| Domains (ttadv4100s000) |  |
| Use this session to maintain domains. A domain specifies the data type, the value range, (default) display format, length and so on. Domains can be linked to table fields, form fields, and program variables. You can copy the domain to your current package VRC. However you can only maintain domains of your current package VRC. You can also change the current package VRC of the user in the VRC of the current component.
Fields | Description
Package | The code of the package for which the domain is defined.
Package | The description of the package.
VRC | The version code of the package for which the domain is defined.
VRC | The release of the package for which the domain is defined.
VRC | The customer extension of the package for which the domain is defined. Note It is only relevant for customized software.
Domain | Select the domain's identification code. A domain is uniquely identified by the combination of package code and domain code.
Expired | If this check box is selected, the domain for this package VRC and the package VRCs derived from it have expired.
Description | The description of the domain.
Data Type | The internal representation of data. Possible values
String Length | The length in characters if the data type of the domain is string. The number of positions on which the characters can be placed if the data type is multi-byte string.
Alignment | Select the alignment method for strings.
Conversion | Select the conversion method for strings.
Internal Format | This field indicates how a number, entered in a form input field with the string data type must be internally formatted. For example, if a number like 37 must be stored as 00000037, use the format 99999999.
Length | The default display or print length of a field or variable with enumerate or set data type in a form or report. You can overwrite this length on the data of a field in a form or report.
Digits before Decimal | The maximum number of digits for the long, integer and byte data types. For the float and double data types, this is the maximum number of digits before the decimal point.
Digits after Decimal | The maximum number of digits after the decimal sign. Note Only relevant for double and float data types.
Divide Factor | The factor by which the entry in a field is divided. Example Divide factor = 100 The user enters 25009 in the field. Tools divides 25009 by 100 and displays 250.09. It can be useful for fields containing amounts. Note This entry can only be filled in a domain of the double or float data type.
Rounding Method | Select the way in which a field with the float or double data type can be rounded. Rounding takes place at the last digit as specified by the number of digits after the decimal point. In the following examples, the number of digits after the decimal sign is one.
Entered by user | Round off | Round off upwards | Round off downwards
--- | --- | --- | ---
1.51 | 1.5 | 1.6 | 1.5
2.78 | 2.8 | 2.8 | 2.7
1.55 | 1.6 | 1.6 | 1.5
Format | The display format which is used in forms and reports to display specific data. Note The display format can be used for the byte, integer, long, double, float, string (with only digits) and date data types.
Date/Time Format | The date. Related topics To enter a date
Date/Time Format | The time. Related topics To enter a time
Legal Characters | The legal characters that can be entered in a form input field. Example If only numbers can be entered in a field with string, data type, the legal characters are specified as: The characters ' " ^ \ must be preceded by a backslash [\]: \\ and \". Note If you do not explicitly specify any legal characters, all characters are legal. If you define some characters as legal, all other characters are illegal, and vice-versa.
Illegal Characters | The illegal characters that cannot be entered in a form input field. The characters ' " ^ \ must be preceded by a backslash [\]: \\ and \". Note This field cannot be accessed for domains of enumerate and set types. If you do not explicitly specify any illegal characters, all characters are legal. If you define some characters as illegal, all other characters are legal, and vice-versa.
Range | The range which is used to check the validity of the input. If you enter a value in a form input field outside the specified range, Tools produces a range message, and Tools will ask for input again. For simple validation checks, you can use the data type, legal and illegal characters, the length of the field and the number of digits before and after the decimal point. For more complicated validation checks, you need this range attribute. The range can be an expression with evaluated value true (valid value) or false (invalid value) (true <> 0, false = 0). Other variables can also be used in the expression. The current value can be tested in the expression by using 2 dollar signs: $$ Examples: A number between 30 and 40 and not equal to a specified field: $$ in [30,40] and $$ <> ppmmm001.reserved A string starting with a capital: $$ in ^[A-Z].*$ (regular expression) The following operators can be used (listed in order of decreasing precedence):
( ) | expr in brackets | e.g. 2*(3+5)
IN | range test | e.g. $$ in [10,20]
- | Unary minus | e.g. -10
^ | Raise to power | e.g. 2^3 = 8
* / \ | Multiply/ Divide/Remainder
& | String concat | e.g. "A"&"B"
+ - | Addition / Subtracting
= <> <= >= < > | Relational operators
not | Logical negation
and | Logical and
or | Logical or
Range Message | Select the code of the messages (including package code) which is given if you enter a value outside the specified range.
Range Message | The message as shown when activated.
