Hi,
Nothing will happen! i guess just adjusting the RDBMS will take time!
In general the below steps needs to be performed! If no error find in adjustment even transports all will move without errors
In general what happens in SAP( inside) if you adjust the SE14:
- Table (TAB) is locked. All the views that used table TAB are deleted
- TAB is renamed as QCMTAB in database
- TAB is activated in ABAP Dictionary with new definition. Activation of modified table TAB leads to creation of database table QCM8TAB in database with primary key but no data.
- Reload data - data copied from QCMTAB to QCM8TAB (with MOVE-CORRESPONDING statement). Database commit is stored after 16MB. If a field length is reduced then field contents are truncated.
- Delete QCMTAB table
- Rename QCMTAB to TAB. Secondary indexes are newly created and views deleted in Step 1 are re-created
- Remove Lock from TAB
