Hi,

When my user try to access BEx queries, he is getting the following pop up messages

<internal error> problem when writing table: C_T_VARIABLES

<internal error> problem when writing table: E_T_DIM

<internal error> problem when writing table: E_T_MEM

<internal error> problem when writing table: E_T_ATR

<internal error> problem when writing table: E_T_PRPTYS

<internal error> problem when writing table: C_T_HRY_TYPES

<internal error> problem when writing table: E_T_CEL

<internal error> problem when writing table: E_T_FAC

<internal error> problem when writing table: E_T_CON

<internal error> problem when writing table: E_T_DRILL

and then report is getting diplayed. and when user try to edit properties again same pop up messages are coming.

when I access queries from my machine those are working fine..

Can some one help me to solve this ?
