What the documents look like
For document comparison in General export declarations, this page examines FastGPT document chunking. Invoice-addressee confirmation and a separate receiving contact require distinct identity roles. The examples are hypothetical.
Constraints at the document chunking step
A proposed export clause says the invoice addressee follows buyer confirmation and a receiving contact may be listed separately. An attachment has separate addressee-information and receipt-contact columns, using generic role names without real personal data. Different wording in these columns first requires a role check, not a declaration of conflicting transaction parties. If parsing removes column labels and leaves only two names, the essential relationship is lost. Before chunking, preserve the role each name serves in the document rather than comparing isolated text values as equivalent identities.
Configuration and implementation checks
| Original or chunk check | Specific source relationship | Evidence action |
|---|---|---|
| Column labels | Addressee and receipt contact | Check parsing preserves roles. |
| Confirmation qualification | Addressee follows buyer confirmation | Keep condition with addressee clause. |
| Separate listing | Contact may be separately listed | Do not infer conflict from different names. |
| Index trace | Addressee and contact entries | Check distinct targeted originals. |
| Attachment update | New column roles and confirmation content | Inspect processing and same-question citations. |
Documented conditions
| Documented item / implementation check | Condition |
|---|---|
Original-document check | Compare original files with parsed output. |
Chunk completeness | Keep conditions traceable to their subjects. |
Data and indexes | Retain original-data and index evidence separately. |
Sample retrieval | Retest literal wording and natural questions. |
Post-update check | Inspect training or index state after updates. |
Three common errors
One common error assigns the receiving contact to the invoice-addressee block and the answer suggests replacing the addressee. Another separates buyer confirmation from the addressee clause, turning a draft value into a confirmed identity. Compare original columns, parsed order and block conditions to locate role mismatch and lost confirmation scope separately. Indexes can offer addressee and contact search entries, but each should trace to the proper original data. A search label cannot establish party identity or replace the actual buyer-confirmation material needed for that field.
How to verify the setup
Acceptance should query exact addressee and receipt-contact wording, then ask whether the columns must contain the same name. Inspect returned blocks for complete roles and conditions. The answer can identify that a separate contact is permitted by the supplied wording while retaining addressee confirmation as a distinct check, without deciding party qualifications. After attachment revisions, inspect actual processing and indexes against the new version before repeating the questions. Upload establishes submission only, not repaired old column relationships or actual answer use of the updated confirmation material.
