- There are still WBS elements in the buffer ?The SAP error message CJ155 ("There are still WBS elements in the buffer") typically occurs in the context of project management and controlling when you are trying to perform certain operations on Work Breakdown Structure (WBS) elements. This error indicates that there are still WBS elements that are being held in the buffer, which can prevent certain actions from being completed.
Cause:
- Buffering Mechanism: SAP uses a buffering mechanism to improve performance. When WBS elements are being processed, they may be held in a buffer. If there are still elements in this buffer, it can lead to this error when you attempt to execute certain transactions.

- Inconsistent Data: Sometimes, inconsistencies in the data or incomplete updates can lead to this error.
Solution:
- Check for Open Transactions: Ensure that there are no open transactions or processes that are using the WBS elements. You can check for any ongoing processes that might be locking the WBS elements.
- Refresh the Buffer: You can refresh the buffer by using transaction code
