errors when synchronise the INVENTTABLEMODULE

Hi 

I am getting some errors when i tried to synchronise the INVENTTABLEMODULE.

[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot drop the index 'INVENTTABLEMODULE._dta_index_INVENTTABLEMODULE_10_1642488930__K22_K20_1_2_3_4_5_6', because it does not exist or you do not have permission.
SQL-instructie: DROP INDEX INVENTTABLEMODULE._dta_index_INVENTTABLEMODULE_10_1642488930__K22_K20_1_2_3_4_5_6

Please any one can help to fix this issue. This is very urgent

Thanks in advance
