Using the Meta method, you can adjust any meta data of the search. For example, you can change the search bar to dropdown or activate and disable strict search.
Our Search BAdI blog series in overview |
The dropdown search suites best for short result lists and always loads all values locally first. Then, the search is executed on the locally loaded values. Thus, dropdown is ideal for short lists. On the other hand, the search function is executed for the entered search term only (eventually it is executed multiple times, if you enter the letters quite slowly). Therefore, SEARCH setting suites best for objects with large master data selections.
The filter contains the search type and the search name. For example, if the search is executed on an InfoObject, the search name is the name of the InfoObject.
The table or DSO is not part of the filter. It means the BAdI is executed across all DSOs or tables, which contain the same InfoObject. This way, you don’t have to implement a BAdI multiple times for different DSOs.
If you want to implement different searches for DSOs, which contain the same InfoObject, you can implement a new referenced InfoObject (so that the master data is reused). Moreover, you can also set table specific settings in the Table Column Properties. You can also use the Table Maintenance Meta BAdI to overwrite the settings done in the Search Meta BAdI.
This exit is implemented in BADI /NLY/BADI_SEARCH, via interface /NLY/IF_BADI_SEARCH, method SET_META_EXIT. It contains the parameters shown in the table below.
