E$ Table in SQL Server - creating issues

Question

Hi All,
After a successful run of an ETL SCD Type2, the E$ table is craeted in the SQL Server but it is not deleted after the run even when it is successful, the second time I run it it causes a failure because of that, how do I automatically delete it after a succesful run, I understand the error table being there after a failure, so we investigate teh cause and then manually delete it. IS tehre a way to automatically delete it after a successful run.
Thanks for your time and help.

Hi,
When you say deleted", do you mean :
- DROPPED (= destructed, a droped table doesn't existe anymore)
- DATA DELETED (= the table is still here but the records are deleted)
By default, the CKM doesn't *drop* the error table. You can activate the "drop error table" option in the "control" tab of your interface. If so, the E$ table will be dropped (=destructed) at the BEGINNING of the interface. The E$ table is NEVER droped at the end of an interface (otherwise, we couldn't be able to read the errors).
But it shouldn't generate crash during the step "create error table" because the flag "ignore errors" is supposed to be true in the CKM step.
And, the CKM ALWAYS delete the errors of your E$ table at the beginning of the interface. It means the errors that were rejected and stored in E$ during the last execution are deleted (... in fact, only the errors due to this interface).
