• Message text: Multiple entries found with NCUMTIM 'unlimited'; compression not possible

What causes this issue?

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

The time dimension contains multiple entries for which the time
reference characteristic (NCUMTIM) is set to 'unlimited'.
The value 'unlimited' is the maximum possible value for the time
reference characteristic. This value is reserved for markers in non
-cumulative InfoCubes and cannot be used for standard transaction
records.

System Response

Compression is terminated.

How to fix this error?

Contact your system administrator.

Procedure for System Administrators

To allow compression to be carried out, the entries must first be
removed from the InfoCube.
To do this, you can proceed as follows:
Delete all packages that contain records in which the time reference
characteristic has the value 'unlimited'. You can identify these
packages by using transaction LISTCUBE.
Reload these packages and create a rule in the transformation that maps
the value 'unlimited' to a year before 9000.
Using transaction RSRV, then delete all entries that are no longer used
from the time dimension.
The InfoCube can be compressed again.

• What is the cause and solution for SAP error message DBMAN380 - Multiple entries found with NCUMTIM 'unlimited'; compression not possible ?

  The SAP error message DBMAN380 indicates that there are multiple entries found with the NCUMTIM (Next Cumulative Time) set to 'unlimited', which prevents the system from performing data compression. This typically occurs in the context of database management and data archiving processes.
  Cause:
  
  Multiple Entries: The error arises when there are multiple records in the database that have the same NCUMTIM value set to 'unlimited'. This situation can occur due to incorrect data entries or configuration issues in the database.
  Data Integrity Issues: It may also indicate a problem with data integrity, where the system is unable to determine which entry should be used for compression.
  Configuration Settings: The settings related to data archiving or compression may not be properly configured, leading to conflicts.
  
  Solution:
  To resolve the DBMAN380 error, you can follow these steps:
  
  
  Identify Duplicate Entries:

  Review and Correct Data:
  
  Analyze the identified entries to determine why they are marked as 'unlimited'.
  If necessary, update the records to ensure that only one entry has the NCUMTIM set to 'unlimited', or adjust the values to allow for proper compression.
  
  
  
  Check Configuration:
  
  Review the configuration settings related to data archiving and compression in your SAP system.
  Ensure that the settings are aligned with best practices and that there are no conflicting configurations.
