView element near the Input field. The getter methode of the attribute (implemented by the application developer) determines the value of the selected key.
If this wasn't clear enough, visit this [link|http://help.sap.com/erp2005_ehp_03/helpdata/EN/7f/a0384162316532e10000000a1550b0/frameset.htm], where the concept of calculated attributes is described in detail.

SetAttribute at calculated attribute at prev next binding

I use JDev version 10.1.2.1.0 (Build 1913). I try to set attribute at calculated attribute.. that all row divide some page using prev next binding. The result was disorder. I think i must set attribute repeat every i click prev next button.. but i don't know where i must overwrite method form prev next binding.. or any other solution... please give me advice.. thank you

Dimitar, thank you for your response.
If I am trying to insert a new row (not update an existing one), I believe I need to create a Managed Property bomEditChild under the Managed Bean bomCRUD, and then set the binding of the af:InputText to +#{bomCRUD.bomEditChild}+ as seen below:
<af:popup id="p1" ... >
<af:dialog id="d2" dialogListener="#{DialogListenerCollection.editDialogListener}" title="BOM Edit">
<af:inputText label="Child" id="it1" binding="#{BomCRUD.bomEditChild}"/>
</af:popup>
From adfc-config.xml
<managed-bean id="__11">
<managed-bean-name id="__9">BomCRUD</managed-bean-name>
<managed-bean-class id="__12">erp.view.framework.BomCRUD</managed-bean-class>
<managed-bean-scope id="__10">request</managed-bean-scope>
<managed-property id="__2">
<property-name id="__3">bomEditChild</property-name>
<property-class>oracle.adf.view.rich.component.rich.input.RichInputText</property-class>
<value id="__1"></value>
</managed-property>
</managed-bean>
However, when I print the value of the String Child variable of the createChildren class, I get the following:
System.out.println("Child: " + Child); // output command gets me the text below
+Child: RichInputText[UIXEditableFacesBeanImpl, id=it1]+
The createChildren method is detailed below in the pages definition file and implemented in the AppModuleImpl class.
<methodAction id="createChildren" ...>
<NamedData NDName="Child" NDValue="#{BomCRUD.bomEditChild}" NDType="java.lang.String"/>
</methodAction>
It appears the value being passed into my createChildren class is the container ID, not the value entered into the container by the customer. The output is the same whether I declare bomEditChild as a Managed Property under the Managed Bean bomCRUD or not. I am still unsure how to grab the value of the inputted text and/or if the managed property is updating before the createChildren method is being called via the editDialogListener.
Any further ideas?

Calculated attribute?

Hi,
Wat is the actual use of this and also giv me some sample for this..when and wher we use it?
**Helpful answers will be appreciated...
GS

Hi
The values of context attributes are normally saved in node elements of a controller context at runtime, and with data binding are displayed in the UI using a generic formatting mechanism (for Dictionary-based types).
In many cases, saved context data should be transferred identically, instead it should be converted before the display. A typical example is displaying an address text based on name and gender. Using the two context attributes Name=Maier and Gender=male, the standardized address text 'Dear Mr. Maier! should be displayed in the user interface. This text can be saved by defining an additional value attribute Address in the controller context. In multiple context nodes, each individual node element would then have the additional context attribute called Address, where the name would be saved redundantly as part of the address.
Calculated context attributes are a more elegant way of handling the example. These are not saved specially in the context, they are calculated (read) where necessary by the controller instead. Where necessary can mean that UI elements should display the content of a calculated attribute, or that the value is accessed by the program in the controller coding. The calculation method is called automatically by the Web Dynpro runtime environment. A calculated context attribute is calculated in an automatically generated access method using signature
<CalcAttrType> get<NodeName><CalcAttrName>(<NodeName>Element element).
For a calculated context attribute called FullNameCalc of type String in node UserData in the context of the FormView view, this results in access method
java.lang.String getUserDataFullNameCalc(
IPrivateFormView.IUserDataElement element).
The calculation method is called automatically where necessary by the Web Dynpro runtime environment. It passes a reference to the node element to which the calculated context attribute refers. If this method were defined in a multiple node with cardinality 0..n, for example, then the access method would be called for each node element that is available in the node at runtime. In this way, the full name of a customer could be displayed in a third table column, consisting of first and last names. The access method would be called for each row (each node element) in the table.
It is expected that the access method for calculating a calculated context attribute is based on the same node elements other attributes.
Within the generated access method for a context attribute, the context attribute to be calculated should not be accessed, as this results in the access method being called recursively. A recursion termination occurs only if you implement a recursion condition.
According to the Web Dynpro naming convention, calculated context attributes should contain the ending Calc for Calculated in the name, such as SalutationCalc or TotalPriceCalc. This makes the application coding easier to read with respect to the components from the calculated context attributes.

UCCX 8 - DOC[variable] usage not possible ???

Hi all,
I'm actually busy developping some scripts and I'm able to upload prompts, documents, and everything standalone. Now I will need to compile everything in a script and ideally I would need to put some parameters as DOCument filename...
If I try with a Document like :
Name : myDocument
Type : Document
Value : DOC["FileStored.xml"]
It works perfectly.
If I try the following like :
Name : myVariable
Type : String
Value : "FileStored.xml"
Name : myDocument2
Type : Document
Value : DOC[myVariable]
It seems not to work.
My main goal is to be able to go and pick the right XML file depending of some conditions I might put in my script... If not possible it will need to put many "if" to determine which file I need instead of concatenating the right file name based on my conditions ...
Any tip on how to do this?
Thanks in advance
Regards
Christophe

Hi Christophe
My approach to this has been as follows:
String, parameter, sDocumentFilename
So sDocumentFilename is a simple String, and made a parameter enterable in the web UI. You would set this to "myfile.xml" or whatever is appropriate.
THen in the script:
set docWhatever = DOC[sDocumentFilename]
This correctly sets docWhatever to DOC[myfile.xml]
Presumably it's some hidden magic of the Document object/set step that makes it work like this rather than using the variable name of the string in the variable definition for the Document. If I understand what you are asking correctly :-)

Not possible to output CFTREEITEM in a CFC function?

Hi there,
I am parsing a sorted list of strings (in the form of a/b/c/,
a/b/c, /a/c/d etc.) and trying to make a treeview out of it.
I have the CFFORM and CFTREE tag in the top function and the
code that generate CFTREEITEM in a subfunction, but I got the
following error:
Context validation error for tag cftreeitem.
The tag must be nested inside a cftree tag.
It seems that ColdFusion doesn't recognize that calling code
is already nested inside a CFTREE tag in the top function. I
extract the code generating CFTREEITEMs to a sub function because
it is called multiple times from different context, it would be a
lot of hassle and quite stupid to "inline" it.
If what I am trying is, for whatever reason, not possible,
would it be possible then to have the sub function generate the
code into a string and somehow dynamically evaluate that?
Any hints or tips will be greatly appreciated!

SSFCOMPOSER - 154 - No output request open. End not possible.

Hi Experts,
I'm trying to print multiple smartforms using FMs SSF_OPEN and SSF_CLOSE. Inside the main program RBDAPP01 (Inbound processing for IDOCS) there is a loop at the IDOCS to be processed. Deep within the processing, we have a custom FM being called which prints smartforms. Since there is a loop at the calling main program, I have organized the code in the custom FM such that the first IDOC calls SSF_OPEN and the last IDOC calls SSF_CLOSE, so that all IDOCS in between will be able to print their smartforms. Here is the call stack:

The problem is:
1. When I only have 1 IDOC being processed, SSF_OPEN and SSF_CLOSE happens in the custom FM at the same time. This creates a successful spool.
2. Whereas, when I have 2 or more IDOCS, SSF_OPEN happens in the first IDOC, but then it goes back to the calling program, and then when the last IDOC is encountered SSF_CLOSE is called. The FM SSF_CLOSE in this scenario calls the exception INTERNAL_ERROR (sy-subrc = 2).
The system message is SSFCOMPOSER - 154 - No output request open. End not possible.
Why is this happening? Is it because that other programs (calling programs) may have affected the status of SSF_OPEN? It seems that the SSF_OPEN is no longer open.
Thanks in Advanced,
Jack

No, it will not hold the smartform open, but you don't need to hold it open in order for printout to be accumulated in one spool. Spool system does the accumulation automatically, provided the spool requests that are to be added to an existing spool request are:
- generated in the same transaction and
- have the same attributes (such as user, title, output device, client from which the request was issued, number of copies, priority, cover sheet setting, archive mode, and ABAP session number).
Important is: where do OUTPUT_OPTIONS like printer come from currently? Is print parameters popup displayed on first Idoc for user to choose printer and options? Or do you use USER_SETTINGS = 'X' to simply take over defaults from user master? If the print options dialog is displayed, it needs to be controlled as well so it's displayed only once.
Assuming print options come from the user in dialog, the logic without explicit open/close could look somewhat like this:
On first idoc:
- call SSF_OPEN importing JOB_OUTPUT_OPTIONS to display print options dialog; move-corresponding JOB_OUTPUT_OPTIONS to global OUTPUT_OPTIONS;
- set OUTPUT_OPTIONS-TDNEWID = 'X' and clear OUTPUT_OPTIONS-TDFINAL, to ensure new spool will be started (overriding user choices for these parameters!);
- if the user has set OUTPUT_OPTIONS-TDIMMED = 'X' save it globally and clear it;
- set CONTROL_PARAMETERS-NO_OPEN = 'X';
On subsequent idoc:
- clear OUTPUT_OPTIONS-TDNEWID;
- clear CONTROL_PARAMETERS-NO_OPEN;
On last idoc:
- set OUTPUT_OPTIONS-TDFINAL = 'X' (this is not absolutely necessary, but prevents further appending to the spool);
- restore OUTPUT_OPTIONS-TDIMMED from the value saved on first idoc;
Calling Smartform:
- set CONTROL_PARAMETERS-NO_DIALOG = 'X';
- call smartform passing OUTPUT_OPTIONS and CONTROL_PARAMETERS;
The logic is somewhat complicated; I'd wrap it in a class (singleton, which would be de-instantiated after last idoc) to avoid global data and code other than simple method call(s) in FM.
Even if you decide to refactor the logic, it would still be important to understand, I think, why the current logic does not work (where and why smartform gets closed)... Maybe there are some nasty "surprises" somewhere, and your current algorithm should work.

hi ,
The attribute M_HANDLER is an attirbute of component controller (as told by your post) and so you cannot access it as you have done it.
You will have to access it as .
WD_COMP_CONTROLLER->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD(I_ID = 'S_CARR_ID' ).
Try doing it.
Or else , if you have created a similar attribute in your view itself , then it is "INITIAL" and hence you are getting the dump.
You will have to assign the view attribute "M_HANDLER" with the value of your component controller attribute "M_HANDLER" ,because all the initializations are done in WDDOINIT of comp controller and on component controller atribute "M_HANDLER".
Thanks,
aditya.

BDC transaction "The function is not possible"

Dear Experts,
I have made a BDC transaction program according to recording from SHDB in order to have batch transaction for FB50.
However, when I run the program. It shows an error "The function is not possible". But when I press the "Save" button manually, the function passed and result is saved. Just do not know what happens.
report YFB50 no standard page heading line-size 255.
include bdcrecx1.
type-pools : TRUXS.
data : rawdata type TRUXS_T_TEXT_DATA.
parameters: sfile TYPE localfile default 'C:\fb50.txt'.

Now should work fine..
