How to define an array of fixed length

hello, i have a basic application in which i need to define an array of size 19; and add 19 elements to it.
Once 19 elements have been written to the array, i want to start writing to the array from index 0.
It's like in C language, where-in you define array_size in init, and once the array is full, you overwrite the 1st element and so on.
i hope my question makes sense...
any help is appreciated.

You can create an nXSD using Native Format Builder and use lookAhead attribute to read values at specific position and use that as the choice. You can find an example here

How to define Approval Hirearchy for Fixed Assets?

Hello All,
Couls someone please tell me How to define Approval Hirearchy for Fixed Assets which should be different as compared to normal item purchase.Reply me ASAP
Regards
Aditya

Hi,
The AP invoice approval used AME rules for finding the approver. You can base you AME rules on virutally anything.
In this particular case, you can base your AME rules on one of the followings:
1. If any of the Distribution Accounts contain Fixed Assets natural account
2. You can define a separate document category which should be used with invoices for FA Purchase and use the category in AME rules to find approver
3. You can have a DFF at the Invoice Header level to indicate that this is a fixed asset purchase invoice and have this DFF to be used in AME rules.

How to define an array in ABAP

Hi experts,
   Can we define an array in ABAP. if yes then How. plz help.
Regards.
Vaibhav Tiwari.

Hi,
There are no array concept in abap, instead of array there are internal table and field strings in abap.
Ex.
data : begin of itab occurs 10,
          matnr like mara-matnr
          mbrsh like mara-mbrsh,
          end of itab.
data : begin of itab,
          matnr like mara-matnr
          mbrsh like mara-mbrsh,
          end of itab.

Do you mean padding a String?
      * This method pads the string s to size n using char c to make up for missing characters.
     public static String padString(String s, int n, char c, boolean paddingLeft) {
          StringBuffer str = new StringBuffer(s);
          int strLength = str.length();
          if (n > 0 && n > strLength) {
               for (int i = 0; i <= n; i++) {
                    if (paddingLeft) {
                         if (i < n - strLength) str.insert(0, c);

How to map an array to fixed fields using Biztalk mapper

I need to remap an array of objects like this:
<Root>
<ListOfObjs>
<Obj>
<Attr1>0000</Attr1>
<Attr2>Hello!</Attr2>
</Obj>
<Obj>
<Attr1>1111</Attr1>
<Attr2>Hello1!</Attr2>
</Obj>
</ListOfObjs>
</Root>
in an output like this:
<Root>
<Obj1_Attr1>0000</Obj1_Attr1>
<Obj1_Attr2>Hello!</Obj1_Attr2>
<Obj2_Attr1>1111</Obj2_Attr1>
<Obj2_Attr2>Hello1!</Obj2_Attr2>
</Root>
So in my XSD schema I have something like this:

In addiction I have to evaluate every single value because when I found some conditions (like if value=0000 output should be NULL).
What would be the best way to do it? I'm thinking to develop a custom functoid but I'm not sure it would be the best way, probably it could be done even using XSLT inline transforms, can you point me in the best direction?
Thank you

Hi,
You cannot directly map an array output to any single field in BizTalk mapper.
Couple of options :
1) create
the Xslt or inline C# code
Refer:
http://seroter.wordpress.com/2008/10/07/splitting-delimited-values-in-biztalk-maps/
2) Shankycheil has
provided a solution to similar requirement in the below link, u can also refer that.

Rachit
Thank you, I already seen both posts, but I'm not sure they are what I need or I can't understand well how to use them.
Speaking about the first solution, as I told before, in the example I should have an array already formed and delimited by a char (something like "obj1attr1-obj1attr2-ob2attr1-obj2attr2". In this situation probably this example could be a good
point to start from, but how to transform my complex input object in a similar formatted string?
About the second I don't understand well what is the working solution that they have adopted. Is the 4 steps solution suggested by Shankycheil? If yes, how can I loop between all array elements and extract all their values?

String of format
Name : 8 chars
Age : 2chars.
so the required mapping should result in
"George 21".
Note: 2 blanks after "George" to allow for 8 characters. Is this kind of mapping possible using ALSB xquery? I have tried to create a MFL representation for the string , and used it in the xquery as the targer but it is generating
"George21".Only data present in source is getting mapped :(

My advice would be to use MFL transformation for that.
Documentation about MFL can be found at edocs: http://edocs.bea.com/alsb/docs26/fbhelp/index.html

How to render h:outputText of fixed length inside h:panelGrid

Hi,
I am using h:outputText inside h:panelGrid.
But while renderring output text, whatever is the text length , the width of the h:outPutText should be same.
I am getting the results diplayed as below if length varies.

Pls help me...

sorry it's not working...
Here is my code snippet...

Array of fixed-length vectors

The compiler accepts:
Vector[]ranga=new Vector(5)[100];
but how can I fill it permanently
without executing program statements?
like
Vector[]rangb=new Vector(5)[] { { "s1",500,"s2",499.,"s3" },{ "s4",510,"s5",499.5,"s6" } };
which the compiler rejects.
Or is there a better way to get the
permanent information into the program?

You would have to create your own DataObject class. That way it could contain whatever information you wanted without the need for complicated arrays.
I don't really understand what you're trying to avoid by initializing the data in a "simple" way. Using a for loop seems pretty simple to me, even simpler than trying to use braces and whatnot.
But creating your own class is the simplest way. Here's a hint to get you started:
public class DataClass{
   int number;
   String text;
   public int getNumber(){
      return number;
   public void setNumber(int newNumber){
      number = newNumber;
public class MainClass{
   DataObject[] dataObjects = new DataObject[100];
   for(int i = 0; i < 100; i++){
      dataObjects[i] = new DataObject();
      dataObjects.setNumber(whatever you want it to be);

File Sender, Content Conversion - how to define variable length last field?

XI 3.0 SP17
With a File Sender communication channel, that uses Content Conversion - how do I define a 'variable length' last field?
The scenario - the input file has four fields, of which the first three are a known fixed length, and the last (fourth, trailing) field is variable in length.
Using a Message Protocol of 'File Content Conversion', how do I define that last variable length field (field name 'WOData' below) in the Content Conversion Parameters section?
My current parameters are:
Recordset Structure - Row,*
ignoreRecordsetName - true
Row.fieldFixedLengths - 1,12,5,99999
Row.fieldNames - WOType,WONum,WOLine,WOData
I've tried the following for 'Row.fieldFixedLengths' to no avail -
'1,12,5,*'
'1,12,5,0'
'1,12,5,'
'1,12,5'
The last two were grasping at straws )
The only thing I've got to work is specifying a 'large' value for the final field (99999 above).
In addition, does anyone know if specifying a large value (e.g. 99999) for the final trailing field will give rise to performance issues when the file is being processed?
In the help for "Converting File Content in a Sender Adapter", it states -
<Begin Quote>
NameA.fieldFixedLengths
If you make a specification here, the system expects a character string that contains the lengths of the structure columns as arguments separated by commas.
If you also specify a separator for the columns, you must not add its length to the length of the columns.
This entry is mandatory if you have not made an entry for NameA.fieldSeparator.

<< note that fieldFixedLengths will not take any wildcard entries like *. So in these case it is ideal to provide a maximum char length. But note that while the file is being created that many spaces will be created in your file !!! >>
Hi Shabarish,
Yes, no wildcard is the conclusion I came to, hence my maximum )
The message size did not increase by any 'blank padding'. When I look in [Message Display Tool (Detail Display)] 'Audit Log for Message: X' -
2006-10-17 18:22:42 Success Channel X: Entire file content converted to XML format
2006-10-17 18:22:42 Success Send binary file "X" from FTP server "X", size 103290 bytes with QoS EO
2006-10-17 18:22:42 Success Application attempting to send an XI message asynchronously using connection AFW.
2006-10-17 18:22:42 Success Trying to put the message into the send queue.
2006-10-17 18:22:42 Success Message successfully put into the queue.
2006-10-17 18:22:42 Success The application sent the message asynchronously using connection AFW. Returning to application.
The input flat file in non-XML format was 92,132 bytes and the message payload into XI was 103,290 bytes.
My understanding is that trailing spaces are stripped from XML nodes.

How to handle a fixed length file without newline?

Hi Experts,
I'd like to handle a fixed length file without newline by sender file adapter.
A file like following.
It contains three recores."AAXBBBXCCCCX" is one record.
AA1BBB1CCCC1AA2BBB2CCCC2AA3BBB3CCCC3
I tried that following two parameters set. But only first recored was read.
fieldFixedLengths
fieldFixedLengthType
Please tell me how to handle.
Thanks
Shinya Kawagoe.

For this case we wrote a simple Adapter Module inserting an end of line character after an offset.
This way it can be reused in many interfaces.
And reading the whole file may not be an option in case of large source files. May cause performance / memory issues.
eolbean.offset = <recordLlen>
XMLPayload xmlpayload = msg.getDocument();
byte[] content = xmlpayload.getContent();
byte crlf = 0x0A;
int current = 0;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int lines = content.length / recordLen;
do
     lines--;
     baos.write(content, current, recordLen);
     if (lines > 0) // if other lines, eol required
          baos.write(crlf);
          current += recordLen;
} while (lines > 0);
xmlpayload.setContent(baos.toByteArray());
baos.close();
Audit.addAuditLogEntry(key, AuditLogStatus.SUCCESS,     MODULE + " Done EOLing.");

How to create Fixed Length Flat File from Open Hub in BI 7.0

My requirement is to produce a Fixed length Flat file by Open Hub destination. My Open Hub has four fields. Now the requirement is to create another extra field in Open Hub which will contain all of the four fields value. In addition to that the fields should be fixed length that means if for any field no value is there and the field length/type is CHAR4 then 4 spaces should be there as the field value. SO, basically the Open Hub output will be single field which will contain information of four fields.
How to get this using End Routine of Transformation (from DSO to Open Hub) ?

Hi,
You can map the four input fields to the new field in the Open Hub, and change rule type to "Routine".
For example, if your source fields are called "first", "second", "third" and "forth", the ABAP routine could be similar to:
DATA: l_t_1 TYPE C LENGTH 4,
      l_t_2 TYPE C LENGTH 4,
      l_t_3 TYPE C LENGTH 4,
      l_t_4 TYPE C LENGTH 4.
IF source_fields-first IS INITIAL.
l_t_1 = '    '.
else.
MOVE source_fields-first TO l_t_1.
endif.
IF source_fields-second IS INITIAL.
l_t_2 = '    '.
else.
MOVE source_fields-second TO l_t_2.
endif.
IF source_fields-third IS INITIAL.
l_t_3 = '    '.
else.
MOVE source_fields-third TO l_t_3.
endif.
IF source_fields-forth IS INITIAL.
l_t_4 = '    '.
else.
MOVE source_fields-forth TO l_t_4.
endif.
CONCATENATE l_t_1 l_t_2 l_t_3 l_t_4 into result.
In the example, the program uses four blank spaces if any of the fields has no value.
Additionally, if non-initial values in input fields could be shorter than 4 characters (if the input fields have no fixed length), you could use STRLEN to evaluate if it is necessary to add blank spaces to complete the fixed length of 4.
I hope this helps you.
Regards,
Maximiliano

How to define Length of char. and KF

During infoobject creation, how to define the length of char. and KF, is it related to master data text length ? Should we take other things into account? When we see one field in table, the length of the field was defined with 2, but its master data text length was more than 2, what's the reason for this things?
Edited by: hi ni on Apr 18, 2008 12:12 PM

hi,
how to define the length of char. and KF, is it related to master data text length ?
ther business will have defined length and type for any characteristics. ex - Materail number may have lenth of max 15 and is Char type.
but for text max size is by default 40 chars.
Should we take other things into account?
get spec from client, that could be better and also consider the field used to map ur char/KF from source system.

How to use OracleDbType.Array provided by ODP with User defined type ?

Can anyone help me how to use OracleDbType.Array provided by ODP.NET ?
I need to pass string array to a oracle stored procedure .
User defined array type defined in oracle is :
CREATE TYPE TYPE_NAME IS TABLE OF varchar2(20) ;
This type is defined outside of any package , and i have tested that if definition of type is modified to
CREATE TYPE TYPE_NAME IS TABLE OF varchar2(20) index by binary_integer , i am able to pass array as AssociativeArray to my Stored Procedure.
But how to pass array object if the Type's definition does not contain index by clause ?
Please help how to pass Array object to Oracle Stored Procedure ?

The solution described in Passing Array of UDT or Collection as IN OUT using OracleDbType.InputOutput
is working for me.

How to build a fixed-length string representing an integer

Hi,
I would like know how can I use the API to get a String representing an int with fixed length. I mean, I would like something similar to Integer.parseInt(), but I need to set the length of that String in such a way that, for instance, if I need the String to be 5 character long, and the int is 37, the String would be 00037
Thanks in advance and best regards,
Miguel ?ngel

I wrote pad() methods in my string helper that can be used for this purpose.
In particular, you want to prepad with '0' to a length of 5:
com.Ostermiller.StringHelper.prePad(Integer.toString(37), 5, '0');
