3754291 - Goods receipt runtime error (convt_overflow) due to currency conversion overflow from high material price

Symptom

  • Runtime error CONVT_OVERFLOW (CX_SY_CONVERSION_OVERFLOW) occurs during procurement processing.
  • DBSQL_SQL_INTERNAL_DB_ERROR triggered during document processing or analytical data access.
  • Currency or unit conversion errors observed in the system.
  • Error messages related to invalid conversion rate or value overflow are displayed.
  • Overflow occurs while converting large numeric values during processing.

Environment

SAP S/4HANA Cloud Public Edition

Reproducing the Issue

  1. Post a goods receipt for a purchase order item in the goods movement application.
  2. The system terminates with runtime error CONVT_OVERFLOW (CX_SY_CONVERSION_OVERFLOW). In some analytical scenarios, DBSQL_SQL_INTERNAL_DB_ERROR appears with a currency/unit conversion message.

Cause

  • A very high material price maintained per 1 base unit leads to an excessively large amount during currency conversion (for example, converting between currencies on the posting date), which exceeds numeric limits and causes CX_SY_CONVERSION_OVERFLOW.
  • In analytical views, missing or invalid exchange rates for the involved currencies and date can cause DBSQL_SQL_INTERNAL_DB_ERROR with a currency/unit conversion error.

Resolution

1. Review the material master price:

  • Check the price maintained for the base unit.
  • If the price per 1 unit is unrealistically high, correct it to a realistic value or maintain it for an appropriate base quantity to avoid extremely large converted amounts.
  • Repost the goods receipt after the price correction.

2. Verify currency conversion settings (for analytical errors):

  • Ensure valid exchange rates exist for the involved currencies on the relevant posting date.
  • Update or maintain the missing rates, then re-execute the analytical report.
