Validation while create data type

[Former Member]

HI All ,

I have a pop-up in my report that user can create data type in didc,

There is a simple way to support validation for data types ,

I have pop-up where the user need to provide name of attribute

he need to create and the data type for it (char ,string ,int etc )

and he also need to provide the leng of the attribute he want to create

(e.g. char10 ) and also decimal places .

the issue here that i need to do some validation in the pop-up

for e.g. if user choose

case 1 
name     - attribute1 
datatype  - string 
leng   - in this case he dont need to provide leng (string ) 
dec - dont need to provide (string )

case 2 

name     - attribute1 
datatype  - char  
leng   - 10
dec - dont need to provide (char )

Any idea how to do this validation in a simple way (maybe to use standard functionlity)

Hi Alex,

What kind of pop-up are you using? Is it a pop-up screen or any other function for pop-up?

Hi Alex,

There are a few FMs starting with DD_DOMA and DD_DTEL. Please check if any of these can help you to validate the data elements and domain creation.

HI ,

DO you have some example how to use this FM for instance

for string or int or char ?

Hi Alex,

I do not have any example.

If you are not comfortable with using these FMs validate manually.

Set a user-command for the list box. This will trigger the PAI and the PBO when the user chooses the data type in list box. In the PBO check for the value selected in the list box and gray off the unwanted fields. Say if the value of list box is STRING then set SCREEN-INPUT = 0 for the field LENGTH and DEC.

Please check the help on screen programming for more details on how to gray off or hide fields in screens.

HI Immanuel ,

Do you mean to something like this ?

LOOP AT SCREEN.
    IF screen-name = 'S_C_STR_POPUP-BASE_TYPE' AND BASE_TYPE = 'String'.
      IF screen-name = 'GV_LENG' OR screen-name = 'GV_DEC'.
        screen-input = 0.
      ENDIF.
    ENDIF.
  ENDLOOP.

how i modify the screen since the second if will not work .

Hi Alex,

Yes. You have to have some code like that.

CASE List box content .

WHEN 'STRING'.
LOOP AT SCREEN.
   IF SCREEN-NAME = 'LENGTH' OR
      SCREEN-NAME = 'DEC'.
   SCREEN-INPUT = 0.
   MODIFY SCREEN.
   ENDIF.
ENDLOOP.

WHEN 'CHAR'.
LOOP AT SCREEN.
   IF SCREEN-NAME = 'LENGTH' OR
      SCREEN-NAME = 'DEC'.
   SCREEN-INPUT = 0.
   MODIFY SCREEN.
   ENDIF.
ENDLOOP.

WHEN 'INT'.
LOOP AT SCREEN.
   IF SCREEN-NAME = 'DEC'.
   SCREEN-INPUT = 0.
   MODIFY SCREEN.
   ENDIF.
ENDLOOP.

ENDCASE.

.

Regards,

Immanuel.

Hi Alex,

Fill the FctCode field in the field attritbute of the list box. Only after the function code is assigned to the list box the PAI and PBO will be triggered for the screen.

The attribute of the field is chang.

CHAR:screen-invisible = '0'

STRING:screen-invisible = '1'

or

CHAR:screen-invisible = '1'

STRING:screen-invisible = '0'

Hello,

Just place a debug point in routine PERFORM F4PROZ of function module DD_SHLP_CALL_FROM_DYNP. Then execute your standard f4 functionality of predefined type in SE11. It just holds few steps which can easily taken into your custom code.

You can get this same search help in your program with screen fields disabled and letting the user chose it in the force mode of F4_INIT_TABLE_VALUE_REQUEST.

Is this popup done through modal window popup or any function modules.

if its a function module i doubt whether it triggers the validation written.

[Former Member]

HI Keshav.T ,

The event that you mentioned in your previos post is trigger when the user choose the F4

but i dont understand how can i use it .

what i want to do is when the user press F4 and choose datatype to trigeer event and than

decide if to omit some field from the popup

.

I created for the popup a function module with call screen.

Thanks

Alex

The event that you mentioned in your previos post is trigger when the user choose the F4
but i dont understand how can i use it .

In Se11 when f4 is pressed for predefine data types that routine gets triggered.

I created for the popup a function module with call screen.

Then your validation for module will not trigger. It will get triggered for screen fields. Not for the input text boxes provided by fm popup.

HI Keshav.

What i did is created a popup with FM in the popup i have 4 field

the field with the data type which i want to trigger event to it is domain and not ref to FM

The ppoup have 4 field

attr name

datatype

length

decimal

so from what you are say there is not option to trigger event when the user press F4

and choose a entry from it ,

since what i want to do is that if user for instance chose string i want that the next to fields (length and dec ) will be

remove from the popup since he dont need them .

and for he choose char the the decimal field will remove from the popup

Any idea how to solve this issue ?

Regards

Alex
