Create Selection with ABAP

Question

I'm new in ABAP. I want my code to create a selection where I can enter a number and it shows me the list of my previously created customers.

this is the code:

REPORT ZBSP_CODING.

DATA: ls_ZBSPCUSTOMERS TYPE ZBSPCUSTOMERS,
  lt_ZBSPCUSTOMERS TYPE TABLE OF ZBSPCUSTOMERS,
  lv_KUNNR TYPE KUNNR.


SELECT-OPTIONS p_KUNNR FOR lv_KUNNR NO INTERVALS.


SELECT * FROM ZBSPCUSTOMERS INTO ls_ZBSPCUSTOMERS WHERE KUNNR IN p_KUNNR.
  WRITE: / ls_ZBSPCUSTOMERS-KUNNR,
         / ls_ZBSPCUSTOMERS-NAME_FIRST, ls_ZBSPCUSTOMERS-NAME_LAST,
         / ls_ZBSPCUSTOMERS-STREET, ls_ZBSPCUSTOMERS-HOUSE_NUM1,
         / ls_ZBSPCUSTOMERS-POST_CODE1, ls_ZBSPCUSTOMERS-CITY1.
ENDSELECT.

the problem is, it won't show me any customers. What am I doing wrong?

Answer 1

There will be two cases.-

1. Either ZBSPCUSTOMERS table doesn't contains any data.

2. or might be data mismatch for leading 0's in data value for KUNNR field. So, Add these line-

 SELECT-OPTIONS p_KUNNR FOR lv_KUNNR NO INTERVALS. "-------add below lines----- LOOP AT p_KUNNR. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING input = p_KUNNR-low IMPORTING output = p_KUNNR-low. MODIFY p_KUNNR. ENDLOOP. "-------End of addition------------- SELECT * FROM ZBSPCUSTOMERS INTO ls_ZBSPCUSTOMERS WHERE KUNNR IN p_KUNNR. WRITE: / ls_ZBSPCUSTOMERS-KUNNR, / ls_ZBSPCUSTOMERS-NAME_FIRST, ls_ZBSPCUSTOMERS-NAME_LAST, / ls_ZBSPCUSTOMERS-STREET, ls_ZBSPCUSTOMERS-HOUSE_NUM1, / ls_ZBSPCUSTOMERS-POST_CODE1, ls_ZBSPCUSTOMERS-CITY1. ENDSELECT. 

CONVERSION_EXIT_ALPHA_INPUT Function module adds leading 0's in value. for ex- if DE size is 10 digit than if you enter 102, then it'll convert fron 102 to 0000000102.

谢谢大家，就像@divScorp提到的那样，它是F8按钮而不是Enter-Key
