SAP Error Message - Details

• Message type: E = Error

• Message class: DMCLG - DMC Tool Development

• Message number: 272

• Message text: Fehler bei der Berechnung des Zugriffsplans

Was verursacht dieses Problem?

The access plan calculation for an initial load of a table failed.

Systemantwort

The system cancels the access plan calculation, sets the table status to
Failed, and does not transfer the data from the table to the target
system.

Wie behebe ich diesen Fehler?

Check the application logs to find other error messages explaining why
the calculation failed.
If you are using reading type 1, and you encounter messages that contain
statements such as "the block size limit is exceeded" or "a delimitation
is not possible", then chosen selection parameter is not sufficiently
selective. This means that the amount of data in one access plan portion
is too large. You can either use reading type 5, or choose a better
selection parameter. Afterwards, you have to delete and redefine the
migration object.
If you are using SAP LT Replication Server, you can use the performance
options in Advanced Replication Settings (transaction LTRS) to change
the reading type or the selection parameter. You can then use the
relevant processing steps in transaction LTRC to delete the old load and
replication objects.

Das System gibt eine Fehlermeldung aus und erlaubt Ihnen nicht, mit dieser Transaktion fortzufahren, bis der Fehler behoben ist.
