Narrative

Business context: JSON-array lookup — given a JSON array sJson and a key/value pair (skey, sValue), returns the first array element whose $.skey = sValue, or '' if no match. The companion to Fun_HasJsonKey / Fun_RemoveJsonKey for filter-payload parsing in scheduler procedures.

What it does: Validates sJson is JSON, iterates each top-level element, JSON_EXTRACTs $.skey, strips quotes, compares against sValue; returns the matching element on first hit.

Invocation: Called by sp_manufacture_productionplaninfotrace / sp_manufacture_productionplaninfotrace1, Sp_Manufacture_ProductionPlanInfoTree_Base, Sp_Manufacture_ProductionPlanInfoTree_Base_TC — the production-plan tree-loading procedures that pluck specific filter clauses (e.g. bFilterName='tStartDate') out of the front-end's bFilter JSON before rebuilding the WHERE clause.
