We create a simple search help YSH_ID_PERSON for the column ID_PERSON of the table YPERSON
Creating a simple search help
As can be seen at Data collection ! Selection method, we have used the table name YPERSON. This means that all the data required come from our table YPERSON. A search help can have the following parameters: “import parameters”, “export parameters” or “no import” and “no export”. We have used ID_PERSON as export parameter, because we want its value to be returned to the input template. LPos represents the parameter position in the hit list: FIRSTNAME has the position 1 and it is firstly displayed in the hit list, and LASTNAME has the position 2, being displayed after the FIRSTNAME.
Testing a search help
Afterwards, we want to use this search help in a Web Dynpro application. We create a search option for a competitor. The user has to enter the competitor’s ID into a search mask. The list of IDs is limited to the number of competitors. When the user doesn’t know the competitor’s ID, he uses the search help and can choose the competitor’s name. The content of the ID_PERSON parameter is returned to the search mask as soon as the user has selected a line of the hit list in the input help. In this way, we facilitate the input.
We can use this search help if we link it with the ID_PERSON column of the YPERSON table. To do this, we select the column ID_PERSON and press the button “Srch Help”.
Search Help for the field ID_PERSON
After we enter the search help name, we have to create the search help attachment, and to save and activate the table
How to create search help attachment to the column ID_PERSON
In this way, we have created a simple search help for the column ID_PERSON of the table YPERSON. When we use this column in Web Dynpro, the Framework creates a special icon to be used at the runtime to call the input help. Moreover, we can use the keyboard key F4 to call an input help.
To be able to access a search help from a WD component, the proper Input Help Mode context attribute property has to be set (“Automatic” or “Dictionary Search Help”).
