Hi Sanjay,
Would you like to elaborate on what is the key identifier that should post using different posting rule from DT01/02 with NTRF?
The above thread is concerned with the situation where you receive a certain "textual key identifier" in note to payee field in the bank statement and by means of search string, you can divert the posting differently.
Would you like to share with us what is the strign you would like the system to search and post with different posting rules?
cheers
