Doubt in restricting table field value

Hi,
I Want to restrict one field in my table to have only predefined values. ie, I have a field named Status which can have only 2 values either 'Present' or 'Absent'. How to make this constraint enforced in the table ?
Suggestions & ideas are very much appreciated,
Thanks & regards,
Ram

Hi ,,
Using Check Constraint it can be done.
Else
Write a trigger : before insert

How to Track the changes made to the custom table field value

I want to track the changes made to the custom table field value in table maintenance generator.please help me it is very urgent
Thanks & Regards,
Kranti

Hi Satya,
These are the steps you've to do.
1. Enable the change document flag in the data element level for the fields of the tables you want to monitor.
2. Go to transaction SCDO. Create a new change object, and add your table to this object. After generation, you'll get a function module.
3. Call this function module in the table maintainence generator screen, after the data is saved to the database table. This function module automaticallly writes the changes, with the old and new values, and the fields that were changed to the tables CDHDR and CDPOS.
4. You can keep track of the changes made to the table by monitoring these tables.

Tracking the changes made to the custom table field value

Hi all,
can we track the changes made to the custom table field values. if yes..plz specify how it can be done.
Example: if i changed the value of field 'NAME' of table 'YYHCUSTOMER'. i would like to know the old value and the new value of the field. For this, I set the flag 'LOG DATA CHANGES' in the technical settings of the table 'YYHCUSTOMER'.

-> try TA: SCU3

Passing a table-field value in Crystal to a Store Procedure in SQL Server

I have been checking all over the interenet via searches and although some seem to come close to this, its still not what I want.
Essentially I need to pass value from Table-Field record (for each record read/selected) via a paramete to a Stored Procedure(SP) in SQL Server 2205/2008. I do NOT want to be prompted for a value for this parameter each time the report is run, simple pass the value in which will be used along with other select criteria to bring back one value for the report to use in a calcuation per record.
The value of the parameter is a date, but I understand it would be better to pass it in as a varchar(8) - 'YYYYMMDD' - and then reconvert it inside the SP, as follows:
In Crystal Reports 2008 SP3, I have a formula defined as,
trans_date = ToText ({F1ARS_STMT_WS_TRAN.TRANS_DATEI}, 'YYYYMMDD')
and essential just want to pass this to the SP below ... i.e. trans_date ---> @strTransDate
I then link the key fields [EXCH_RATE_TABLE_NAME] and [TRANS_CCY_CODE] to other tables in the Database Expert, and put [EXCH_RATE_AMT] on the report and use it to calculate what I want.
This works fine when the prompt comes up and I put in a proper date, but I don't what it to prompt, but simple pass the F1ARS_STMT_WS_TRAN.TRANS_DATEI in via the fornula/parameter and let teh SQL do the rest for each record selected..
CREATE PROCEDURE [dbo].sp_GET_EXCH_RATE_AMT (@strTransDate varchar(8))     --use format 'YYYYMMDD' to represent the date as a string.
     -- Add the parameters for the stored procedure here
     -- @TransDate datetime = now
AS
     declare @TransDate datetime
     set @TransDate = CONVERT(DATETIME, @strTransDate, 112)
BEGIN
     -- SET NOCOUNT ON added to prevent extra result sets from
     -- interfering with SELECT statements.
     SET NOCOUNT ON;
    -- Insert statements for procedure here
SELECT [EXCH_RATE_TABLE_NAME], [TRANS_CCY_CODE], [EXCH_RATE_AMT]
FROM [F1CCY_EXCH_RATE]
WHERE [MAJOR_CCY_CODE] = 'BBD'
AND   [START_DATEI] =
     SELECT MAX([START_DATEI])
     FROM [F1CCY_EXCH_RATE]
     WHERE [MAJOR_CCY_CODE] = 'BBD'
     AND   [START_DATEI] <= @TransDate
END
GO
GRANT EXECUTE ON sp_GET_EXCH_RATE_AMT TO PUBLIC
GO
Thanks for any help. Can't tell the headache this has caused my both literally and figuratively.

Hello,
I moved your post to the Report Design forum. Lots of SQL help in here...
I believe the problem is due to you using a Parameterized Stored Procedure. The first thing CR has to do is connect to your DB source which requires the date parameter before it can run the query to add the date filter, it's the SP that is prompting for the parameter. Therefore the report has not run so it can't get the field value from the report until you fill in the info for the SP. Catch 22 problem.... Which came first, the Chicken or the Parameter....
The report will work as you have noted but I don't know of anyway to refresh unless parameter is filled in again....
Jason has a lot of great solutions when it comes to these dilemmas, Possibly using a Command Object may help but I believe you will still run into the same issue....
Only way I can think of is to not use a parameter in the SP and let CR do the filtering client side. Of course this means all data is coming back to the client PC as you are likely trying to find a work around for.
Thank you

Need Help in Field Symbol for Dynamically passing table field value

Hi All,
In my internal table I am having data.
I am dynamically forming table field name and substitute for the another table field name to pass DATA.
but I am getting the Variable name insted of Value ie Data.
I am using Field Symbol for this.
data:
Field-symbols <TS> type any.
field1 type string.
LOOP AT TABLEFIELDS INTO WA_TABLEFIELDS.
            READ TABLE TEST WITH KEY NAME = WA_TABLEFIELDS-FIELDNAME.
            IF SY-SUBRC = 0.
              CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
              Assign Field1 to <TS>.
                ALL_VAL-VALUE = <TS>
"After substituting the <TS> into ALL_VAL-VALUE field I need a DATA to be passed but the variable name is appending"*
         APPEND ALL_VAL.
            ENDIF.
          ENDLOOP.
kindly how to pass the value into the table.
Thanks in advance.
San

Hi,
pls assign a break point in
CONCATENATE 'WA_' WA_TABLEFIELDS-TABNAME '-' WA_TABLEFIELDS-FIELDNAME INTO Field1.
Assign Field1 to <TS>.
ALL_VAL-VALUE = <TS>
   " Put a break point here and check for the value in <TS>.
if <TS> contains value then create a work area for ALL_VAL AND PASS the Field-Symbol to that and then append thw wa into the table...
Hope this works out!!
thanks

How to get Table Field values during sync from Events like DbSyncProgressEventArgs.

Hi,
I am facing an issue related to Sync. During Sync as some Tables fails to sync, entire Session gets rollback.
Through DbSyncProgressEventArgs or DbApplyingChangesEventArgs, DbChangesSelectedEventArgs or DbChangesAppliedEventArgs, events, i want to find the Field values from that table so that i can identify which raw failed.
For example, for DbSyncProgressEventArgs, we can fetch table using e.TableProgress.TableName. But how can i get fields or Primary key value of that table row which is inserted or updated or deleted.
Please give suggestions on this.
Thanks,
Sangeetha

DbApplyingChangesEventArgs, DbChangesSelectedEventArgs has Context property that has in turn
has a Dataset property containing the change dataset being synched.

How to pass custom z table field values to smartform

hi i need to pass fields values from the table i created to already developed smartform..can anyone give me an example for this scenario

Hi,
You need to create an internal table in print program. Then fill the internal table using select statement. Now you need to declare One internal table in 'TABLES' tab of Form Interface in smartfrom.
e.g.:
IT_BKPF LIKE ZBKPF
Now call the smartform in print program & pass the internal table(declared & filled in print prog) to the smartform.

Joining tables with "similar" field values

I have run into a situation where I want to join two tables on a field called U_LotusBox.    In my main table the the feild can contain values like 1 or 2 or 3 or 1,2,3,4. That's 1 comma 2 comma 3 comma 4. My field in the second tables contains only single digit values, like 1 ,2, 3 up to 5.
When the two fields are identical I am able to retrieve data. But if my field in the main contains a value of 1,2,3 and my secondary table field value is 2 I get no data returned because the two fields are not identical.
Is it possible to have a join that is "fuzzy" meaning that if the main table field values contains the value of the secondary field value, 2 in my example would it be possible to return data?
Any thoughts would be appreciated.

Ralph,
Here in high-level details is an SQL example of creating two tables (test1 and test2) with one column in each table (col_a and col_b, respectively) to show how a join on a substring of one column can be tied to a column of another table:
create table test1 (col_a char(5))
create table test2 (col_b char(1))
insert into test1 values ('1')
insert into test1 values ('1,2,3')
insert into test2 values ('1')
insert into test2 values ('2')
select col_a,test2_tbl1.col_b
from test1 inner join test2 as test2_tbl1 on col_a=test2_tbl1.col_b or
substring(col_a,1,1)=test2_tbl1.col_b or
substring(col_a,3,1)=test2_tbl1.col_b or
substring(col_a,5,1)=test2_tbl1.col_b
col_a     col_b
~~~~~~~|~~~~~
1         1
1,2,3     1
1,2,3     2
thanks,

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

To find a field value from a table

i want to get some field value from a data dictionary table.
for eg Tragr from Mara. in Fields list it shows the field is in Mara table. but in content screen it does not showing the field at all. Actually of 220 fields of mara table only 99 fields are shown. how to view all the fields of a particular field. is there any setting is there.

Hi Deva,
When we execute any table by default SAP will display only few columns.(90 i guess) If we want to view all the columns of the table then do like this after executing the table i.e in ur table output.
Menupath->Settings->User parameters->choose radiobotton
Grid display Here u can see all the fields.
If u don't want to see all the fields then do like this.
Settings->listformat->Choosefields->Deselectall->Select what
ever fields u want using the search button in bottom and press enter. It will display only selected fields.
Some times we will come up with strange situations.
EG: In the field list some field will be there. But if u select that field from that table in select query it will give u syntax error saying field xxx does't exist in table yyy. This field is nothing but text table field. If u want to select this field then u have to select it from the text table. U can find the text table exist for some table or not in
Menupath->goto->text table. (In this case makt is text table for mara)
Just check below code for ur reference.
DATA: wa_mara TYPE mara.
SELECT SINGLE * INTO wa_mara FROM MARA .
Here if u go to mara table u have field MAKTX But above select will not return the field maktx even we are refering wa_mara to data base table mara. We have to explicitly select it from MAKT.
Hope this clarified all ur doubts.
Thanks,
Vinod.

               e.printStackTrace();
Kindly let me know where i am going wrong. MaterialNumber field is a TEXT not a lookup table field. Above fields are from the main table.
Thanks,

Hi Friends,
I got the solution. It was the error because of not having a the below statement.
limitingCommand.setPageSize(1);
As i havent used that statement, it was trying to get 1000 records, and i dont know exactly what makes this to get that error. Anyhow., As i want to use for updation, i cn live with one record.
Thanks,

Retrieving lookup field values from a main table using MDM JAVA APIs

Hi all,
am trying to retrieve the main table data...., i could able to retrieve all the data except lookup field values..., iam facing some runtime exceptions and i dont know why exactly it is throwing this exception..., i pasted piece of code where exactly the error is and the exception also.
in the below sode i set some result set definitions and passing them to retrieveLimitedRecordsCommand. it is showing some exception at retrieveLimitedRecordsCommand.execute(); command.
//*** Code ***//
supportingMainResultDefinitions = new ResultDefinition[] { rdQual ,rdFlat, rdqFlat };
                                        retrieveLimitedRecordsCommand.setResultDefinition(rd);
                                        retrieveLimitedRecordsCommand.setSearch(new Search(tableId));
                                        retrieveLimitedRecordsCommand.setSession(sessionId);
                                        retrieveLimitedRecordsCommand.setSupportingResultDefinitions(supportingMainResultDefinitions);
                                        try {
                                        retrieveLimitedRecordsCommand.execute();
                                                PrintRecords.toConsole(retrieveLimitedRecordsCommand.getRecords());
                                                } catch (CommandException e) {
                                                e.printStackTrace();

Which version are you using? Can you please try and narrow down to the offending field? You can do this by limiting the fields you provide to ResultDefinition.
