ci/woodpecker/push/main Pipeline failed
Customer revenue/concentration now filters bill_type IN (1,4,14) (XSD/XSTHD/XSHHD). Non-sales docs (JHD purchase, YFKD prepay, YSKD accept, QTRK, SKD, YBFYD) carry SUPPLIER unit_id and were polluting 'customer concentration' (old Top1/Top2 were our biggest suppliers; root cause of 6.04x base gap). Unify sign filter to (sum_money+sum_tax_money)>0 (equivalent to money_only on current data, diff 0 rows) and correct the withdrawn 407-row/17.2% wording in cpa_caliber docstring. Deriver: anchors from cpa_caliber single source; new --concentration overwrite and --only concentration (minimal 9-row write face) with pre-overwrite backup. Tests: fixture gains bill_type/sum_tax_money; +5 whitelist cases (44 passed targeted).

"""CPA(客户获利性)取数口径 —— 单一事实源(2026-10-04,任务 finance-20261003-cpa-customer-profitability-mvp-fullstack。
|
||
|
||
2026-10-04 P0 口径纠错(任务 finance-20261004T0905-cpa-revenue-caliber-p0,依据财务独立复验件
|
||
`finance-20261004-cpa-mvp-independent-verify` §5.3):增列**单据类型白名单**(只取销售类),
|
||
避免把采购/资金/库存/费用单据的**供应商**当成客户。
|
||
|
||
为什么有本模块
|
||
--------------
|
||
客户级收入聚合此前只有一处实现(`app/api/alert_rules.py::_customer_revenue_shares`,
|
||
供客户集中度预警使用)。CPA 派生器必须复用**同一套**聚合,否则同一指标出现两份结果
|
||
(任务 handoff 明写「勿另写第二套客户收入聚合,抽公共函数」)。
|
||
本模块即那唯一的公共函数;`alert_rules._customer_revenue_shares` 与本派生器都调它。
|
||
|
||
基座
|
||
----
|
||
`zxt_masterbill`(智享通单据流,仅 entity1 有数据:15,755 行 / 284 个往来单位 /
|
||
2021-03 ~ 2026-09-30)。**无** unit 名称列 ⇒ 客户标识只用 `unit_id`。
|
||
|
||
口径(勿擅改)
|
||
--------------
|
||
* **单据类型白名单 = 销售类 `bill_type IN (1, 4, 14)`**(1=XSD 销售单 / 4=XSTHD 销售退货 /
|
||
14=XSHHD 销售换货;等价判据 `bill_sn LIKE 'XSD%'/'XSTH%'/'XSHH%'` 实测逐行同集)。
|
||
非销售单据一律排除:0=JHD 进货 / 128=YSKD 验收 / 17=QTRK 其它入库 / 129=YFKD 预付款 /
|
||
101=SKD 收款 / 103=YBFYD 费用 / 104=QTSRD 其它收入 / 18=QTCK 其它出库。
|
||
**依据**:这些单据的 `unit_id` 是**供应商**(`abst` 实读「向【酣客酒业(广州)】进货」「预付款单」),
|
||
混入会把「客户集中度」变成「往来单位(含供应商)集中度」——旧口径 Top1/Top2 恰是本公司最大供应商,
|
||
也是「4,883.52 万 ÷ 账套 5001 808.80 万 = 6.04× 基座差」的真因。
|
||
⚠️ 该纠错**改变对外数字**(户数 73→65、Top1 25.3835%→22.5150%、Top2 归属由供应商改真实客户);
|
||
属**事实性纠错**(财务定死 + 任总知会),非选型。
|
||
* `C_CUST_REVENUE` / 快照明细 `revenue` = Σ`zxt_masterbill.sum_money`(按 `unit_id`、期内、**不含税原值**)。
|
||
过滤:`entity_id=? AND unit_id>0 AND bill_type IN (1,4,14) AND (sum_money+sum_tax_money)>0
|
||
AND bill_date IS NOT NULL`。
|
||
* **取舍口径(符号过滤)**:`(sum_money + sum_tax_money) > 0`(`tax_incl`)与 `sum_money > 0`
|
||
(`money_only`)在本库当前数据上**完全等价**(2026-01~09 双向差集 **0 行**;全表亦 0 行)。
|
||
原报告「407 行红冲(含税为正、金额为负)⇒ 预警侧低估客户收入 17.2%」经财务复验**证否并作废**:
|
||
407 行 = 1,651(无过滤全行) − 1,244(符号过滤),由 **302 行零额 + 105 行负额**组成(负额两式同样排除,
|
||
Σ`sum_money`=−841.22 万 / Σ含税=−1,717.97 万);所谓「1,651 行 / 78 户 / 4,042.31 万」实为
|
||
**无符号过滤(全行)**的结果(原报告**标签错置**);「17.23%」= 4,883.52÷4,042.31−1,
|
||
是「加符号过滤 vs **不滤**」之差(方向为**高估**),**不是**两路径之差。
|
||
⇒ 全体系**统一书面口径** `(sum_money + sum_tax_money) > 0`(预警与 CPA 同源同式,差集 0 ⇒ 行为零变化)。
|
||
* 对拍锚点(2026-01~09,销售类白名单口径):**65 户 / 1,207.74 万元 / Top1=22.5150%(unit152) /
|
||
Top2 单户=13.9734%(unit155) / Top4 累计=46.9407% / Top10 累计=69.7511%**(见 `ANCHORS_2026_01_09`)。
|
||
与账套 5001 逐月同向同量级(01: 229.02 vs 180.87;07: 81.55 vs 81.08;08: 15.83 vs 14.45)⇒ 可勾稽。
|
||
* `C_CUST_CONCENTRATION`(**沿用** `kpi_definitions.formula`)= 前5大客户收入 ÷ 期内客户收入合计 ×100。
|
||
(任务书 §2.1 写的 Top1 与现网定义「前5大」不一致 ⇒ 见报告「口径冲突登记」;
|
||
两者本模块都算:`top_n=1` / `top_n=5`。)
|
||
* `C_CUST_COGS_ALLOC` / `C_CUST_CHAN_SUB` / `C_CUST_CONTRIB` / `C_CUST_CONTRIB_RATE`:
|
||
**fail-closed,本模块不产出可写值**(理由见 `FAIL_CLOSED_REASONS`)——任何调用方
|
||
不得据此写 0 / 分摊值(任务 §2.2 与验收「禁止事项自证」)。
|
||
