## Narrative

**Business context:** Login-language resolver. Returns the per-user UI language code (`sLanguage`) for a username-or-id within a `(sBrandsId, sSubsidiaryId)` tenant. Used to localize numeric formatting and field labels in the 采购/生产明细 reports and in receivable/payable summary procs.

**What it does:** `SELECT sLanguage INTO p_sReturn FROM sftlogininfo WHERE sBrandsId = … AND sSubsidiaryId = … AND (sUserName = sLogin_id OR sId = sLogin_id) LIMIT 1`.

**Invocation:** embedded in form-master sSqlStr for the same five detail forms as `Fun_GetLoginUser` (采购申请明细, 采购订单明细, 生产补料明细, 生产领料明细, 生产退料明细). Also called from `Sp_Calc_sPmt`, `Sp_Calc_sRct`, `Sp_Manufacture_ProductionArrange2`, `Sp_NotReceivables_hz`.
