TPM82_Portfolio transfer

Hi All,

I would like to know can we use the TPM82 (Portfolio transfer) after transactions have been posted?

I tried to open in the screen but it says function is not allowed. Please can some one explain me in detail about the customization and transfer process.

I Have 40 transactions which is posted already need to change the portfolio name for all the transactions.

Please share your valuable points would be greatly appreciated.

Thanks in advance,

Prasad
