Add a field in search help

Question

Hi
I'm working in EBP system. I want to add a field in the cost center matchcode. This matchcode is situated in R3. This search help is KOSTN. The field a want to add is the information "blocked" to know if the cost center is blocked or not. This field doesn't belong to any table, it needs a block of instructions. I don't know how to do that, somebody told me i have to use a search help exit to do that. I don't know how it works... Does anybody can help me?
Thank you very much.

Hi,
I assume you have two issues here. How to select/filter with a static value of block_flag; and, how to let user enter (checkbox) a value for this filter.
For the first, you can code your logic in the
<i>if callcontrol-step = 'DISP'</i> block.
Here, you need to read all records from record_tab for the key values (kostl, kokrs, bukrs...). For this, you will need to use another itab like this:
<i>data: begin of  results_tab occurs 1,
          kostl like ...,
          kokrs like ...,
        end of results_tab.</i>
Function F4UT_PARAMETER_VALUE_GET allows you to read records from record_tab (which has a text string row) into results_tab. Once you have called this, you can apply your select to check which records of this result set do not match your criteria. Ones that do not match, can be deleted from the records_tab (with index value as rows in results_tab match with corresponding rows in records_tab). <i> I am not sure whether you can read multiple fields from the record_tab at the same time. If not,you will need to call this function multiple times to read each key field (into separate internal tables) from the result set record_tab.
At the end of this, you should have a filtered records_tab showing a subset of the current F4 list.
For allowing user an option of additional field to choose, you will probably need to modify the search-help by adding additional fields. I am not too sure about it.
A template code can be seen in F4IF_SHLP_EXIT_EXAMPLE function.
