Types of Help Request:

  1. Automatic Help (F1) from Data Element

    • Comes from documentation maintained in the data element.

    • No coding needed — just maintain the documentation in SE11.

  2. Custom Help Request (Manual)

    • In module pool programs, you can write custom F1 help logic using PROCESS ON HELP-REQUEST.

Types of Value Help:
Automatic Value Help

Provided by the data element (via domain fixed values or check tables).

No coding needed.

Search Help (SE11)

Defined in Data Dictionary.

Can be reused across fields.

Manual/Programmatic Value Help

Custom logic using PROCESS ON VALUE-REQUEST and function modules like F4IF_INT_TABLE_VALUE_REQUEST.

Used when standard or search help is not enough.
