Use of % sign in data declaration

can any one explain me the use and the purpose of using % sign in declaring data and subroutines and internal tables.what does % means?
eg.
DATA %count-lfa1(4) TYPE x.
DATA %linr-lfa1(2).
DATA: BEGIN OF %joinwa,
        lfa1 LIKE lfa1,
        adr6 LIKE adr6,
        adr3 LIKE adr3,
        adr2 LIKE adr2,
      END OF %joinwa.
PERFORM %download
Thanks

I don't belive there is anything special with the % being used in the name. It does look strange and is unusual but is just another character in the name.
Just checked the help and it discourages this practice:
<i>A type name can be up to 30 characters long. The name may only consist of alphanumeric characters and the underscore character. It may not consist entirely of digits. Special characters such as German umlauts are not allowed. As well as these characters, certain special characters are used internall. However, these should not be used in application programs. SPACE is a reserved name, and cannot therefore be used. Furthermore, you should not use a field in a statement if it has the same name as one of the additions of the keyword (for example: PERFORM SUB USING CHANGING.).
Recommendations for Type Names:
Always start the name with a letter.
Use the underscore to separate compound names (for example, NEW_PRODUCT. </i>

What is the use of # in data declaration

hi experts,
i am working in one of the old programs, where in data declaration they have used -
data: matnr like mara-matnr,##
mfrpn like mara-mfrpn,##
and when i work in front end editor (4.7c), these data come in red colour. i know when i comment any line with (*), that line comes in red colour.
i want to know why these lines comes in red colour.
is it any pseudo comment of older version or what.
plz rectify my doubt.
Thanks.
Sri.

Hi Sakthi,
means a character that cannot be displayed. Probably thes are control characters from you old system, e.g. linefeed, tab, carriage return or the like.
The lines are displayed in red because the editor does not know how to handle. So # is ignored. You can delete the characters to have a better look or you can do the same as the editor does: Ignore them. There is definitely to syntactcal meaning at all.

Many thanks

As a general rule, it's a good idea to separate the
presentation (JSP and HTML) from the business rules
(database access). I know you didn't do that on the
AS/400, you had display files and business logic in
the same program (at least, we certainly do in ours),
but it's a good policy to follow in the web world.
That means, don't put your database access code in
the JSP. Other than that, it depends on the data.
If you have simple data (e.g. customer's name and
d address) then a Java bean would suffice. If you
have complex data (e.g. customer's payment history)
then a bean still might suffice. You would use an
"include" if you had some data (static or dynamic)
that you wanted to appear in several different pages
in the same form.Thanks, I figured putting the code in the JSP was not the best way, but I wasn't sure about the other options.

Data declaration error in adobe form

hi,
i m just remake a smartform into adobeform.but while doing so it's giving me error regarding data declaration.
I had declare some of internal table as type of defiened type but at code initialzation it giving it's not a internal table.
global data
it_abc type ty_abc,
types :
types: begin of ty_abc,
           ab(8) type c,
           bc(4) type c,
          end of abc.
when i m creating a internal table in code initialization it's giving me that already declared.
code initialization.
data : it_abc type table of ty_abc.
Plz help me out.
Regards
Ricky

Hi Maheshwari,
After the declaration of the TYPES Structure, you need to declare the Internal Table. As follows
TYPES
types: begin of ty_abc,
          ab(8) type c,
          bc(4) type c,
          end of abc,
          tt_abc type standard table of ty_abc initial size 0.
And in Global Declaration you use the newly created Internal Table (which is created using the Types Statement). And in Code Initialization you can use the Global Declaration internal table.

Dynamic data declaration refering to local data defined in another program

Here is the situation:
The standard program SAPICP__ , SAPICF__ and several other of same series have a form routine REPOSITORY_DEVCLASS_ADD. this subroutine in all SAPI* programs has parameter REPOSITORY of type REPOSITORY (declared as internal table with header lines) and type REPOSITORY is declared with different component in each program.
Now the problem is that i need to call subroutine REPOSITORY_DEVCLASS_ADD dynamically from my program and so i want to dynamically declare the table REPOSITORY in my program to pass to this subroutine and as program is not yet loaded into memory i have no way to achieve this.
Can some one help in achieve this?

Hello Fred,
That's a big task, even if it looks "easy". My first idea is, your request can not be covered by dynamic programming. a) every node has a different structure (I guess), b) the code itself has to be adjusted to the nodes in use as well. I.e. when a dynamic data declaration would be possible, the coding has to adhere the used number of nodes.
My recommendation:
- declare as many standard tables (nodes) as possible
- the code for each node has to be implemented
- define the number of used nodes by a parameter or an interface
Have success,
Heinz

How to use Reference type of Data Element

Hi guys, is there anyone could give me a trace how to use reference type of data element.
More details i'm going to reach is:
I create 2 tables:
eq.
1. table ZFIRST has field X with data element ZFX (Data element i declared).
2. table ZSECOND has field Y.
Here at field Y (second table) I'm going to declare a new data element say it ZFY, but in ZFY I'm going to use the data element as i declared before (ZFX). Is it possible if I do it using reference type data element (SE11)?
I already did this way, but I got error :
Field Y: Reference ZFX to class w/o interface cannot be used in DB table ZSECOND
What does it mean?. Did I miss something about using reference data element type?.
This error occurs when I activate ZSECOND table. However in creating ZFY (reference) to data element ZFX, there is no error occur.
The point is I need to RE-declared existing data element and ot put existing data element(ZFX) to my current table (ZSECOND).
Any helpful will be highly appreciated.
Thanks.

Field Y: Reference ZFX to class w/o interface cannot be used in DB table ZSECOND
What does it mean?. Did I miss something about using reference data element type?.
Apparently system doesn't allow you to type a transparent table field with deep type. This refers to references and tables types as components. The RDBMS (Relational DB Management System) cannot interpret this componenets correclty and mapp them to TABLEs in DB.
So I am affraid you won't be able to type table component with reference to other data element.
The point is I need to RE-declared existing data element and ot put existing data element(ZFX) to my current table (ZSECOND).
Sorry but I don't get it, could you please explain this more clearly. Maybe then we can think of some workaround for you.

Help reqd - Data declaration

Hi,
I have a problem here. I am analyzing an existing program. This is an active prg in Production.
In that I see usage of an internal table called 'itab1'. On double clicking on it (to find it's data declaration) it takes no-where. It asks if I would like to create it.
In an include program (which in embedded in this main program), I find some declaration as follows:
data: itab&1 like &2 occurs 0 with header line.
Can you help me understand this? I need to change the data declaration for this 'itab1' for an upgrade.
Regards,
Sanju.

Macros are defined using the following statement:
DEFINE conversion.
if &1 is not initial.
&2 = c_X.
else.
&2 = space.
endif.
END-OF-DEFINITION.
You apply it like described bellow:
conversion var_1 var_return.
My guess is that this internal table is being declared using the macro parameter. so, if &1 is valued with "10", that internal table will be named itab10.
Not quite sure about that, but maybe that's what is happening. Try to find the place where the macro is being called and see if &1 value is '1'.

How to programmatically sign test data?

Hello LV fans,
I’m looking for some ideas/methods to programmatically apply a digital signature to my test data. Currently I write to Excel, using ActiveX, then print and manually sign each data sheet. I’m open to new ideas to improve this process.
thanks

Hello Jared,
I'm not digitally signing my test reports now. I have to print them out, sign them, then have them scanned in for a permanent record. My VI pulls up the users' log in ID from the computer, and puts the users' name on the report. I'd like to take the process one step further and have each report digitally signed. Perhaps using MS Excel's digitial signature, or I could have the reports saved as pdf's and use Adobe Acrobat 8.0.
thanks..

Dynamic data declaration

I posted same thread into "Dictionary section"
Hi,
I have a following issue - I am not sure whether this is possible - so I need your feedback/expertise.
I have a custom table (example ZABC) with several fields in it - one of them being TABNAME . Content of that table ZABC is
MANDT TABNAME FIELDNAME ZCHECK
800 KNA1                KUNNR
800 KNA1                NAME1         X
800 KNA1                NAME2         X
800 KNA1                KUNNR
800 KNVV                BZIRK           X
800 KNAS                KUNNR
800 KNAS                STCEG
etc.
There is no rule how many entries will be in this ZABC table - I guess it will be less than 20 - but this is not business rule. Also do not know how many different "tables" could be specified.
Fields MANDT and ZCHECK fields are not important at this stage.
The challenge I have is to fetch data for only those fields from their specified physical tables (KNA1, KNVV, KNAS) in internal tables.
In this case I would need to have 3 internal tables one for KNA1, one for KNAS and one for KNVV.
I need to keep those "internal" table with content throughout the entire program for certain validation.
I know that I should dynamically define those internal tables but I have issues not knowing how many tables will be defined in ZABC table and I personally do not want to declare "<fs_itab> TYPE ANY TABLE" 20 or so times as fs_itab1 - fs_itab20.
Is there any way I can dynamically create as many internal tables as needed and keep their content throughout program run-time.
Regards
Goran

All those examples you'all posted are great BUT it does not answer my question nor help me to solve my issue. Maybe I was not clear enough ... or something is wrong with me
Once again.
I have no problem to get a dynamically defined table and fill its content from ONE physicall table. That is pretty straight forward. The issue I have is that I do not know how many dynamically tables I will have to define and later asign to field symbol. Look at my custom table above and you will understand what I am trying to say.
What makes this issue more complex is that, once data fetch from those physicall SAP tables, I have to keep the content for all those internal tables during the entire program run . Second the most, I do not want to limit the program by defining FS "n" times in data declaration section. That is really important since I have no idea how many tables will be accessed.
If I follow the logic from your examples, I will end up overwritting the FS content every time I assign new internal table to FS.
In order to solve this issue, I was thinking that whenever I get the data from SAP table into internal table (field symbol) i export the content of internal table / FS to memory and then retrieve them when needed. This sounds like waky /fuzzy process and I am not aware of anything better. I am old fashion ABAP guy who got certified 1995 and have not seen ABAP for at least 5 years.
I would like that someone either tells me whether I am OK going forard with my "memory" solution or ... in few words gives me hint how to handle multiple dynamicall defined tables AT THE SAME TIME with its content using some OO code.
Thanks

I have erroneusly opened the same thread twice. Sorry

How to scale 32-bit signed integer data to floating-point voltage when acquring data in DAQmx by PXI4472?

I acquired data in DAQmx by PXI4472. For the high speed data logger, I used "DAQmx Read" to read unscaled 32-bit signed integer data.
Now, my question is how to scale 32-bit signed integer data to floating-point voltage?
I think that it's (20/(2**24))*I32 because the voltage range of PXI4472 is -10 to +10 and its resolution is 24 bits. But I cann't get correct voltage by that formula.

While you could hard code the scaling factor, it will be more flexible if you retrieve the scaling coefficients from the driver. To do this, you need to use the Analog Input>>General Properties>>Advanced>>Device Scaling Coefficients>>Device Scaling Coefficients properties under the DAQmx Channel Property Node. Look at the documentation for this property to see how it can be used to create a polynomial equation for scaling to volts.
Since you are creating a data logging solution, you may want to consider using a compressed data stream from the driver instead of the I32 data type. This will allow you to read the data back as a stream of u8's instead. Since the PXI-4472 is 24 bits, you will only have to write 3 bytes to disk for each sample instead of 4. You can check out the following examples for how to create an application using this compressed data stream. It also shows how to use the scaling coefficients to transform the unscaled data back to voltage values.

Last Sign-in Date

Hi,
I currently run a random reports to measure usage on a weekly basis. I do so by going to Company administration : Sign in audit and copy & pasting into Excel.
I have just seen I can create a custom report using "last sign in" and "user name".
Is there a way I can set this up so it only gives tell me who has signed in, in the last 7 days? Rather than having to go in every week and set a manual filter putting the date in myself?
Thanks,
D

Possible to use JavaScript to Import Data from XML file to pre-fill fields?

Hi,
I have a dynamic fill-in PDF that I want to "pre-fill" internally in my company before sending out to users who will change any pre-filled fields necessary and answer questions we did not already answer.
We do not have LiveCycle Reader Extensions, but we can use Acrobat to import data from an XML document to pre-fill the named fields. Is it possibly to do this task using folder-level Javascript or some other method? I can look into this, and post my findings, but I'd like to know if it's possible or if I need to use a different programming language.

Hi,
I am afraid that solution was for a specific client and I can't share it. If I get a chance I will mock up an example, but this wont be for a while. From memory it was just a straight importData method. This would normally fail silently in a non-certified form, but when the form is digitally signed/certified, it works without a hitch.
Good luck,
Niall

Using "done signing" increases file size 3 to 5 times !

The new feature in Acrobat Reader 10.1.2 onwards is great - I can add a signature and a date.
BUT if I use "done signing" the file size increases 3 to 5 times the original file size ! So I used File Save - and that worked well.
Then I updated to 10.1.6 - and now the signature that I added is not "fixed" - it can be deleted or moved !
We don't want to use digital signatures !!
Any suggestions ?
Thanks

When you click the "Done Signing" button, the signature appearance and any text you added is flattened and becomes regular page contents and it won't be able to be moved or deleted as you describe. I also don't see a file size increase as you describe. Are you using an image for the signature and if so, how large is it (in bytes)?
