How To Fix GTR_FI155 - Reversal inconsistency regarding billing document &1

GTR_FI155 - Overview

• Message type: E = Error

• Message class: GTR_FI - Grantor Fi Integration

• Message number: 155

• Message text: Reversal inconsistency regarding billing document &1

What causes this issue?

When running GM-GTR invoicing, the system has to take account of the
reversed FI documents linked to GM-GTR billing document &V1&. The system
finds at least one FI document &V2& &V3& that is linked to GM-GTR
billing document &V1& and is reversed (timestamp &V4&).
However, other non-reversed FI documents created in the same invoicing
run as FI document &V2& also exist. This is an inconsistent financial
execution state because the adjustment behavior of the invoicing run
depends on the fact that all FI documents belonging to a specific GM-GTR
billing document are reversed, or none of them is.

System Response

The invoicing run is not possible.

How to fix this error?

Correct this inconsistency by reversing all FI documents belonging to
GM-GTR billing document &V1& runtime (timestamp &V4&). Check table
GTRFIBILLREL to find them.

Procedure for System Administrators
