Calling Billing schema - particule rate through FM
We have migrated bill document through EBF and using EBF correction method to correct these bill doc which will result in manual bill.
In case if we want to change reactive energy charges, we facing problem in calculating it . Since it derived from the complex logic rather than simple (QTY * Price = amount) . At the input we are getting qty to be change.
I want to know is it possible to call only particular rate (which is having multiple lines)of schema through any FM or by any other means. which will execute and returns value of that rate. hence can pass that to Qty/ MR field in manual bill.
or any events which can be called while creating manual bill to do above functionality
Thanks in advance.
