Document Folder Auto Code Template
There is an automatic code template and counter field in the folder definition After you give the code template a pre-code you want in the form of sample PR-###, you can have it automatically incremented with the # character you will put at the end of the pre-code.
No matter how many #'s you put in, it starts with 0, for example #### it starts from 0001 for ### it starts from 001. You should set this number according to the maximum number that your documents can reach. The counter indicates where the numerator will start. Each document will increase by 1 in preparation and saving. This is how you can set up your flow.
