Choose a manageable sample from the actual systems, removing unnecessary personal information. Ask the owners to explain what each row represents and which reference is stable. Include an order split across several dispatches, one missing match and a corrected export. Those examples are more useful than a long list of desired dashboard fields.
Write down the import outcome before designing its summary. A received file, a reviewed batch and an applied change are separate moments. Decide what staff should see after each one and how they return to unfinished exceptions. If an import is interrupted, the implementation needs to establish what was accepted before anyone retries it.
For Delhi NCR–Ranchi reviews, bring the sales and dispatch owners into the same mapping conversation. Keep the agreed sample and decision notes for later checks. A focused first release can support one reliable reconciliation task; additional sources can follow once their identifiers, permissions and correction responsibilities are clear.
