the validation check is built-in, if u declare the input field as numeric.

Reward if useful.

[Former Member]

try this code..

PARAMETERS : num TYPE char20.

IF num CA sy-abcde.

MESSAGE 'ERROR IN INPUT' TYPE 'S'.

ELSE.

MESSAGE 'INPUT OK' TYPE 'S'.

ENDIF

Hi,

You can declare a parameter of type i, p, or n.

System automatically check for the validation.

Thanks,

acctually i need to chk for quantity field

type packed with 3 decimal places

is there a FM for that

[Former Member]

Ok..then

If your field is type P with 3 decimals you need not do any checks...

[sachin_mathapati]

Hi Karan,

You can check weather a field is numeric or not by using function contains any(CA).

Eg.

if test CA '0123456789'.

*raise error

endif.

Reward points if Helpful.

i need to chk 4 general value not a single value

how can i chk for a type in dat field

the assignment is

ls_plantdata-reorder_pt = int_table-nvalue.

the thing is int_table-nvalue is char type from table control

and ls_plantdata-reorder_pt is quan i cant change int_table-nvalue to quan bt need to chk it b4 assinment only as it gives dump after assignment

[Former Member]

Right...do like this..

IF int_table-nvalue CA sy-abcde.

"Do not assign.

ELSE.

"assign value.

ls_plantdata-reorder_pt = int_table-nvalue.

ENDIF.

[Karan_Chopra_]

this only checks 4 alphanumeric values

i need to chk 4 other characters also

i mean only num value till 3 decimals needs to be added

[Former Member]

If you want check for other characters as well along with Alphabets, use the below (Slight modfication to Pervez)

IF int_table-nvalue CN '0123456789'.

"Do not assign.

ELSE.

"assign value.

ls_plantdata-reorder_pt = int_table-nvalue.

ENDIF.

I think u got my point, reward if useful

Hi Karan,

I did not get ur requirement but if the question deals with selection screens, I have an answer for it.

before u do all these things, first you need to trigger an event called AT SELECTION-SCREEN.

example code is :

AT SELECTION-SCREEN.

IF (fld name) > (value) -

---

> any logic which u need

message

endif.

[Karan_Chopra_]

its wont wrk bcoz i need to enter packed value

like 1.229 so single decimal needs to be included also

bt again problem comes if we enter 12..3 ie two decimals
