How To Fix GLPL503 - Posting cancelled by user due to different distribution keys

GLPL503 - Overview

• Message type: E = Error

• Message class: GLPL - Message class planning FI-SL/GL

• Message number: 503

• Message text: Posting cancelled by user due to different distribution keys

What causes this issue?

You cancelled the posting procedure. You used different distribution
keys for currencies or amounts, but per line, you can only save one
distribution key for the currencies and one distribution key for the
amounts. Thus, the period distribution of the current distribution key
is carried out, but the distribution key is set to "Distribution as
before".
Example
If distribution key "4" was used for the local currency and
distribution key "1" for the transaction currency, a corresponding
distribution is carried out to the periods for both currencies.
However, only one distribution key can be saved in the database. The
two aforementioned distribution keys are thus replaced by "2"
(Distribution as before). The local currency is thus stored with a
corresponding distribution key "4" and the transaction currency with a
corresponding distribution key "1", although the value "2" is contained
in the distribution key field.

System Response

The posting procedure is cancelled.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
