## 1. Role

### JKKWrisvcAutoAplyCC.setSvcChrgYmdInfToStat910()

This method handles billing date assignment for discount services that have reached status **"910: Contract Cancelled"** (解約済). It is invoked as part of the broader discount service automatic application (割引サービス自動適用) workflow, specifically within the cancellation (解約) operation branch. The method's core responsibility is to derive and set three key fields on the input map `inMapWribsvkDchskmst`: (1) the service billing start date (サービス課金開始年月日), (2) the service billing end date (サービス課金終了年月日), and (3) a flag indicating the billing end date was computed manually (サービス課金終了年月日算出フラグ).

The method implements a **routed/dispatch pattern**: it first checks whether a "standard installation fee campaign" (標準工事費割引キャンペーン) is in effect, and if so, processes base service contract data from the EKK0081B029 service call to find the earliest-disconnected contracted service whose application number matches the current application. If not, it falls through to the standard discount service target contract list loop. Within that loop, it iterates over each target contract, queries the contract details, and identifies the one with the latest billing end date among those with status 910.

If any contract was found with status 910 (`ret = true`), the method then computes the final billing start and end dates. For **replacement-type contracts** (置き換え型 — identified via `isWribSvcCdToTikanType`), it delegates to `getSvcChrgStaYmd` and `getSvcChrgEndYmd` which use the service cancellation start date (サービス解約起算年月日) as a parameter instead of the regular billing end date (modified in OM-2017-0000628). If the computed end date is not the sentinel "non-billing" value, the original parent end date is restored. A special case handles "non-billing" scenarios where the start date is blank and the end date is MAX_YMD — it reverses the dates so the billing period runs from day 1 after the parent's end date through the parent's end date.

Finally, for contracts under the **installation fee discount campaign** (工事費割引キャンペーン), if the service cancellation start date's day-of-month is not "01", the billing end date is adjusted to the end of the previous month. For long-term continued discount service code `W00000041` (長期継続割引), an additional end date adjustment is performed via `setEndYmdForWribType32`. A retroactive determination check is always invoked before the method returns.
