How to restrict io field length...?

hi,
how can we restrict the io screen field length on the screen with out changing field type....
Regards,
Anil.

Hi ,
Do you want to restrict the display or the input length.
In case you want to restrict the display with the select-options or parameters then simply use the extension
... VISIBLE LENGTH vlen
Effect
This addition allows you to shorten the visible length of the corresponding screen field on the selection screen to vlen.
and in case you want to restrict it based on the number of characters then check out the following code.
PARAMETERS p_test TYPE c LENGTH 10.
DATA test TYPE i.
AT SELECTION-SCREEN ON p_test.
test = STRLEN( p_test ).
IF test > 4 .
MESSAGE 'Length greater than 4' TYPE 'E'.
ENDIF.

How to change the field length in standard sap program.

Hi All,
How to change the field length in standard sap program.
Urgent
Example:
Text1 type c length 75,
To change :
Text1 type c length 150,
Point will be rewarded..
Thank you,
Vikram.C

If the only solution is to change the sap standard program, simply change the program, it will prompt for an access key. This key can be retrieved in the SAP support portal (service.sap.com) at keys and requests, sccr keys, register object.
Sometimes these actions are outsourced to a competence center, so maybe youre not entitled to do this, in any case ask a resident senior developer for support.

Assign Fields to Field Selection Groups
To define whether a field is hidden or displayed, or whether an entry is mandatory or optional in material master maintenance, you must assign the field to a field selection group. You may assign a field to one field selection group only.
Before including customer-defined fields in a field selection group together with standard fields, or assigning standard fields to a different field selection group, familiarize yourself with the assignment of fields to field selection groups in the standard R/3 System.
Standard settings
The values of the field selection groups have been preassigned as follows:
001-110 Material master for industry
111-120 Reserved for customers (except where the values are already in use)
121-150 Material master for industry
151-210 Material master for retail
211-240 Reserved for customers
Recommendation
If possible, use the setting in the standard R/3 System. No further action is then required. If you want to make individual fields inaccessible, the easiest way is to group them together in a single field selection group and to set it to Display or Hide.
Activities
1. Check the setting in the standard R/3 System.
For this, you need to know the data screen on which the relevant field appears in the material master, and the name of the screen field, for example, MARA-MEINS in the case of the base unit of measure.
2. If necessary, change the assignment of fields to field selection groups as required.
Further notes
In the case of long texts, you define whether the entire screen is hidden or displayed, or whether entries are mandatory or optional. For this reason, each screen has been assigned to one of the following dummy fields:
LTEXT_BEST Purchase order text
LTEXT_GRUN Basic data text
LTEXT_IVER Internal comment
LTEXT_PRUE Inspection text
LTEXT_VERT Sales text

Restrict TextEdit field length to 240 chars

Hi,
In my Web-Dynpro application, I need to restrict the TextEdit field length to 240 chars maximum size.
The users shouldn't be allowed to enter more than 240 characters!
Best Regards,
Amol

Hi,
try creating a simple type under the dictionaries->logical dictionary->data types->simple type of type String and in the Definition tab set the max length to 240. create a value attribute under the context and set the type to the simple type created and bind it to the Input field.
This will restrict the length to 240.

How to increase the Field length

Hi All ,
I have to increase the Standard Field length in a transaction.
is that possible ? if yes , how we can do that ?
thanks and regards,
Deepak Rana.

it is not advisable to change the format of standard SAP table fields. most of them are being used in many different places, you will have a hard time making sure that all functionality still works OK after such a change.
maybe you can append new fields to ADRC and work with these.
Greetings

Hi,
For MIRO, SAP doesn't provide any field selection facility, this can be done by creating screen variants for MIRO in OLMRLIST
You can also use transaction SHD0 for creation of Screen variants of MIRO.

How to restrict sensitive fields while WF in Approval process?

Hi Gurus,
we have a requirement where few fileds should be restricted while WF is in approval prcess and an error msg should display to them that Wf is in process and you cannot change the values.so please help me out on this.

Hi,
you could fiddle around with lock mechanisms.
But ottherwise you would have to do some additional programming at the transaction side.
If there is a badi, use fm SAP_WAPI_WORKITEMS_TO_OBJECT to retrieve the workitem for that workflow.
Kind regards, Rob Dielemans

How to restrict field values

Hello Experts,
I got a basic question to ask. Iu2019ve created a custom table and then attached a check table with one of its field. This field is not PK. Now through help u2018F4u2019 I can see the values coming from check table. But other then those values let say if I enter any data (any garbage) it is getting stored in the table. Can somebody tell me how to restrict this field so that user must have to select the values from the list not on his own?
Thanks

Do a validation of the input that the user gives.
Select single xxx from Ztable
where xxx ( eq selection screen parameter )
( IN select options )
If Sy-subrc eq 0.
Through an error message
Message e000 'Pls enter a correct value for the XXX '
Endif.
The whole code should be under AT selection screen event.
i guess you will agree with this solution.
Thanks,
Karthik

Leading Zero w/ variable field length...

I'm creating a form in which I need a particular field to:
- Accept/Display a leading zero (or multiple leading zeros);
- Accept numbers numbers;
- Have a maximum field length of six numerals, but with the ability to accept fewer;
- Display an error message if the above criteria are not met.
I have some code (see below), but don't know how to make the field length variable.
var fmt = /^\d\d\d\d\d\d$/;
if(event.value != "")
if(!fmt.test(event.value))
app.alert("Incorrect format, field must contain numbers only.");
event.rc = false;
Make sense...? Can anyone help...?
Thank you.

This drops the leading zero(s) and does not display the error message.
Adjustments...?
Thank you for your promp reply.
