Hi,

As SAP recommends, do not create/declare internal tables with header line. Create an explicit work area for internal tables and read into the work area or use field symbols (ASSIGNING).

Also, when performing READ command on internal table, use BINARY SEARCH. However, precaution, always sort the internal table with the fields used for read in WITH KEY clause.

Cheers.

1. Try using Internal tables without header line.

2. For work areas, define a separate one or use field symbols.

3. Try to use READ TABLE... BINARY SEARCH.

Hope this helps.

Thanks,
