DME not working - Sort/Key fields in DME tree

Hello experts,

I'm working on developing DME tree. I copied from the existing standard tree & then made some changes specific to bank requirement.

It worked initially, but suddenly now its not giving the correct output.

No of transaction not coming, hence the sum total coming zero. Also only the values for constant are getting displayed, nothing else displayed. Reading the earlier threads, checked the sort/key fields and tried multiple combinations, however it is still not working.

Could someone help in this case please.

Thanks you
