In SAP_BASIS 7.40 Data Dictionary is now supporting table´s field name up to 30 bytes length. In the past this value was only 16 bytes.
This modifications is being delivered in note 1680583 ( Field names for tables and views with more than 16 char ).
From development perspective this is really nice to have this flexibility to create objects where you can include more details about business meaning as part of field name. For sure this is helpful for new projects once the restriction now is up to 30 bytes per field.
So far this is possible to be used in SAP_BASIS 7.02, 7.31 and 7.40
