Remove the 'Do you want to save changes?' Messages in Forms

here is it ...

1. Modify the CLEAR_ALL_MASTER_DETAILS procedure body. Change the existing CLEAR_BLOCK(ASK_COMMIT) to CLEAR_BLOCK(DO_COMMIT).

2. Specifying NO_COMMIT or NO_VALIDATE with the CLEAR_BLOCK built-in causes

Oracle Forms to flush the current block without performing a commit or prompting the operator.

ex:CLEAR_BLOCK(NO_COMMIT,NO_VALIDATE);
