In R3 role design , "filling character" for org level required
I am designing a role in R3 system , wherein I want to maintain a particular set of values in Org Level. For example , my values for org level are as below
where second character can be any character , but first character and last two characters are fix. So I am searching any filling character which can replace second character such that it includes all the values for second character. eg. something like A+YZ.
Can anyone please suggest me this filling character ?
