SAP Error Message - Details

• Message type: E = Error

• Message class: KS - RK-S Master Data Maintenance

• Message number: 135

• Message text: ALE is active; check consistency of the data

What causes this issue?

You want to delete master data, and ALE is active for the selected
controlling area &v1&.
You cannot fully check the dependent data in the sender system, as -
depending on the distribution method - dependent data can be managed
locally. Also, when you transport all data into the central system, it
may happen that dependent data has not arrived yet so that the check of
dependent data might be incomplete.

System Response

Master data is deleted in the current system, even at the risk of
inconsistencies.
Master data is not deleted in the receiver system. Deletions can
currently not be transported.

How to fix this error?

Ensure the consistency of data by only deleting master data if no
dependent data exists in any system.
Delete the master data manually in each system.
