Dear Radhu,

Please checkout this sample program

DEMO_DYNPRO_MODIFY_SCREEN

++++

ACTIVE, INPUT, OUTPUT, and INVISIBLE

There are certain hierarchy rules between the components ACTIVE, INPUT, OUTPUT, and INVISIBLE. They also have different effects depending on their respective static settings.

The ACTIVE component has no equivalent in the element attributes. Instead, it changes the components INPUT, OUTPUT, and INVISIBLE.

At the beginning of the PBO, ACTIVE is always set to 1, regardless of the static attribute settings. Setting ACTIVE to 0 automatically sets INPUT = 0, OUTPUT = 0, and INVISIBLE = 1. Any other changes to the settings of INPUT; OUTPUT, and INVISIBLE for the same table line are ignored. Conversely, setting INPUT = 0, OUTPUT = 0, and INVISIBLE = 1 sets ACTIVE to 0, and any further assignment to ACTIVE for the same table line will also be ignored. The setting ACTIVE = 1 has no other effect on the attributes. The only purpose of the ACTIVE component is to allow you to make a screen field inactive through a single assignment. You should particularly note that a module call linked to a FIELD statement in the screen flow logic is always executed, even when SCREEN-ACTIVE = 0 for the field in question. If you want to prevent a module from being processed for an inactive field, you must specify the FIELD and MODULE statements separately.

REQUIRED

When you set REQUIRED = 1, a field that is ready for input is made mandatory. Users can only leave the screen when all mandatory fields contain an entry. Exception: Function codes with type E and modules with the AT EXIT-COMMAND addition.
