STEP 1 OF 41. Preserve both inputsOpen Books (6 rows) and GSTR2B (5 rows). Supplier aliases are consistent across both tables and are not valid GSTINs. The workbook covers six distinct document keys.
STEP 2 OF 42. Inspect the exceptionsOpen Reconciliation. The sample uses INR 1 tolerance for each value/tax field. Duplicate records take priority; a duplicate must not be treated as a valid one-to-one match.
STEP 3 OF 43. Investigate one mismatchFor S02 / A002, taxable values differ by INR 1,000 and CGST and SGST each differ by INR 90. Prompt: Draft a supplier follow-up for A002 using only these differences; do not conclude ITC eligibility.
STEP 4 OF 44. Review before actionInvestigate duplicate source entries, portal-only records and missing supplier reporting separately. Use reviewed evidence to decide corrections; do not change records just to force a match.
