-
Materialize each form's L2 neighbors (upstream/downstream documents) and L3 neighbors (referenced entity tables) so the retriever can expand a vector-recalled form-card into a subgraph context via a single JOIN. 702 forms have downstream, 476 upstream, 1467 reference entity tables.
-
Map 业务中文名 -> real column -> table (38342 mappings, 6075 terms, 539 tables), ranked by form-usage for same-name disambiguation, with FK target (sFkTable/sFkKey) attached from viw_kg_edge_ref so NL2SQL knows the join. This is the field-dictionary half of the GraphRAG package.
-
Assemble one structured, embeddable text card per form (1748) merging node metadata, upstream/downstream document names, and the field 中文名 list. export_form_cards.sh emits JSONL for vector-store ingestion (group_concat_max_len raised to avoid truncating 269-field forms). Generated corpus is gitignored — regenerate deterministically via script.
-
Parse gdsconfigformslave.sRelation (comma-separated field&table&pk&display hops) into FK edges: src_table.field -> tgt_table.pk, with the set of display columns each FK surfaces aggregated per edge. 1597 distinct FK edges / 368 source tables / 109 target tables (mostly ele*/sis* master data). Provides the join dictionary for NL2SQL grounding.
-
One row per useful form enriched with business domain (L1, derived from normalized data-source prefix + AI-scene override), data source/exec type, and upstream/downstream flow counts from viw_kg_edge_flow. 857 forms participate in document flow; 63 back an AI tool; 92% domain-classified.
-
Materialize source-form -->generate--> target-form flow edges from the low-code config. Resolves BtnCopyTo.<Action>.sActiveId to the target gdsmodule exactly as Sp_Ai_AddCommonAfterNew does (sActiveId is the real target; the .ActXxx suffix is only a label). 411 distinct edges / 405 (src,tgt) pairs / 51 self-loops; 404 endpoints hit viw_ai_useful_forms. Captures full order-to-cash and procure-to-pay chains plus cross-domain (order->workorder, quote->process-card).
