Linking a Search Help with a Screen Field

A search help can be assigned to a screen field as follows:

The search help is offered in all the screen fields where the table field appears. For this type of link, the search help parameters and the fields of the table or structure must be assigned to each other. This assignment causes a value transport between the search help parameters and their assigned fields when the input help is called.

Not all the parameters of the search help have to be assigned to a table field. You can leave the assignment open. A constant or any other field which is searched for in the module pool when the F4 help is called can also be assigned to a search help parameter.

The search help is offered for all the fields to be checked against this table. You must also define an assignment between the search help parameters and table fields here.

The search help is offered for all the table fields which refer to the data element.

The search help link is part of the definition of the object (table/structure or data element) to which the search help was linked. How to link a search help to a table field or table is described in:

Creating Fields in the Table

Linking a search help to a data element is described in:

Creating Data Elements

Hierarchy of the Search Help Call:

Conflicts could arise due to the three different ways of linking search helps. For example, search help A can be assigned to a field, search help B to the check table for the field and search help C to the data element.

Such conflicts can be solved by defining a hierarchy for the assigned search helps. First an attempt is made to call the search help of the table field. If none exists, the input help of the check table is used (if it exists). Two cases must be distinguished here. If the check table has a search help, it is displayed. Otherwise only the key values of the check table are displayed (if a Text Table exists for the check table, the text is inserted in the logon language). If there is no check table, the search help is called from the data element.
