Validation check in parameters

Former Member — Tue, 02 Feb 2010 13:56:52 GMT

Hi experts,

I have a selection screen with 2 parameters p_a and p_b.

Suppose I input any value in p_a and leave p_b blank,

ideally in the output I should get all the results in which p_a

condition is satisfied.

But what is happening is that the select query searches for the

entry where p_a is equal to the value entered, and also it searches

for p_b equal to blank.

Since there is no combination of this type, sy-subrc is always 4

What should I do to rectify this issue?

The select query I am writing is:

select emaildate

emailtime

from zabc

into table it_zabc

where a = p_a

and b = p_b.

This query looks wrong to me. What can be a correct one?

Thanks,

Ajay.

Use SELECT-OPTIONS instead of PARAMETERS

Hello,

Using parameters, the select query will always look for the exact match while retreiving the records. If you want the desired output declare them as select-options instead of parameters.

If you want to manage just one selection, u need to use the select-option instead of the parameter, so u have 2 chance:

A) Define p_a and p_b as select-option but having the format of parameter:

TABLES: BKPF.

SELECT-OPTIONS: SO_BUKRS FOR BKPF-BUKRS NO-EXTENSION  NO INTERVALS,
                SO_GJAHR FOR BKPF-GJAHR NO-EXTENSION  NO INTERVALS.

SELECT * FROM BKPF WHERE BUKRS IN SO_BUKRS
                     AND GJAHR IN SO_GJAHR.
ENDSELECT.

B) Transfer the parameters to a range:

TABLES: BKPF.

PARAMETERS: P_BUKRS LIKE BKPF-BUKRS,
            P_GJAHR LIKE BKPF-GJAHR.

RANGES: R_BUKRS FOR BKPF-BUKRS,
        R_GJAHR FOR BKPF-GJAHR.

IF NOT P_BUKRS IS INITIAL.
  R_BUKRS(3) = 'IEQ'.
  R_BUKRS-LOW = P_BUKRS.
  APPEND R_BUKRS.
ENDIF.

IF NOT P_GJAHR IS INITIAL.
  R_GJAHR(3) = 'IEQ'.
  R_GJAHR-LOW = P_GJAHR.
  APPEND R_GJAHR.
ENDIF.

SELECT * FROM BKPF WHERE BUKRS IN R_BUKRS
                     AND GJAHR IN R_GJAHR.
ENDSELECT.
