Quelle est la cause de ce problème?

A preceding change in the data model required an adjustment of change
requests that were not yet finalized.

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

This error occurred because <ZH>all</> of the following are true:
The data model was extended with attributes that are related to an
active area
The data model was activated
Open change requests relating to this data model existed in the
respective client
These open change requests have not yet been adjusted.
This situation can happen in the following scenarios:
The data model was extended and activated manually<(>,<)> and the open
change requests have not yet been adjusted.
One or more Switch BC Sets containing data model changes were activated.
If more than one of these BC Sets were activated during one process
(e.g. an activation of a business function)<(>,<)> this message will
appear as an error message in all activation logs starting from the
second BC Set involved.

Réponse du système

In the manual activation scenario (scenario 1 above)<(>,<)> this message
is displayed after pressing the <LS>Activation</> pushbutton and the
data model is not activated.
In the Switch BC Set activation scenario, the inactive version of the
data model was completely updated with the changes of all respective BC
Sets. However the active version of the data model was only updated with
the changes of the first activated BC Set.

Comment corriger cette erreur?

In order to adjust the open change requests, perform the following
steps:
1. Update SMT Mapping:
When new fields are added to a data model with a reuse active area, you
may first have to extend the mapping of the access class for the reuse
active area. You can use the <DS>
<DS:TRAN.SMT>Service Mapping Tool (SMT) to edit the mapping.</></>
2. Adjust BP Mappings:

If the data model BP or a custom data model that uses the same reuse
active area was enhanced, run the <DS>
<DS:TRAN.SMT>Service Mapping Tool (SMT) to adjust the mappings
BP_BP_CENTRL_2API and BP_BP_CENTRL_2STA.</></>

3. Adjust Open Change Requests:
Afterward, you need to adjust the change requests with regard to the
modified data model. This is done by using the program
USMD_ADJUST_STAGING. You can execute this program for a specific data
model by choosing the <ZK>Adjust Staging Area of Linked Change Requests
</> pushbutton in Customizing for Master Data Governance, Central
Governance under <ZK>General Settings</> -> <ZK>Data Modeling</> ->
<ZK>Edit Data Model</>. This ensures the program is executed in all
respective clients via batch jobs. If any issues occur, manually run the
program again in the respective clients.
4. Adapt changes from Switch BC Sets:
If multiple Switch BC Sets were activated, manually activate the data
model and repeat the steps 1 to 3.
The changes that are executed must also be executed in all target
systems linked to the transport of the data model change - <ZH>esp
ecially in live systems</>. Only then can you again create new change
requests in those target systems after the data model is changed. Before
those changes are executed, you also cannot make additional local
changes to the same data model.
