DBIF_RSQL_SQL_ERROR CX_SY_OPEN_SQL_DB

Hi there.

We are on ERP ECC6.0 EHP3 with SAP MaxDB database.

We are getting the following error during using the DART ta code FTWH

( SQL error in the database when accessing a table.)

DBIF_RSQL_SQL_ERROR

CX_SY_OPEN_SQL_DB

How to correct the error

    Database error text........: "Illegal schema modification, parameters/column

     have changed type/number incompatibly"

    Internal call code.........: "[RSQL/INSR/TXW_VS400_0001 ]"

    Please check the entries in the system log (Transaction SM21).

    If the error occures in a non-modified SAP program, you may be able to

    find an interim solution in an SAP Note.

    If you have access to SAP Notes, carry out a search with the following

    keywords:

    "DBIF_RSQL_SQL_ERROR" "CX_SY_OPEN_SQL_DB"

    "%_T00BIK" or "%_T00BIK"

    "INSERT_DB_A001"

    If you cannot solve the problem yourself and want to send an error

    notification to SAP, include the following information:

    1. The description of the current problem (short dump)

       To save the description, choose "System->List->Save->Local File

    (Unconverted)".

    2. Corresponding system log

       Display the system log by calling transaction SM21.

       Restrict the time interval to 10 minutes before and five minutes

    after the short dump. Then choose "System->List->Save->Local File

    (Unconverted)".

Sorry, but i didnt find somethings related to "%_T00BIK" or "%_T00BIK" in SMP or xquery with  "INSERT_DB_A001"

SAP SMP delivers in the search now ( Abbruchsart: RABAX_STATE )

How could we solve the error? Maybe its an auth. error, i try that to eleminate this morning.
