Tax BSV is not getting updated same as the otehr distributions BSV

In the implementation, we have set up the Recoverable tax rate in Payables for each tax rate for the OU IRE as 4001.0000.155701.0000.0.0

For thisnOU, we have BSVs 4001, 4170,4160 etc.

The business requirement is that the BSV on all the distributions in Payables invoice should be same.

means if Libaility acct BSV is 4160,Expense acct should be 4160 and Tax should be 4160.

We are able to acheive this for Liability and Expense acct, but when it comes to Recoverable tax ,it is picking up the BSV hardcorded in the Recoverable tax rate setup.

What setup need to be chnaged so that we can derive the BSVs in tax distribution same as the other distribtuions in Payables Invoice.
