What the documents look like
For product questions in Letter-of-credit documents, this page examines FastGPT workflow routing. Compare the material received with the sources used in the answer. The examples are hypothetical.
Constraints at the workflow routing step
A credit instrument and its supporting documents can locate how goods are described in a transaction, while a selection question still needs a precise target. A proposed input may contain the credit’s commodity passage, the invoice description and a note that manufacturer use instructions are absent. After form collection, compare all three received inputs. Matching document names must not become matching product performance, and wording in payment conditions cannot independently establish suitability.
Configuration and implementation checks
| Check | Proposed input for this page | Observed acceptance evidence |
|---|---|---|
| Question target | Commodity passage, invoice wording and intended-use question | Trade wording does not become performance evidence |
| Submission receipt | Two passages supplied; manufacturer guidance absent | The next step preserves all three input states |
| Model routes | Inspect documents or obtain model instructions | The actual recipient matches the selected source |
| Incorrect connection | An instructions request still reaches the old answer step | Inspect connections and retest selections and values |
| Business result | Actual presentation or procurement operation receipt | Assess it separately from product reading and conversational completion |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Form input node | Submitted form values pass to subsequent steps. |
User-selection node | Execution follows the connected selected branch. |
Interaction-state check | Inspect waiting and post-submission states. |
Output handoff check | Compare values passed between steps. |
External-operation responsibility | External business operations require an implementation. |
Three common errors
For a model-difference question, a source owner may choose to inspect the document passages or obtain manufacturer model guidance. Verify their receiving paths separately. Reading transaction documents supports only their actual statements, without supplying the technical evidence required by the other route. If a request for instructions still reaches the previous answer step, inspect the selection record and connections. A completed branch does not establish product correspondence while its source remains absent. Another failure occurs when manufacturer guidance has been supplied but downstream input still contains only the earlier invoice description. Compare the two submitted source lists against the material actually passed to the answer step, then inspect its citations. Retest after repairing that handoff; uploading the additional document does not establish that it participated in the selection explanation.
How to verify the setup
Retain the question, document versions and added instructions for the retest, checking that the answer distinguishes banking-document reading from product-source reading. Keep conditions absent from manufacturer guidance unresolved; bills of lading or insurance material do not replace that guidance. Updates to presentation documents, procurement material or external records need their actual interface, authorization and result. Ending this conversation does not establish bank acceptance or product acceptance.
