How To Fix USMD1A027 - Postprocessing of data model activation is not completed

SAP Error Message - Details

• Message type: E = Error

• Message class: USMD1A - Messages: Abstraction Layer

• Message number: 027

• Message text: Postprocessing of data model activation is not completed

What causes this issue?

The last activation of data model &V1& requires some postprocessing in
all clients that have open change requests. The postprocessing must be
manually scheduled as a background job following the activation. Before
this occurs, the access class for the reuse active area needs to be
updated so that the fields added to the data model are mapped to the
correct fields in the reuse active area. You can use the
<DS:TRAN.SMT>Service Mapping Tool (SMT)</> to edit the mapping.

If the data model BP or a custom data model that uses the same reuse
active area was enhanced, run the
<DS:TRAN.SMT>Service Mapping Tool (SMT)</> to adjust the mappings
BP_BP_CENTRL_2API and MDG_BS_BP_MAP_2STA.

The changes that are executed must also be executed in all target
systems linked to a transport of the data model change - <ZH>
particularly 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.
The reason why postprocessing is not yet completed can be as follows:
The background job is still running in the current client.
The background job was terminated because of a program error.

System Response

The system prevents the change or saving of master data in data model
&V1& until postprocessing has been completed.

How to fix this error?

Wait until postprocessing is complete or schedule the postprocessing if
this has not yet been done. You can automatically carry out the
scheduling of the report program in all relevant clients for a specific
data model by choosing the 'Adjust Staging Area of Linked Change
Requests' pushbutton in the Customizing activity 'Edit Data Model'.

Procedure for System Administrators

You can examine the status of the background job in transaction SM37.
The name of the job adheres to the following pattern:
USMD_ADJUST_STAGING_<client>_<data model>
If the job was terminated, you can directly execute the report program
USMD_ADJUST_STAGING for data model &V1&.
You can also analyze the application log with transaction SLG1. The
object is called FMDM and the subobject is called ADJUST_STAGING.

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