Hi,

Please do an analysis, if it is really required to fill multiple tables, and then murge them, an alternate to this can be, to maintain a single internal table with all the fields and go on filling the same table at multiple locations of your program.

If it is required to merge multiple internal tables into one, then keep the following points in mind:

  1. Avoid loop inside loop. This can be acieved by using read statements. If reading a single record at a time does not solve the purpose, then you may use parallel cursors.
  2. Instead of modifying the interal table data using MODIFY statement, use Field symbols.

Hope it helps. Thank you.

Regards,
