[Forums] Custom Transaction Number

Hi, 

I am going to create an auto-generated transaction number with the following format: NN-DDMMYYYY-AA-BB

NN: transaction ID (auto-increment, reset every month)

DDMMYYYY: transaction date

AA: type of transaction (for example: SA for sales, PU for purchase; the type of transactions are stored in Static Entity TransactionType)

BB: transaction status (for example: 01 for new transaction, 02 for updated transaction; also stored in Static Entity TransactionStatus)

Does anyone have a suggestion how to do this? Thanks
