  • Users see data in a friendly, understandable format (e.g., formatted dates, leading zeros removed).
  • System stores data in a standardized internal format (for consistency and integrity).

How It Works

When a domain is assigned a conversion routine:

  • At input (user to system): the routine converts external input to internal format.
  • At output (system to user): the routine converts internal format to user-friendly format.

Example

Domain: MATNR (Material Number)

  • Internally: Stored as 18 characters with leading zeros, e.g., 000000000000123456
  • Externally: Shown as 123456 to the user

Conversion routine: ALPHA

  • Input: Adds leading zeros to match the length
  • Output: Strips leading zeros for display
    Type Value
    External 123456
    Internal 000000000000123456

    How to Assign a Conversion Routine

    1. Go to SE11 → Choose your domain.

    2. In the conversion routine field, enter the routine (e.g., ALPHA, CONVERSION_EXIT_ALPHA_INPUT/OUTPUT).

    3. Save and activate.

    The actual logic resides in function modules:

    • CONVERSION_EXIT_YYYY_INPUT

    • CONVERSION_EXIT_YYYY_OUTPUT
