entering zero in database table

[Former Member]

Hello Everyone,

i have one field in my database table , of type NUMC length 1.

It can have value either 0 or 1.

while creating entries, i enter 0 or 1.

when i see all table entries, it show blank instead of 0.

why is this happening.

is there any solution for this.

thanks

please help

Hi,

when printing numc on screen the system trim the leading '0'. (there is a '0' but you can't see it)

If you want to see the '0' with se16 you can use CHAR instead (define a domain with '1' and '0' as valid values)

Regards, Manuel

please reward some points if this answer helps you.

Don't worry, it is 0 in the database. External formatting is presenting it as " ", in the db it is "0".

Hi

depend on how you move the field to internal table for downloading.

If you use MOVE, the system don't use any input/output conversion routines, but if you use WRITE the system use it.

So if you have ZMY_TABLE-FIELD = 0.

If you do:

MOVE ZMY_TABLE-FIELD TO ITAB-FIELD => ITAB-FIELD = 0.

OR

ITAB-FIELD = ZMY_TABLE-FIELD => ITAB-FIELD = 0.

but

WRITE ZMY_TABLE-FIELD TO ITAB-FIELD => ITAB-FIELD = SPACE

you could define a domain in SE11 (domains specify the valid values of your field).

1. Define a new domain (type CHAR) with only '0' and '1' as valid values

2. define your field with reference to the domain you have created.

Now you have a CHAR value (instead of NUMC) that accepts only '0' and '1'. And will never be converted to space.

Hi

=> is only mathematic symbol and it means THEN, I usually use it, excuse me.

Anyway you do only:

WRITE ZMY_TABLE-FIELD TO ITAB-FIELD.

Now the value of ITAB-FIELD is space.

Hi

The type N has a convertion routine that replace the zero (at the left of last number) with space.

So if you have a field type N long 5 chars and its value is 00010, you show 10, and if it's 00000 you show space.

So you should use a field type C and not type N, if you want to see the 0 when value is 0.

hi,

show your table with se16 :

1) with alv-grid

2) with abap-list

differences ?

i think , it's only the diff. formatting and representation
