How To Fix RSO_RES_ADSO161 - &1 must be remodeled during activation if DSO is not empty

SAP Error Message - Details

• Message type: E = Error

• Message class: RSO_RES_ADSO - Datastore Object

• Message number: 161

• Message text: &1 must be remodeled during activation if DSO is not empty

What causes this issue?

If the DataStore object contains data, remodeling will be necessary
after activation of the DataStore object with the current settings.
If the DataStore object is empty, activation will be possible without
the need for remodeling.
Remodeling (in the target system) will also be needed if the DataStore
object can be activated in the current system (because the object is
empty here), but the changes are transported to a system where the
DataStore object is not empty.
More details about why remodeling is necessary can be found in other
messages.

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

  The SAP error message RSO_RES_ADSO161 indicates that a DataStore Object (DSO) must be remodeled during activation because it is not empty. This typically occurs when you are trying to activate a new version of an ADSO (Advanced DataStore Object) that has existing data in it. The system requires a remodeling process to ensure that the existing data is compatible with the new structure or changes being applied.
  Cause:
  
  Existing Data: The DSO has existing data that may not conform to the new structure or changes being introduced.
  Changes in Structure: Changes in the ADSO structure (like adding/removing fields, changing data types, etc.) necessitate a remodeling process to ensure data integrity.
  Activation Process: The activation process checks for data consistency and compatibility with the new model, leading to this error if it finds discrepancies.
  
  Solution:
  To resolve this error, you need to perform the following steps:
  
  
  Remodel the ADSO:

  If necessary, you may need to delete or archive the existing data if it is not needed.
  
  
  
  Re-activate the ADSO:
  
  After remodeling, try to activate the ADSO again to see if the error persists.
  
  
  
  Review Changes:
  
  Review the changes made to the ADSO structure to ensure they are necessary and correctly implemented.
