What are the disadvantages of defining a table with a very much higher data class and size category .

All have size category 0, but because of the contents, they should have 2 or 3. Can we just put 9 and forget about it? how much space will be reserved in the database for those over defined tables? that could be wasted...

The F1 help for data class provides information on how to select the proper value for the table.

Hi,

Some minimum space has to allocated to a table when it is created.. when the tables extends this space more space is allocated to it.. so it is better to allocate smaller sizes to tables than wasting space allocated to tables which will hold smal data,,

at the same time when the place is extended for more data then this data will not be allocated adjescent to the table space used currently.. hence this affects performance..

This is why it is useful to choose the appropriate size category..
