You can use an edit validate rule. You can also create a DT/Activity where first you can check the validation of the user input against alphabets and special characters, then after the validation passes you can substring the input into 3 params and concatenate those with '-' in between. 

Hi @Praveenn881,

we achieve this by creating edit input rule in that rule add the below code.

if (theValue.length() > 3 && theValue.charAt(3)!='-')

{  StringBuilder sb = new StringBuilder(theValue);

  theValue=sb.insert(3, '-').toString();

}

Thanks,

Sai G
