Hi Vinod,
Here, you just need to post the Cash Flows generated using TBB1 after releasing them from TI90. One USD and one INR flow will be posted since their status is still showing up as 'S'.
No derived profit/loss flow will be generated in this case since if you see, there is no exchange rate difference arising from the USD flows converted to INR and the INR flows. Both are of the value 6,000,000.
This is standard system behaviour. Hence there is no need to change settings if no flows are getting generated for 105 from TPM18.
Regards,
Rohit
