SAP Error Message - Details

• Message type: E = Error

• Message class: RSAN_RT - Messages for Runtime Analysis

• Message number: 639

• Message text: Double enregistrement lors de l'écriture des données ds table '&1'

Quelle est la cause de ce problème?

An analysis process does not take uniqueness of data records
into account when processing data according to any available
key fields. A database table, however, does consider uniqueness.
When writing data to table &V1& there may only be one data record for ea
characteristic combination of key fields. If another unique index is
available in the table, the data also has to be unique according to this
index.

Réponse du système

The analysis process terminates because not all of the data could be
written to table &V1&.

Comment corriger cette erreur?

Check and change the definition of the analysis process. Using a
suitable definition of the analysis process, ensure that duplicate
records do not arise during updating, for example:
Check whether all key fields are filled correctly in the field mapping
on the data flow arrow before the data target.
Insert an aggregation node in front of the data target and aggregate
the data to fit the key fields of the data target. Use the key fields
of the data target as grouping fields in the settings for the
aggregation nodes. Use all of the other fields as aggregation fields.
