DBIF_RSQL_INVALID_REQUEST dump while deleting TMP Table

Dear All,

I am getting abap dump DBIF_RSQL_INVALID_REQUEST while I am trying to delete some tmp tables.

In ST22 the following messgae exists

'In a statement an invalid request was made to the database interface

when accessing table "ZITM_EMP ".'

This is happening for another table also.

Any solution for this?

Warm Regards

M
