selection screen options

select-options:sid FOR Zxxx-ID NO-EXTENSION NO INTERVALS.

with the first statement ,

if u doesnt give any input value for the select-option , it will fetch all the values when used in select query

but with the second statement , if the parameter value is empty it will not fetch any record when used in select statement

Hi Ramudu,

If you declare a Variable as a Parameter You should take care of validations

Ex: Like in where condition MATNR = P_MATNR.

Suppose if you are not given any value in the selction screen

This selection screen will not work ( i.e you won't get any material's)

If it is select Option

If you are not given any value in the selection screen, It will give you all the materials .

Thanks

Sekhar.

Hi,

select-options:sid FOR Zxxx-ID NO-EXTENSION NO INTERVALS

defines field SID aa selection range table as if defined by ABAP statement

DATA: SID type range of Zxxx-ID with header line .

NO-EXTENSION NO INTERVALS restricts the screen I/O to one field. In this field you can use wildcards defining patterns or use double-click to set compare operator >,<,<=,>=,....

The only allowed comparison operator for database retrieval or field compare is IN. The input field defined is for field SID-LOW of ABAP range SID.

parameters : sid like zxxx-id.

defines a simple input field.

All operators =,>,<,<=,>= and pattern operators CP, CA, NA but not range operator IN are allowed for database retrieval or field compare.

Note: Although the screen looks identical, the definition and use is very different.

Regards,

Clemens

Hi,

First statment and second looks to be same but works differently .

First statment will return all records from the table when queried if no value is given.

Second will return only value with SPACE which is checked against .

First statement will need "IN" option in query .

Second cannot use "IN" option.

For First statement Table type should be declared if refered to ..

Second statement tbale type declaration is not needed ..

Hope this is clear.
