Metadata - Properties of Profile Parameters

Metadata of profile parameters can be displayed n transaction RZ11 (maintain profile parameters). Metadata is very important for profile maintenance. To display metadata of a profile parameter, proceed as follows:

Call transaction RZ11 (maintain profile paramers).
Enter a profile parameter name in the Parameter Name input field.
To confirm your entries, choose Display.

Below is an overview of the metadata

Table 1: Metadata Displayed in RZ11
Metadata Displayed	Explanation
Name	Parameter Name
Type	Possible types are: Character String: String of alphanumeric characters. The permitted character strings can be restricted. You can continue to work with regular expressions for checking. In both cases you would get the permitted values or the used regular expressions displayed under "Further Selection Criteria". Integer: Any whole number. Integer Interval: Permitted integers are restricted with an interval. The permitted interval is displayed in "Further Selection Criteria". Floating point number: Any floating point number. Floating point number interval: The permitted floating point numbers are restricted with an interval. The permitted interval is displayed in Further Selection Criteria. Enumeration: String of alphanumeric characters. The permitted character strings can be restricted. In this case the permitted values are displayed in Further Selection Criteria. Logical Expression: Boolean true value. Can be specified by values TRUE/FALSE, 0/1, ON/OFF.
Further selection criteria	Permitted character strings, interval, and the used regular expression depending on the type are displayed here.
Unit	The value of a profile parameter can be specified by the following units: No unit: If there is no practical unit. For example, if the parameter value is made up of a group of subparameters. Bytes: Bytes, megabytes, and gigabytes are possible. Time: Seconds, minutes, seconds, and days. Percent: Any floating percentage.
Parameter group	Assignment of a profile parameter to a group. Used for sorting and makes it easier to search for relevant profile parameters.
Parameter Description	Short description of the profile parameter. You can find a detailed description in the profile parameter documentation in transaction RZ11 (maintain profile parameters).
CSN component	CSN component that can used if there is a problem with the profile parameter.
System-wide parameter	Possible values: Yes/No Specifies whether the profile parameter is valid system-wide, or only for a specific application server instance.
Dynamic parameter	Specifies whether the profile parameter can be changed dynamically. If a profile parameter is changed dynamically, the new value is valid until the application server instance is restarted.
Vector parameter	There are two types - scalar and vector parameters. With scalar profile parameters you can only enter a single value. With vector profile parameters you can enter an array of values. The profile parameter is then assigned for each of these values a separate index, in the format `Profile parameter name_index`. The index is an integer. The indexes do not have to be assigned sequentially, they can normally contain gaps. Check the relevant profile parameter documentation for details. In transaction RZ11 you can display the single indexes of a profile parameter. Enter the name in the following format in the input field of transaction RZ11: `Profile parameter name_index`.
Contains subparameters	Subparameters are fixed parts of a profile parameter that cannot exist independently as profile parameters. If subparameters exist for a profile parameter, they can be displayed in RZ11 (pushbutton beneath the metadata Display Metadata for Subparameters). In the metadata overview of the subparameter, you can see information about the type, unit, and whether subparameters are obligatory.
Check function exists	Check function for special character strings that cannot be checked without this function.
