Configuration Wizard - Master password error

Dear Experts,

I am doing the post-processing steps after a migration of a NetWeaver 7.4 system.

I wanted to execute the functional unit for BI Java automatic configuration under:

http://hostname:port/sld/fun

But I am getting the following error:

Validation error:Master password policy error:error during policy check

I was checking and found Note 2272433 from April 2016, but when I try to implement it, it says, that the note

can't be implemented :-(

Please kindly advise on how to proceed! Many thanks in advance!
