Dear community,
I would like to ask how do we create formula in order to get the result as below:
If the account start with number of 2 series, then the type will be BS
if the account start with any letters and follow by the number of 2 series , then the type will be BS
if the account start with any letters and follow by the number of 9 series, then the type will be Control
if the account start with any letters and follow by the number of 1 series, then the type will be BS
if the account start with any letters and follow by the number of 3 series, then the type will be BS
If the account start with number of 9 series, then the type will be Control
If the account start with number of 4 series, then the type will be PL
if the account start with any letters and follow by the number of 4 series, then the type will be PL

Thank you
