    Context information from the processed input template (screen) can be copied to the help process with an import parameter. Where an import parameter gets its values from is defined when the search help is attached to the corresponding field of the input template.

    Values can be returned from the hit list to the input template (screen) with an export parameter. The fields of the input template in which the contents of the export parameter are returned are defined by the search help attachment.

    if helpful reward some points.

    <b>Import and Export Parameters</b>

    When an input help is called, the entries that the user already made in

    the input template are taken into consideration. For example, if a user calls the input help for the flight number and already specified the carrier, of course only the numbers of flights of this carrier should be offered.

    On the other hand, if the user selects one row of the hit list, more than one field of the input template might have to be filled with data from the selected row of the hit list. For example, if the flight number is obtained from the hit list, the city of departure and the destination should also be returned in the screen template.

    The interface of a search help defines the context data that can be used in the input help and the data that can be returned in the input template.

    A parameter of a search help can be classified as:

    Import parameters:

    Parameters with which context information from the processed input template (screen) may be copied to the help process.

    Export parameters:

    Parameters with which values from the hit list may be returned to the input template.

    A parameter can simultaneously be an input and an export parameter. A search help can also contain parameters that are neither import nor export parameters. Such parameters could be required for the internal input help process, for example.

    When you attach a search help, you must define where the import parameters of the search help get their values from and the fields in which the contents of the export parameters are returned.

    Hi

    <b>IMPORT Parameters for Search Help</b>

    Flag if the parameter is an import parameter.

    Context information from the processed input template (screen) can be copied to the help process with an import parameter. Where an import parameter gets its values from is defined when the search help is attached to the corresponding field of the input template.

    <b>EXPORT Parameters for Search Help</b>Flag if the parameter is an export parameter.

    Values can be returned from the hit list to the input template (screen) with an export parameter. The fields of the input template in which the contents of the export parameter are returned are defined by the search help attachment.

    IMPORT Parameters

    IMPORT parameters correspond to the formal input parameters of subroutines. They pass data from the calling program to the Function Module.

    EXPORT Parameters

    EXPORT parameters correspond to the fonmal input parameters of subroutines. They pass data from the Function Module back to the calling program (which is not possible in subroutines).

    Table Parameters

    Table parameters are internal tables. Internal tables are treated like changing parameters and re always passed by reference.

    Source Code:

    The ABAP/4 Editor screen displays the ABAP/4 source code of the function module.

    <b>Import Parameters, Changing Parameters and table parameters can be optional. This means that your can omit the corresponding actual parameter when you call the function in the claling program. If the parameter is optional and the actual parameter is not specified, you can speicy a default value for use in the function module. Export parameters are always optional.</b>

    rewards if useful.
