How To Fix CCMSBI_BCT_MESSAGES038 - Lock error: there may be duplicate data records

SAP Error Message - Details

• Message type: E = Error

• Message class: CCMSBI_BCT_MESSAGES -

• Message number: 038

• Message text: Lock error: there may be duplicate data records

What causes this issue?

During the transformation, old records are deleted to avoid duplicated
data records. An error occurred with the lock on the data required to do
this.

System Response

The old data is not deleted, however the new data is written, meaning
that there could be duplicated records. This has no effect on the
functioning of the system, however it does mean that the Info Provider
grows unnecessarily.

How to fix this error?

A reason for the failing of the lock is too little storage space for log
attributes in the CCMS. To verify this, check the memory in
<DS:TRAN.RZ20>CCMS</> </> in CCMS Selfmonitoring under MoniInfra_* (for
example, by double-clicking one of the subnodes). If this shows that the
memory for log attributes is used up, you can either delete attributes
that are no longer required, increase the storage space, or move the
monitoring context 'CCMS BI Reporting" to another server with sufficient
storage space.
