SAP Error Message - Details

• Message type: E = Error

• Message class: OQ - IS-Oil : Message pool Service Station Retailing

• Message number: 451

• Message text: Table OIRADBT is INCONSISTENT: Duplicate records detected !

What causes this issue?

The SSR Document Base Table (DBT) was initially delivered with one key
field too much by mistake. This did not cause any major application
error in the past - however still it is a design error.
With the 4.6c CRT 14 this is corrected by moving field PBLNR out of the
key.
This report checks all the existing entries in the table to secure that
no duplicate records exist for the reduced key.
However by an unforseen application error there are such duplicate
records !
The entry for which duplicate records are detected are:
Client (Field MANDT) &V1&
Link number (Field LINKNR) &V2&
Item link number (Field ITLINKNR) &V3&
Link year (Field LINKYEAR) &V4&

System Response

to the SAP support organization via OSS.

  Data Entry Errors: Duplicate records may arise from manual data entry errors where the same record is entered multiple times.
  Data Migration Issues: If data has been migrated from another system, duplicates may have been introduced during the migration process.
