Hidden command handlers:

• Are used to perform non-visual tasks.

• VLF-WIN applications must use VF_AC020 as their ancestor.

• VLF-ONE applications must use VF_AC010O as their ancestor, the same as visible command handlers.

• May serve multiple purposes. The shipped DF_DET46 (VLF-WIN) and DF_DET46O (VLF-ONE) are useful examples of multi-purpose hidden command handlers.   

• Must have this option set in their definition:

 When using hidden command handlers it is important to remember they:

• Should always have the Default Command option set to NEVER for instance level commands or NO for business object level commands.

• Should never be used with the Hide All Other Command Tabs option set.

• Should never be attached to RAMP Destination screens.

• Should not attempt to display information to the user or interact with the user.
