The German company SAP AG has developed a policy for passwords that is set by default for all reference systems developed by SAP.
A password in compliance with the SAP passwords policy contains:
at least eight characters (the more, the better)
at least three of the following elements:
Capitcal letters (A-Z)
Small letters (a-z)
Numbers (0-9)
Special characters (*,+,&,%, etc.)
NOTE: The master password may not be identical with the user ID employed in SAP. This SAP user ID consists of a letter (D, I or C) followed by a six-digit number.
