Search Help Record_Tab Enable Multiple Selection CV04N

Former Member — Tue, 03 Apr 2018 17:07:22 GMT

Transaction Code: CV04N

Go to Object Links tab > Vendor > press F4

It will display search help KRED_C (then KRED_T). Elementary search help KREDI (Vendors by Country/Company Code) only allows one selection. My requirement is to enable multiple selection.

What I did was copied KREDI to ZKREDI and enabled the multiple selection feature (callcontrol-multisel = 'X') in the search help exit. Checkbox is now present to select multiple values. RECORD_TAB now shows the records selected depending on how much boxes were ticked. However, only the last record is being displayed.

In the screenshot, I selected 5 records. However, only the last record will be displayed in the left table control "Vendor"

Search Help Exit Pseudo Code

CHECK sy-tcode EQ 'CV04N'.

*EXIT immediately, if you do not want to handle this step

IF callcontrol-step <> 'SELONE' AND

callcontrol-step <> 'SELECT' AND

callcontrol-step <> 'RETURN' AND

callcontrol-step <> 'DISP'.

EXIT.

ENDIF.

"Enable multiple selection

callcontrol-multisel = 'X'.

IF callcontrol-step = 'RETURN'.

ENDIF.

Problem:

How can I return multiple selected values in the screen?

hi,

for filling selected data of search help in table control, you should write code.

use fm for calling search help

F4IF_FIELD_VALUE_REQUEST

Value of callcontrol-multisel is provided by the caller of the search help not by the search help. Now, go for a small report to perform a test worth a thousand words

TABLES: lfa1.
PARAMETER pa_lifnr TYPE lfa1-lifnr MATCHCODE OBJECT kredi.
SELECT-OPTIONS so_lifnr FOR lfa1-lifnr MATCHCODE OBJECT kredi.

You should be able to use KREDI, as it was delivered by SAP, for the select-options and use multiple selection, but not for the parameter. What conclusions can you draw?

...

In your case, the search help wont be able to fill other fields, so you have to explicitly handle it in the PROCESS ON VALUE REQUEST block. Use FM F4_FIELD_ON_VALUE_REQUEST to call the search-help using parameters SEARCHHELP and MULTIPLE_CHOICE, use returned records of RETURN_TAB to update dynpro fields.

NB: don't forget to handle field STEPL to fill the table-control, starting from value returned by DYNP_GET_STEPL.
