GET_SIMPLE_HELPVALUES 
GET_SIMPLE_HELPVALUES
Use
Method GET_SIMPLE_HELPVALUES of the service object (RUNTIME->DDIC_UTILS) defines the list of values from a simple value help.
As import parameter you must declare a reference to the data object whose value help is used. This data object must have a direct or indirect reference to an elementary Dictionary type (data element or structure field) to which a simple value help (fixed values, check table, search help) is assigned. For example, the method can pass a reference to a data object that is associated with an elementary component of a Dictionary structure (DATA: var TYPE strucname-compname.) or a data object that directly is associated with a data reference (DATA: var TYPE dtelname.).
The method returns the values found in a two-column table. The KEY column contains the internal values, while the VALUE column contains the associated texts themselves. Parameter SORT_VALUES can be used to control whether and how the list of values should be sorted. For example, for a list of values with a number for the day and a name for the day of the week, sorting by VALUE column would give you the following order: Tuesday, Thursday, Friday, Wednesday, Monday, Saturday, Sunday. You should sort by the KEY column here. If the value help was defined with fixed values, these are often stored in the required order and you do not need to sort the values.
