Billing Date is not being Updated in FICA Tables

Hello Experts,

I have tried to include TDLR charges in ECS incentive calculations. As code is picking parameters from DFKKOP Table (FICA Table) using Main and Sub Transaction. We have found that this charge is not being updated in any Fica Tables. I have also verified that all the tables with respect to Billing contains TDLR Charges. it is not updated in all FICA tables.

Experts kindly suggest us to how to resolve this issue.
