What causes this issue?

Succeeding WIP batches exist for the selected WIP batch (e.g. as a
result of splitting the WIP batch). It is therefore no longer at the
highest level.
However, you can only delete WIP batches of the highest level.

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

System Response

The system does not delete the WIP batch.

How to fix this error?

If you want to delete the selected WIP batch, you must first delete all
follow-on WIP batches and copies of this WIP batch.
If, in turn, successors or copies of these WIP batches exist, you must
also delete these.

COWIPB147 - Details

• The SAP error message COWIPB147 indicates that a Work in Progress (WIP) batch cannot be deleted because it is not at the highest level in the production order hierarchy. This typically occurs in the context of production orders and WIP accounting, where certain conditions must be met for a batch to be deleted.
  
  Cause:
  
  Batch Hierarchy: The batch you are trying to delete is part of a hierarchy where there are other dependent batches or components that are at a higher level. In SAP, WIP batches are often structured in a parent-child relationship, and you can only delete a batch if it is at the highest level (i.e., it has no dependent batches).
  Open Production Orders: If there are open production orders that reference the WIP batch, it cannot be deleted.
  Accounting Entries: If there are accounting entries related to the WIP batch, it may prevent deletion.
  
  
  Solution:
  
  Check Batch Hierarchy: Use transaction codes like CO03
