TRM - Post to the reconciliation account in business partner/customer master

Dear all,

I am working on the scenario of fixed term deposit, ex:

Dr Position

Cr Customer account

I added the payment detail with customer Id in TM01, then executed TBB1 but I got the error

"No posting specifications assigned to update type MM1100-, payment trans. X"

When I create a new symbol, new posting spec to assign to update type "Increase" with payment transaction type X and assign GL account for the symbol in config, it posts correctly.

But the problem is I have different recon accounts in customers. What required is it is possible to post to the recon account in business partner/customer master. Please help to advise.

Thanks and Regards
