How to reference a field statically in a program?

Hi Everyone,
Can any one explain me how to reference a field statically.
As the error on Extended program check is as follows:
Field FLAG is not referenced statically in the program
where as the particular field has been defined as below in the program :
when 'SMTP_ADDR'.
DATA: flag type i.
I think is there a need to define the field globally.
Thanks and Regards,
Johny

Hi,
We can avoid this EPC check by deleting or putting a comment Or By passeing the EPC to it ie
DATA:
w_flag type i." #EPC
we can also avoid the EPC error by this way.then this willnt be aa part of EPC check
Thanks & Regards,

How to reference recording fields values?

hi,
i am in the LSMW Maintain field mapping and conversion rules screen and i used the following abap coding routine to move values to a destination field :-
g_amount = VA02-KURSK + 3.
write g_amount
   to VA02-KURSK decimals 2.
What i am doing above is i am adding a value of 3 to the destination structure field VA02-KURSK before writing it to the field. However when i run the convert data step of the lsmw it throws an abap run time error as "Unable to interpret "/ " as a number. " in the first line of the above code.
Can someone pls tell me how to fix this?

You've posted to the VB.Net forum which is for Windows Forms applications and service and general Visual Basic topics. Since this is LightSwitch it is outside of our bailiwick (the first error about the messagebox shouldn't appear in windows forms).
I'm going to move this to the LightSwitch forum were you should be able to get more appropriate help.

How to reference LONG field in trigger

I am trying to create a trigger (update and delete) for auditing purposes. The source table has a long field and I need to insert all columns (which includes the long field) into an audit table if any column in the source record changes or if the source record is deleted. I cannot reference :old.longfield or do a select into.
If anyone has a suggestion or has done it in the past, please email me at [email protected] or post an answer.
Thank You so much for your help !!!!!

As you have noticed, you cannot reference the value of a LONG column using :old/:new in a trigger. The work around is to instead process your audit information (including the LONG value) in an after statement trigger. Here is an example to get you started:

Script : how to change the Field name in standard program(ZM_MEDRUCK)

Hi Experts,
I am working with SAP SCRIPT. i need to change the Field Name that is PO NO to Document No & PO DATE to Document Date.
These are assigned in data declaration as gv_name and gv_date.
Can anyone help me to change this Fields.
Regards,
Vijayan.R

Hi,
You can archive this by making change in SAP script only. You don't need to touch the standard prgm.
Debug the script and find it out which fields (In script editor) are printing these text on layout... then just replace them by creating your own text...
You can create a text in TTDTG table,, like ZZPO_NAME = ( Document Name),, and use this filed in the script editor.
&ZZPO_NAME&

How to refernce the field in the cross-tab report

Hello,
I'm trying to refer to the field in the cross-tab report using GridRowColumnValue function.
The field name in formulas is DevelopmentTracking_SELECT.Completed, so I'm trying to refer like this:
GridRowColumnValue("DevelopmentTracking_SELECT.Completed")
I'm getting:
"This is not the name of a grid group for the field being formatted."
I've tried different way - gave the name of the field, for instance, or used the name form the Cross-tab expert - Max of DevelopmentTracking_SELECT.Completed, or simply use "Completed" - nothing worked.
I see the possible cause for it. DevelopmentTracking_SELECT.Completed is not a row or column name, in the Cross-tab expert this is a Summarized field. How to reference the field like this correctly?
Thank you,
Peter
Edited by: Peter Afonin on Feb 17, 2009 9:52 AM

Oh I thought it is
ROW: Product Name
COLUMN: Anticipated Date, Completed
SUMMARIZED FIELDS: Product Stage
Anyhow try to move the Completed field above the Anticipated Date in SUMMARIZED FIELDS by clicking up arrow.
Now right click on the field Completed go to format field-->write the suppress condition like this
WhilePrintingRecords;
boolenavar i;
i:=CurrentFieldValue;
false
Now right click on the Anticipated Date field and go to font and write the condition for color like this
WhilePrintingRecords;
boolenavar i;
If CurrentFieldValue >= CurrentDate Then
crGreen
Else If CurrentFieldValue < CurrentDate And i=False Then
crRed
Else
crBlack
I hope this helps!

How do I use a static reference to keep a VI in memory but then call it in parallel?

Hello all,
I have a MainVI and I want to call from it a SubVI in parallel so that I can have both windows open and responsive at the same time. The SubVI may be closed and reopened any number of times, but only one in existance at a time. I know how to do this using Open VI Reference, providing a relative path to my SubVI, checking its state to see if its already running, and if so bring the window to the front (using Front Panel: Open method with True/Standard inputs), and if not run it using the Invoke:Run method (and optionally opening its front panel programmatically). This method was working fine.
Now I have added functional global variables in my SubVI, and I want to keep them in memory inbetween opening the SubVI window. I can do this by putting a copy of the functional global in my MainVI, even though I don't use it there for anything. This works fine.
By accident, I have come across a reference to a Static VI Reference, which sounded like a vast improvement to my methodology, for the following reasons:
1) Keeps SubVI in memory all the time, eliminating the need to put the functional global in MainVI when it is not used there.
2) Tells LabVIEW to include SubVI when I build my executable, rather than me having to specifically mark it as Always Include in the build specification.
3) Eliminates the need to keep the path and SubVI name updated in a string constant in my code, in order to use the Open VI Reference.
However, trying to implement this solution, I have run into the problem that once you put a strictly-typed static VI reference (strict typing is required to keep it in memory) onto the block diagram, that VI is reserved for execution. That means I cannot run it using the Invoke:Run method. I haven't tried just putting it on the diagram directly as a subVI because I need it to run in parallel to the MainVI. I have searched through these forums extensively, and although there are several references to a static VI reference, none of them say explicitly how to actually run the darn thing! :-P
I very much appreciate any insight into my problem. If I have to go back to the old way it will work fine, but I really like the seeming elegance of this solution. I hope that it is technically feasible and I'm not misunderstanding something.
Thank you for your help,
-Joe

> If I understand you correctly, they can only really be used for re-entrant VIs.
No, a static VI reference can be used anywhere a regular VI reference (property nodes etc.) The reason for the hoop-jumping above is that we are really opening a reference to a CLONE (copy) of the VI identified by the static VI reference.
> Okay, I tried it, and got the code shown below... Any idea why it isn't working?
The VI you want to clone can't be on the diagram as a "normal" subVI. When you run your application you should be able to open that VI and see it just sitting there with a run arrow waiting to run. See attached example (LV2009SP1).
"share clones" vs "preallocate" has to do with whether you want each clone to preserve state (such as in an uninitialized shift register). Generally you use share clones. Occasionally it is useful to have multiple copies on a diagram that each remember some data, like "timestamp of last execution" in a shift register.
Other VIs in your spawned process don't have to be re-entrant unless they are functions that "wait forever". All the built-in G functions are re-entrant. It's pretty common to use a queue to feed data to a spawned process.
Spawning a process is more difficult than just running two parallel loops. It's useful because once you've made 1 copy, you can make 50. If you just want to do two things (vs n things) at once, I would just use two loops.

How can I share a static field between 2 class loaders?

Hi,
I've been googling for 2 days and it now seems I'm not understanding something because nobody seems to have my problem. Please, somebody tell me if I'm crazy.
The system's architecture:
I've got a web application running in a SunOne server. The app uses Struts for the MVC part and Spring to deal with business services and DAOs.
Beside the web app, beyond the application context, but in the same physical server, there are some processes, kind of batch processes that update tables and that kind of stuff, that run once a day. Theese processes are plain Java classes, with a main method, that are executed from ".sh" scripts with the "java" command.
What do I need to do?
"Simple". I need one of those Java processes to use one of the web app's service. This service has some DAOs injected by Spring. And the service itself is a bean defined in the Spring configuration file.
The solution is made-up of 2 parts:
1. I created a class, in the web app, with a static method that returns any bean defined in the Spring configuration file, or in other words, any bean in the application context. In my case, this method returns the service I need.
public class SpringApplicationContext implements ApplicationContextAware {
     private static ApplicationContext appContext;
     public void setApplicationContext(ApplicationContext context) throws BeansException {
          appContext = context;
     public static Object getBean(String nombreBean) {
          return appContext.getBean(nombreBean);
}The ApplicationContext is injected to the class by Spring through the setApplicationContext method. This is set in the Spring configuration file.
Well, this works fine if I call the getBean method from any class in the web app. But that's not what I need. I need to get a bean from outside the web app. From the "Java batch process".
2. Why doesn't it work from outside the web app? Because when I call getBean from the process outside the web app, a different class loader is executed to load the SpringApplicationContext class. Thus, the static field appContext is null. Am I right?
So, the question I need you to please answer me, the question I didn't find in Google:
How can I share the static field between the 2 class loaders?
If I can't, how can I load the SpringApplicationContext class, from the "Java batch process", with the same class loader my web app was started?
Or, do I need to load the SpringApplicationContext class again? Can't I use, from the process, the class already loaded by my web app?
I' sorry about my so extensive post...
Thank you very much!

zibilico wrote:
But maybe, if the web service stuff gets to complicated or it doesn't fulfill my needs, I'll set up a separate Spring context, that gets loaded everytime I run the "Java batch process". It'll have it's own Spring configuration files (these will be a fragment of the web app's config files), where I'll define only the beans I need to use, say the service and the 2 DAOs, and also the DB connection. Additionally, I'll set the classpath to use the beans classes of the web app. Thus, if the service and DAOs were modified in the app server, the process would load the modified classes in the following execution.You'll almost certainly have to do that even if you do use RMI, Web services etc. to connect.
What I suggest is that you split your web project into two source trees, the stuff that relates strictly to the web front end and the code which will be shared with the batch. The latter can then be treated as a library used by both the batch and web projects. That can include splitting Spring configuration files into common and specific, the common beans file can be retrieved from the classpath with an include. I regularly split web projects this way anyway, it helps impose decoupling between View/Controller and Model layers.
On the other hand, you might consider running these batch processes inside the web server on background threads.

HOW to include a reference currency fields in a view ?

Hello Experts,
<b>I am having Currency fields error in generic extraction</b>
I have table where I am trying to extract data to BW via generic extraction. When I tried
to extract with the TABLE its giving me an error
<b>Invalid extract structure template RPSCO of DataSource ZBW_REP3_TEST

Now I created a view with all the fields same as my table.
But its still giving me the same error and taking all the fields as a primary keys. I have over 12 currency fields in the table. I am confused how to fix this issue and add a currency field to my view?
hOW to include a reference currency fields in a view ?
All inputs are much appreciated.

How do I reference a field in form portlet?

I created a simple form portlet in Oracle Portal using the wizard.
I want to execute a custom pl/sql query using simple select statement. (e.g. select emp from scott where ...)
I created a new Button item.
In the PL/SQL Button Event Handler I put the select statement.
Now I have 2 questions.
Question 1. Do I have to use the Query or Custom button.
Question 2. In either way I get PLS-00428: an INTO clause is expected in this SELECT statement.
I guess the fundamental question here is how do I reference a field in the form?

If I understand you correctly you want to click on the button and then display a value selected from the database, right?
1. You have to use the Custom button - query is exclusive for the form query.
2. You will have to select the value into an interim PL/SQL variable and then set the form field using the portal session attribute.
The following principles apply:
* To set a field you have to use code like
p_session.set_value(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_RFS_ID',
p_value => 30);
p_session.save_session;
where
- p_session is available in most custom PL/SQL blocks - I'm not sure if its in the custom block for a button - this type of code is used mostly in the "cusom pl/sql before form is displayed" (last tab) - if its not available you might have to jump through some more hoops !:). It refers to a portal stored session that is used to store all the internal variables.
- block_name is either DEFAULT for simple forms or MASTER or DETAIL for master/detail forms
- p_attribute_name is the name of the field you want to set BUT (very important) prefixed with A_
- p_value is the actual value - here you will use your pl/sql variable.
so try something like:
l_number number;
select anumber into l_number from atable where ....;
p_session.set_value(
p_block_name => 'DEFAULT',
p_attribute_name => 'A_field1',
p_value => l_number);
p_session.save_session;

How does Reference Field work?

Hi All,
I have short of problem knowing how reference field works. I have one field in ABAP query: MBEW-STPRS. The field type is CURR and it have reference field T001-WAERS.
In query I made, the currency isn't occurs although I have set it to be display. I try to look how this reference field works in any source but can't find any answer. May be some of you can give me a little explanation.
Thank you so much
Regards
Hadi

Hi,
Reference fields work in the following way,
When you say quantity is 100, what it refers to - 100 pc, 100 bundles or 100 kg or 100 metres??? The unit of qty defines whether it is PC, KG, M etc...
In the database, SAP stores all amount values with 2 decimal places. But when SAP reads it, it interprets it based on the currency associated with the amount field.
We require reference fields to Currency/Quantity fields as they are meaningless with out having the units.
Ex: If we say, i paid 100. How can we figure out if he had paid 100 paise or 100 rupees.
So, units are must.
In case of quantity field QUAN, reference field will be always of type UNIT,
currency field CURR, reference field will be always of type CUKY.
It is mandatory to specify reference fields when we create fields of quantity/currency type in data base tables.
Hope this will clear you.
Thanks & Regards,
Pavan.

How do we reference a field that is contained in a sortingTable

Hi,
Do any of you smart people have an example of this solution.
Note: I have included the tag baseContext='variables' in the form.
How do we reference a field that is contained in a sortingTable.
If a sortingTable has selectEnabled set to true and the table has 5 rows and 3 columns. Suppose the checkbox on row 2 is checked. How does one reference the field defined at row 2/column 3 ?
Is this reference anywhere close ? variables[selected=true].rowSelected ?
And I am able to get first column values by refering sortingtable field name. I need first and second columns values. Please help me.
Thanks,
Sabaree.

How to: Reference fields XREF1/2 to be displayed in Acc Doc Line Item

Hi Experts,
May I know how to display the fields in the Line Item Level that can also be changed.
What I already did was the configuration OB32, OB41, FI>GL>Master Data>G/L Accts>Line Items>Define Special Fields for Line Item Dsiplay.
But it still not working. What is the proper way to configure these fields?
Thanks

In the Line item Display list in FBL*N follow this menu path: Settings
-> Special fields, and add the fields you want from relevant table.
The fields are later available for display, and you can choose them from
the Line item Display list following this menu: Settings -> Display
variant -> Current. From the hidden list you can now choose the fields
you want to have shown. If the technical name is shown for the fields,
the special fields are all starting with '1-U_'. It's important, that
you add the Special field, if the field also exist as Standard field.
The Special fields are shown in the bottom of the Hidden list.
Review the solution part of note 215798 the detailed steps.
XREF1 / XREF2 do not exist in the index table (BSIS/BSAS) for the G/L
account. Therefore you should create XREF1/2 as special field for
display via FAGLL03/FBL3N.
SPRO - ... - Define Special Fields for Line Item Display
There you should also include the field and store the change.
You do not have to run the RFPOSXEXT again, because the related
structure is generated automatically within the storage of the data.
After you have stored the 'new' field, you should run the report
BALVBUFDEL. This report will reset the ALV buffer, because the old
definition of the fieldcatalog does not have the needed fields, and
so it might happen that these are not displayed in the fieldlist of
the FAGLL03.
Please refer to the attached 984305 and 215798 Point 3.

How to access dynamic fields in a field symbol

hi
how do i access the dynamic fields created in side a field-symbol....
wht i mean is i have a table, whose workarea i assign to field symbol. but this table is runtime, altough i have debugged and found the values in this table, I want to accees the field symbol in a generic way.
say the table has 3 fields now fld1 fld2 and fld3 so i want to access the field symbol <fs> as <fs>-(name) where name can be anything fld1 or fld2 whichever i assign....
thanks. Let me know if you have any further questions.

Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to a field symbol before you can address it in a program.
Field symbols are similar to de-referenced pointers in the C programming language (that is, pointers to which the content operator * is applied). In ABAP, data references represent a real equivalent to pointers in the sense of variables that contain a memory address and can be used without the contents operator.
All operations programmed with field symbols are applied to the field assigned to it. A MOVE statement between two field symbols, for example, assigns the contents of the field assigned to another source field symbol to the field assigned to the target field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before the MOVEstatement.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks during the field assignment whether the assigned field matches the type of field symbol.
Field symbols provide greater flexibility when you address data objects:
·        You can assign one field symbol to another, which allows you to address subfields.
·        Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
·        You can also force a field symbol to take different technical properties than those of the field assigned to it (casting).
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. The MOVE statement (with your own auxiliary variables, if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.
To declare a field symbol, use the statement
FIELD-SYMBOLS .
For field symbols, the angle brackets are part of the syntax. They identify field symbols in the program code.
If you do not specify any additions, the field symbol.
in a static ASSIGN and:
ASSIGN (dobj) TO from the second loop pass onwards.

Child Node --> select * FROM TABLE( EUPS.FN_GET_CONTR_SAL_FOR_YEAR( employeId,startDate, endDate) ) based on selected parent node.
I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?
I will appreciate your help.

How to make a field mandatory in billing

How to make a field mandatory in billing document,if m right with the help of incomplition log but how.....
plz reply the full configuration.

Hi Mohan,
We normally create a billing document with reference any other document say Order or delivery.
so, all the necessary information in the invoice will be taken from preceeding doucments. Thats way in the order level we check for incompletion log. If any important data is missing in the order level then the succeding documents will not be created.
Thats way in the billing documents all the necessary information will come automatically either from preceeding documents or from master data.
Still you want to make any field mandatory, you can do these by modifieing Billing documents user exists,you can make which ever the fields are mandatory and to be checked before saving. so when you are going to save the invoice, it will check if these fields are maintained or not.
Hope this is clear.
Reward if helpful.
Thanks,
Praveen
