The following table presents the profile parameters with which you can set password and logon rules. For information about the procedure for changing profile parameters, see 
Changing and Switching Profile Parameters.
Changing and Switching Profile Parameters.
To make the parameters globally effective in an SAP system (system profile parameters), set them in the default system profile DEFAULT.PFL. However, to make them instance-specific, you must set them in the profiles of each application server in your SAP system.
To display the documentation for one of the parameters, choose Tools ® CCMS ® Configuration ® Profile Maintenance (transaction RZ10), specify the parameter name, and choose Display.On the following screen, choose the Documentation pushbutton.
Password Checks
Parameter | Explanation |
login/min_password_lng | Defines the minimum length of the password. Default value: 3; permissible values: 3 – 8 |
login/min_password_digits | Defines the minimum number of digits (0-9) in passwords. Default value: 0; permissible values: 0 – 8 Available as of SAP Web AS 6.10 |
login/min_password_letters | Defines the minimum number of letters (A-Z) in passwords. Default value: 0; permissible values: 0 – 8 Available as of SAP Web AS 6.10 |
login/min_password_specials | Defines the minimum number of special characters in the password Permissible special characters are $%&/()=?'`*+~#-_.,;:{[]}\<>│ and space Default value: 0; permissible values: 0 – 8 Available as of SAP Web AS 6.10 |
login/password_charset | This parameter defines the characters of which a password can consist. Permissible values: ● 0 (restrictive): The password can only consist of digits, letters, and the following (ASCII) special characters :!"@ $%&/()=?'`*+~#-_.,;:{[]}\<>| and space ● 1 (backward compatible, default value): The password can consist of any characters including national special characters (such as ä, ç, ß from ISO Latin-1, 8859-1). However, all characters that are not contained in the set above (for value = 0) are mapped to the same special character, and the system therefore does not differentiate between them. ● 2 (not backward compatible): The password can consist of any characters. It is converted internally into the Unicode format UTF-8. If your system does not support Unicode, you may not be able to enter all characters on the logon screen. This restriction is limited by the code page specified by the system language.  With login/password_charset = 2, passwords are stored in a format that systems with older kernels cannot interpret. You must therefore only set the profile parameter to the value2 after you have ensured that all systems involved support the new password coding. Available in the standard system as of SAP Web AS 6.40. |
