How To Fix BIL032 - Incorrect interval for simulation &1 - &2 for contract &3 in BAdI &4

BIL032 - Overview

• Message type: E = Error

• Message class: BIL - General billing

• Message number: 032

• Message text: Incorrect interval for simulation &1 - &2 for contract &3 in BAdI &4

What causes this issue?

The BAdI method returned an incorrect interval for the simulation. This
can have one of the following reasons:
Billing documents already exist for the contract that is to be
simulated. The simulation period is not immediately after the last bi
lling period.
If the last billing run was a periodic billing run, the start date for
simulation must be earlier than or the same as the end date of the
billing period from the schedule record for the portion (ERCH-PTERMTDAT)
+ 1 day.
If the last billing run was executed without a schedule record for the
portion (for example, unplanned interim billing), the start date for
simulation must be earlier than or the same as the end of the billing
period + 1 day.
The start date for simulation is before the move-in date.
You have only specified the start date or the end date for simulation.

System Response

The system cancels simulation.

How to fix this error?

Check the BAdI implementation.

• What is the cause and solution for SAP error message BIL032 - Incorrect interval for simulation &1 - &2 for contract &3 in BAdI &4 ?

  The SAP error message BIL032 indicates that there is an issue with the interval specified for a simulation in a billing contract. This error typically arises when the start and end dates of the interval are not valid or do not align correctly with the contract's billing periods.
  
  Cause:
  
  Incorrect Date Range: The start date is after the end date, or the dates do not correspond to the billing periods defined in the contract.
  Contract Configuration: The contract may not be set up correctly, leading to invalid intervals for the simulation.
  BAdI Implementation: If there is a custom implementation of a Business Add-In (BAdI) that modifies the billing logic, it may be causing the interval to be calculated incorrectly.
  
  
  Solution:
  
  Check Date Inputs: Verify the start and end dates provided for the simulation. Ensure that the start date is earlier than the end date and that both dates fall within the valid billing periods of the
