Transaction log is growing in Simple mode

Hi All,

We have installed SAP EHP6 system on MS SQL 2008 R2, Since it was development system we have kept in simple mode.

But still we find the Transaction log is growing daily and cannot  truncate the log.

I found the  below reuse wait reason as Replication.

Recovery model          SIMPLE

Reuse wait reason       REPLICATION

Do we have DB setting as above as default  when we install MS SQL or any DB consultant has changed any parameter.

And also how can we remove Replication for Transaction Log.

Regards,

Kiran
