Inspection and Process Record Audit for Warehousing, Lot Tracking, and In-Plant Logistics: Workflow Orchestration

This category of data typically comes from ERP/WMS systems, barcode or RFID devices, procurement and work order ledgers, warehouse location management

What the data for this category looks like

This category of data typically comes from ERP/WMS systems, barcode or RFID devices, procurement and work order ledgers, warehouse location management modules, AGV or conveyor systems, and weighing equipment. Daily generated documents include receiving slips, putaway slips, material picking and returning slips, inventory transfer slips, inventory count sheets, lot ledgers, first-in first-out (FIFO) and expiration date records. Data update frequencies are divided into three types: real-time (such as AGV position, real-time weighing data), daily (such as material picking and returning records), and monthly inventory (such as inventory book vs. physical count data). Core fields include material code, lot number, warehouse location number, expiration date, quantity, and inspection status. Common units are pieces, kilograms, cubic meters, and similar units.

The requirement for multi-source data access means workflows must support integration with different types of data source nodes, to prevent verification errors caused by data synchronization delays. Data sources with varying update frequencies need to align with appropriate trigger timing. For example, real-time data must trigger an audit immediately after an action finishes, while monthly inventory data can use a fixed cycle trigger. The variety of core fields for this category requires workflows to define configurable verification parameters via variables, to ensure key items like material identity, lot number, and expiration date are covered during audits. Cross-process material flow management requires workflows to connect multiple stages including receiving, putaway, and distribution, to enable full-process record traceability.

How to set up the configuration

The following configuration items apply to FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale for This Setting
variablesDefine material code, lot number, warehouse location number, and expiration date as required verification variablesMatch the core fields of category documents to ensure complete key parameters during audits
Trigger node delay10-30 secondsAdapt to the synchronization rhythm of real-time data, avoid reading data sources that have not completed updates
Exception branch triggerTrigger work order alerts and inventory book vs. physical difference records when nodeId returns a verification failureCorrespond to the consequences of errors in this category, enable process interruption and traceable exception handling
Environment variable invocationBind the ERP interface key and WMS access address configured during deploymentReuse custom deployment configurations, avoid hardcoding sensitive information
File stream processingConfigure to receive barcode image streams and call built-in OCR parsingAdapt to the barcode/RFID data source of this category, automatically extract material identification fields

Three common configuration mistakes

  • A "required field is empty" error occurs during workflow runtime, and non-essential verification links cannot be skipped. The cause is failing to distinguish between required and optional fields in the variables configuration, and enforcing verification on non-core fields generated temporarily.
  • When calling an external interface that returns an image stream, the workflow node cannot associate the parsing result with the lot variable. The cause is failing to configure the output binding rules for the file stream node, and failing to map OCR recognition results to preset variables parameters.
  • The workflow cannot read custom environment variables set during deployment. The cause is failing to enable environment variable invocation permissions in the node configuration, or the variable name spelling does not match the deployment configuration.

How to confirm the configuration is correct

  • Trigger a simulated receiving action, check whether the workflow verifies core fields such as material code and lot number according to the configured variables.
  • Manually pass a test barcode image stream, confirm whether the OCR parsing result automatically fills into the corresponding lot variable.
  • View the workflow runtime logs, confirm whether the values of custom environment variables match the deployment configuration.
  • Trigger a test scenario where verification fails, confirm whether the exception branch correctly triggers alerts and inventory book vs. physical difference records.
