in ax 2012 r2
when create new payment journal and go to lines then select customer account I got the below error
"unable to find unique dimension code combination record corresponding to the entered values"
There is ledger account mapped with every customer group.
AR-> Setup> Customer Group> Setup Tab. here you find this mapping.
Now check what group is mapped with selected customer and go to that Ledger Account.
In Ledger Master Form-> Dimension set rules Tab. here we defined the dimension sets which must be filled when we post any transaction which hit this Ledger.
U have to fill any one combination in your payment journal. and try again to post it.
Harry, I don't think there is a 'Setup' tab on the Customer Groups form, in AX 2012 R2
the issue was a wrong import of the screen from FP version into R2, we deleted the imported screen and issue solved thank you all
