SAP Technical Settings

SAP Technical Settings

Once this has been saved, the next step is to move on to maintaining the technical settings of the Table. Before creating the final Database table, SAP will need some more information about the table being created.

Select 'Technical settings' via the toolbar above the table, through the 'Go to' menu, or with the shortcut CTRL+SHIFT+F9.

Here, it is important to tell the system what Data class is to be used, so select the drop down button. There are five different options, with accompanying descriptions. For this table, select the first, labelled 'APPL0', and double-click it:

For the 'Size category' field, again click the drop-down button. Here, you have to make an estimate as to the amount of data records which will be held within the table so that the system has some idea of how to create the tables in the underlying database. In this instance, it will be a relatively small amount of information, so select the first size category, labelled 0:

Below this are the Buffering options. Here, 'Buffering not allowed' should be selected:

This prevents the table contents from being loaded into memory for reading, stopping the table from being read in advance of the selection of the records in the program. You may, correctly, point out that it may be advantageous to hold the table in the memory for speed efficiency, but in this example, this is not necessary. If speed was an issue in a development, buffering would then be switched on, ensuring the data is read into memory. In the case of large tables which are accessed regularly but updated infrequently, this is the option to choose.

Nothing else on the 'Maintain Technical Settings' screen needs to be filled at this point, so click Save and then go back to the table itself. If all of this is successful, then the table should now be in a position to be activated and the entry of records can begin. Click the Activate icon to activate the table and check the status bar, which should again read 'Object Activated'.
