Hi All,
How to set maximum size in Text Form Field Options for a field in bi publisher RTF.

Form fields have some restrictions if your are using version lower than 11g.
They can accommodate only 393 chars. You can add the text in both status bar and help key, which can in total consume 393 chars.
If your code logic is more than that, it can be split into multiple form fields as Avinash suggested or you can use sub template logic and handle coding over there. Again in sub template code can be within/outside form fields.
So there is no option for user to increase the size of form field.

How set maximum of characters for the columns

Hello I use a JTable and I want to set maximum of characters for the columns.
For example column 1 max 10 characters, column 2 max 20 characters, etc..
How can I do this?

The principle is as follows: a table uses certain input components for editing a cell value, e.g. a JCheckBox for Boolean-type values or a JTextField for textual/numerical values. By default, a JTextField doesn't have any size limit, so you can enter as many chars as you want. In order to change this behaviour, you'll have to
1.) create a JTextField that does have a size limit and
2.) set a CellEditor on the JTable which uses this manipulated JTextField.
An easy way for 1.) is to create a custom Document (the internal data representation for text components, the M-part of the MVC -- see javax.swing.text.Document) that doesn't accept any text beyond a given limit, e.g.:
public class LimitedDocument extends PlainDocument {
private int max = 0;
public LimitedDocument(int max) {
    this.max = max;
public void insertString(int offset, String str, AttributeSet a) throws BadLocationException {
    // too long for the limit; get current contents, insert, and cut off trailing chars
    if ((getLength() + str.length()) > max) {
      StringBuffer buf = new StringBuffer(getText(0,getLength()));
      buf.insert(offset,str);
      remove(0,len); // remove current text contents
      super.insert(0,buf.toString().substring(0,max),a); // insert whole text
    // no problem, will fit
    else {
      super.insertString(offset,str,a);
}Then, in order to set the cell editor -- for example for the first column --, you can do as follows:
myTable.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(new JTextField(new LimitedDocument(5),"",5)));This will create a new DefaultCellEditor (see javax.swing.table) and initialize it with a given text field which will be responsible for any edition in this column. As the text field itself is created using a limit of 5, it should accept no text insertion beyond 5 chars.

How to set a date range for date field ?

Dear Experts,
Scenario:
I have a query in validating the date field in my BSP application. My application is for maintain infotype 0023 Other/Previous Employers online by employees in the company.
As per our design we are maintaining the all employment details of the employee both ( with in the current company / previous employment outside the company) in the same infotype.
Every employee will have a hiring date within the SAP HR system. We consider this date as the cutoff date between current and previous employment in our application. When the employee updating the details wia BSP page I need to check the following.
Record inside current company: Validation that, the user should only able to enter BEGIN DATE (BEGDA) greater than or equal HIRING DATE and END DATE(ENDDA) should be greater than FROM DATE (BEGDA).
Record outside current Company: Validation that, the user should only able to enter BEGIN DATE (BEGDA) less than or equal HIRING DATE and END DATE (ENDDA) should be greater than FROM DATE (BEGDA) and less than HIRING DATE.
Technical Requirement:
How to set a date range for date field, i.e. how we can limit the date range in a HTMLB date field? Can this it be achieved via standard functionality of HTMLB?
Following is the code to describe date field in my application.
 <htmlb:inputField id= "ENDDA_NEW_IN"
 type= "date"
 doValidate= "TRUE"
 showHelp= "TRUE"
 disabled= "FALSE"
 width= "183"
 style= "cssTextAreadate"
 value= "<%='99991231'%>"/>
Thanks a lot in advance for your assistance and help.

Can I set a time limit for connection to a certain WLAN?

I would like to set a time limit for how long a client can be continously connected to the WLAN that provides my guest internet access. The user name/password is hosted on my ACS and authentication is provided by my Cisco NAC. I am using 5508 controllers (7.02) and WCS.
Somewhere in this combination of stuff, there has to be a way to set a two hour time limit.

If you are looking for your guest to get kicked off which requires them to log back in .. One option would be to set the WLAN session timeout to 2 hours.

How to set a default value for particular field in SRM PO Portal

Dear Gurus,
Im desparetly need a help in web dynpro on how to set a default value for a field(flag) in PO header tab in portal.
My requirement is whenever the user press the edit button in PO screen,automatically a flag field should be set as abap_false.
I dont think this will handle in check badi or change badi. i tried this part in onbuttonpressed overwriteexit in CNR_VIEW views,i can get the function EDIT in debugging mode,but dont know how to proceed further.....
Many of them suggested to go with get attribute and set attribute for changing any particular field in web dynpro,but im not very familiar in using those get and set attributes.I request you people can give me sample code on how to identify my target field in the node and set the values while pressing EDIT Button.
Thanks in advance...

Dear Laurent,

But i searched in enhancement spot of WD_BADI, but couldnt get the exact way to change the coding,
My real requirement is, that particular flag should be enable and disable dynamically by checking a condition in my header values.So in that case i dont know how to proceed further to handle in the PO screen.
Kinly guide me how to get the particular node of field in the Purchase order screen.
Thanks you in advance,
Sorry for the inconvenience if any

Is there a character limit for a field in CrystalReports?

Is there a character limit for a field in CrystalReports?
Hello,
I'm trying to display a long text (+100.000 characters) stored in a MySql database in CrystalReports but CR is not showing the complete text. Is this because there is a length limit for fields in CR?
Thanks,
Eddy G.

This is not a great answer, but you can base your report on a SQL Command, then use something like this for the command(MS SQL):
select
case when length(table.field) > 65535
      then substring(table.field,1,65535)
      else table.field end as field_part1,
case when length(table.field) > 65536+65535
      then substring(table.field,65536, 65535)
      when length(table.field) between 65536 and 65536+65535
      then substring(table.field,65536, length(table.field)-65535)
      else '' end as field_part2
from table...
Then in the report, display both fields where you want the BLOB data.

An global maximum amount limit for single payments made via the ACH

Hi
Can any one guide how to config the gobal maximum amount limit for a single payments made via the ACH (Automated Clearing House) network.
Pl do the needful.
thank you.

Hi Tony,
Not exactly the solution, but going forward you can try split the invoices and process it separately at the time of invoicing itself. Otherwise you can try the option installment payment terms, but there may be at least one day difference in payment.

Looking at the source for 1.6.0_15 the default is 8192 and, other than the buffer size being greater than zero, there are no other constrains on the size so the limit will be the largest positive integer. Of course you may well run out of memory trying to allocate this amount of memory but ...

Char limit for .mov format?

Originally posted in the iTunes for Mac forum but to no avail; I would really like to know if there is a char limit in the comments fields of the movie .mov format? When typing in comments for a .mov I find that only a certain amount save leading me to believe either:
a) iTunes enforces a char limit
b) .mov has a char limit
Either way its a disaster for my media handling, I'm quite verbose.

Hamper..don't hold your breath for a fix since 255 sounds horribly like a limit defined by the underlying architecture... Chances are that there is a single data byte that is used to tell iTunes just how many characters there are in the Comments field. As you may/may not know, one byte can only record a max of 255 characters.
