Internal Office and Employee Services for Centralized Treasury Payment and Reimbursement Audit: Document Parsing and Chunking

Internal Office and Employee Services for Centralized Treasury Payment and Reimbursement Audit: Document Parsing and Chunking

What data for this category looks like

Data for this category comes from centralized treasury payment systems, unified budget management systems, electronic invoice platforms, and contract management systems. The update frequency is daily. Commonly processed documents include payment applications, fund use plans, invoices, contracts, acceptance documents, reimbursement approval forms, and payment vouchers. Individual documents often contain structured fields such as budget indicator codes, economic classification codes, payment amounts, approval workflow nodes, and acceptance numbers. Some contract documents include multi-page attachments and signature and seal information.

Data sources for this category involve multiple integrated systems. Commonly processed documents include structured forms and unstructured attachments. Multiple related documents must be processed in batch every day. Core structured fields such as budget indicator codes and economic classification codes must be extracted accurately, and they must not be accidentally truncated during chunking. Related documents such as invoices and reimbursement approval forms corresponding to a single payment must retain contextual association. The chunking logic must avoid splitting cross-document related information. Some contract documents have large file sizes. The parsing and chunking link must adapt to large file processing limits to prevent content loss or parsing timeouts.

Configuration Settings

Reference only; verify against the target FastGPT release and deployment documentation.

Configuration ItemRecommended SettingRationale
chunkSize800–1200 charactersCore fields for this category are mostly short text. The chunk length is matched to the contextual association length of fields such as budget indicators and payment amounts in documents, to avoid truncating critical information
chunkSplitterUse document built-in separators + semantic segmentationDaily documents include structured forms and unstructured attachments. Splitting by built-in separators preserves the integrity of form fields, and semantic segmentation is used to supplement related content
customPdfParseEnabledSome contracts and acceptance documents are in PDF format. Enabling custom parsing accurately extracts structured fields from signatures, seals, and tables, avoiding field misalignment caused by standard parsing
PARSE_FILE_TIMEOUT_SECONDS600 secondsLarge contract documents take longer to parse. This duration covers the parsing needs of most individual documents, preventing timeout errors
UPLOAD_FILE_MAX_SIZE100 MBMost individual batch documents for this category do not exceed this size. Documents beyond this range must be split before uploading to adapt to system parsing capabilities
chunkSettingModeManual configurationDocument formats for this category vary widely. Manual configuration allows flexible adjustment of chunking rules to adapt to different types of fiscal business documents

Three common misconfigurations

  • Symptom: When uploading contract PDF documents larger than 10 MB, the interface displays the timeout of 360000ms exceeded error. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter was not adjusted to a duration suitable for large file parsing. The default timeout setting is insufficient to cover the parsing time of this type of document.
  • Symptom: For some docx reimbursement approval forms with complex nested tables, table fields are empty or misaligned after parsing. Cause: The customPdfParse configuration was not enabled. The standard parsing engine cannot adapt to the nested table structure of fiscal documents.
  • Symptom: When the segment length after splitting by built-in separators exceeds the chunkSize setting, automatic truncation is not triggered, resulting in chunk content exceeding system thresholds. Cause: The automatic truncation logic under chunkSettingMode was not enabled. Only splitting by separators was done, without handling overly long segments.

How to confirm proper configuration

  • Upload a single typical document, such as a reimbursement approval form, and check the parsed chunk results to verify that core fields are fully retained.
  • Adjust the chunkSize parameter, then upload a large contract document to confirm that the parsing process does not trigger timeout errors.
  • Upload multiple related documents, such as an invoice and a reimbursement approval form, to check if the chunk results retain contextual association between documents.
  • Check system logs to confirm that parsing task durations do not exceed the PARSE_FILE_TIMEOUT_SECONDS setting.
