Hi,
    Here is the sample code to store the xml file into ABAP DB table.
First create a table called YTEST_BIN with following fileds.

Performance issue while using data type 'STRING'.

Hello All,
I have created a table for storing values of different features coming under a particular country. Since the last field 'Value field' have to hold text upto 800characters for some features, i have used the data type 'String' with character length specified as 1000. I am able to store values upto 1000characters using this. Also, the table has to hold lots and lots of value, and it will increase in future also.
Since i have mentioned the data type as 'String', I have one doubt whether this will affect the performance. Because length of most of the values in my value field is less than 75characters and in some case only it will exceed 700characters. So, my question is whether the 'String' data type will allocate the length which am specifying in the table for each entries, though the values entering is less than the specified length.
For example, if the value of my value field is 'Very High Complexity' which is of length 20characters, will the space allocation be reduced to 20 or will it be still 1000characters?
Hope someone can clarify my doubt.
Thanks In Advance,
Shino

Hi Shino,
Well it is possible to store using STRING or LCHR in the transparent tables. There are some underlyning facts here:-
1. You can only have one such field per table
2. You cannot view them in the se11 / se16 table content browser
3. You will need to maintain an additional field for storing the length of the STRING or LCHR field.
Regarding the performance:
even though ABAP allows storing STRING or LCHR type fields in the transparent tables but as soon as the lenght of the field crosses 255 chars it is not advisable to store it directly in the transperant tables.
You should store that field in the knowledge repository and only a pointer to the knowledge repository in the transperant table field.
Anyways, Since you have only one field with such a requirement then i would suggest you use STRING instead of LCHR as in LCHR you will have to mandatorily assign a length (like 1000) so even if you are storing only 20 chars or 300 chars the system will reserve a slot of 1000 chars; this is not with string as in case of string everything would be dynamic.
The result being that the reading time increases in case of LCHR.
I Hop this answered your question.

Sagar.

Create data type string

HI
There is a way to create date type string using the command
Create data type "string"...
I know that I can create data type C but string dont have any restrication so how I can hanlde it ?
Regards
Joy

Hi,
You can use the create data statement:
DATA: lo_data TYPE REF TO data.
FIELD-SYMBOLS: <str> TYPE ANY.
CREATE DATA lo_data TYPE string.
ASSIGN lo_data->* TO <str>.
Here <str> will be of type string.

Problem with data type 'STRING'

Hi All,
I have created a table named as zproject_mat and there is a field 'LONG_D' for long description and its size is not limited, so i used 'STRING' data type for this field. But the problem is: when i use this field in where condition with 'SELECT QUERY' in my abap program , it throws me an error..'The field long_d is a long string , so it cannot be used in WHERE, ON, or having conditions'.
Can anyone help me regarding this. I dont know which data type will be suitable in both conditions, LONG DESC AND SELECT QUERY.
Regards
Rahul

Hi Rahul,
As mentioned your Table name is 'zproject_mat' and there is a field 'LONG_D'.
The field 'LONG_D' will have a Data Element associated with it. Create a new input Data Element & Domain 'ZLONG' of Type CHAR with Length = 1100. This will used in the code.
For the Table 'zproject_mat', you need to need to break up your field as 'LONG_D1', 'LONG_D2', ........, 'LONG_D5' with Data Element as 'BAPI_MSG'.
To INSERT data in table:
In your code, you need to write your logic where the field 'LONG_D' is SPLIT into 5 words and saved in your table against the 5 fields.
To SELECT data from table:
In your code, again you need to write your logic where the field 'LONG_D' is SPLIT into 5 words as abaove and pass them to your SELECT query...
SELECT SINGLE *
FROM zproject_mat
INTO wa_zproject_mat
WHERE long_d1 = v_split1
AND long_d2 = v_split2........
AND long_d3 = v_split3.
The limitation of a table length is 4096 whereas of a field is 255 to make it RFC compatible. Table/Structure fields that are passed via RFC for integration have this limitation and to maintain database standards, these limitations exist.
Hope this helps.

Pranav.

Demantra - Create New Series - Mdp_matrix - Data Type String Issue

I created a new series (MDP_matrix) that has the data type as String. The display format is BLANK.
I was able to load the data into mdp_matrix table for the series i created.
However, when i look at the series in a worksheet, it does not display the string value. It display zero. for some reason, it considers the series as numeric and not string. Any idea why that would be happening?
This is on version 7.2 using SQL server/tomcat

Hi
1. Have you tried giving display format i.e ###?
2. Is your server expression something like max (mdp_matrix. column_name)?

Same Input name with different data type cause the reflection exception

I have a proxy contains couple RFCs. Two RFCs contain an argument named IN_COMPANY_CODE with data type of ZTRE_FX_BUKRSTable. Another RFC contains the same argument name of IN_COMPANY_CODE but hold different data type (String). All RFCs are in the same proxy. Complie and build the application with no issue.
But when I ran the RFC, it generates the reflection exception below:
Method SAPProxy1.Z_F_Tre_R_Pre_Trade_Fx can not be reflected. --> There was an error reflecting 'In_Company_Code'. > The XML element named 'IN_5fCOMPANY_--5fCODE' from namespace '' references distinct types System.String and MSTRFOREX.ZTRE_FX_BUKRSTable. Use XML attributes to specify another XML name or namespace for the element or types.
I realize the conflict introduced by the same name with difference data type. But I would like to know if this is fixable as a bug or if there is any best practice and/or some manual intervention to make it work.

Please install fix from OSS note 506603. After this, right-click .sapwsdl file and select "Run custom tool".

Problem with datetime data type in Web Service

Hi,
I created local ABAP proxy based on a WSDL and some of the fields for the SOAP methods has data type datetime:
name="MsgEndTimeStamp" type="s:dateTime" />
name="MsgStatus" type="s:string"/>
Since ABAP stack doesnt support dataTime data type it has created the proxy method with data type STRING. Now when I call the proxy method (consuming the service) I get an error:
<CODE>SoapFaultCode:4</CODE>
<ERRORTEXT>Server was unable to read request. --> There is an error in XML document (1, 626). --> String was not recognized as a valid DateTime.</ERRORTEXT>
I am sure others have faced the same issue. Can someone help?
Thanks

Thanks but I dont think that link is much relevant to the problems I am facing, because I cannot change the web service definition as it is used by many others. Also the target application runs on oracle so thats why some of the fields are datetime and I dont want to change that, even if I could.
I am just stuck in creating the wrapper program to call the service since the SAP converts datetime data type to string and when the messages gets to the application it cannot convert string -> datetime.
thanks anyway

Report - Want to know the maximum length of a character Data Type.

Hello,
I have to print some details which is having more than 500 characters. Is it possible to create a variable or workarea with more than 256 characters? Please help me. Its very urgent.
My actual requirement is to pass this workarea to smartform and print. So the data should be in one work area.
Regards,
LIJO

Hi,
U can declare the variable of required length for eg.1000 characters like this
DATA: w_data(1000) TYPE c.
If u r not sure of how much length u will be getting then better declare the variable with data type string .
DATA: w_data TYPE string.
Hope this clarified ur doubt.
thanks,

Database adapter not importing table having data type as WF_EVENT_T

Hi All,
I have a requirement to import a table in the Database adapter. That table is having a column of data type “WF_EVENT_T”.
When I tried to import the table in database adapter I got the error as "The following tables are not supported in the Database Adapter and were not imported".
Then I modified the table by adding one more column with some other data type and tried to import that table.
It got imported successfully but I was not able to see the column with data type WF_EVENT_T in the table.
Any pointers to this would be of great help.
Thanks.

Hi Harish
Thanks for your response.
I can create the table with the data type 'String'. However, the problem is when I try to update the table from a program in SE38 or a Function Module in SE37.
When I try to activate the PROGRAM or FUCNTION, I GET A MESSAGE THAT I MENTIONED EARLIER.
Here is the simple program that I have created that I am not able to activate
==========================================
REPORT ZTEST_STRING1.
tables: ztest.
ztest-zid = 2.
ztest-zstring1 = 'ABC'.
insert ztest.
===========================================
ztest has two fields
zid which is NUMC type
and zstring1 which is STRING type.
When I try to activate I get an error message as follows:
'ztest' must be a flat structure. You cannot use internal tables,
strings, references, or structures as components.

Component-data-type

hi,
what is the difference between component-data-type,component-item-type and data-type

what is the difference between component-data-type,component-item-type and data-typeSuppose Student have property hobbies then we use component-data-type="String".
Suppose Student have property subjects of "subject" item-descriptor" type then we use component-item-type="subject".
Suppose Student have property *firstName* of type string then we use data-type="String".
data-type
{code}
Example:
<gsa-template>
     <item-descriptor name="Student">
     ...........some properties......
     
     <table name="user_hobbies" type="multi" id-column-names="id">
<property name="hobbies" column-name="hobbies" data-type="set" component-data-type="string"/>
</table>

<table name="user_hobbies" type="multi" id-column-names="id">
<property name="hobbies" column-name="hobbies" data-type="set" component-item-type="subject"/>
</table>

<property name="firstName" column-name="firstName" data-type="String"/>
     </item-descriptor>
     <item-descriptor name="subject".......>
     ...........you may have property like subjectname, subjectcode etc
     </item-descriptor>
</gsa-template>
{code}
For deep study you can follow doc:

Runtime conversion of a string value to a primitive data type in java

can anyone of you give me an idea to convert a string value to a primitive data type during run time...i have the value and the type to which it has to be converted as String values...do you have any idea ,...pls share

String recvalvalue = inputval;
                String recvartype = inputtype;
               if (recvartype.equals("int")){
               value0 = Integer.parseInt(recvalvalue);
         else
         if (recvartype.equals("double")){
                value1 = Double.parseDouble(recvalvalue);
         else
         if(recvartype.equals("float")){
          value2 = Float.parseFloat(recvalvalue);
         else
         if(recvartype.equals("Boolean")){
          value3 = Boolean.parseBoolean(recvalvalue);
         else
         if(recvartype.equals("char")){
           value4 = (char)recvalvalue.charAt(0);
        else
        if(recvartype.equals("String")){
          value5 = recvalvalue;
         else
         if(recvartype.equals("byte")){
           value6 = Byte.parseByte(recvalvalue);
              //listA.add(6, value6);
              //     listA.g = value6;
         else
          if(recvartype.equals("long")){
           value7 = Long.parseLong(recvalvalue);
         else
          if(recvartype.equals("short")){
          value8 = Short.parseShort(recvalvalue);
         } yes i can do this but the resultant value has to be assigned to a variable of a specific type which is here recvartype .....it has to be done dynamically automatically..if we know what type of data is that we can convert and assign to the type but we donot know when we run the program as the program will be supllied by someone and has to be executed

"Schema validation found non-data type errors" error when passing a string value to date field in infopath

Hi,
I have an infopath web brower enabled form. In the form i have a date field.
I am passing the data from the database to that field using the C# code.
But, as the field from database is coming as string, i am getting an error, and i am not able to assign the value.
I get the date value from database as "3/25/2011 12:00:00 AM"
I used the below code:
[CODE]
if (objInfopathFormcData.myRecievedDate != null)
myRoot.SelectSingleNode("/my:myFields/my:field97", NamespaceManager).SetValue(objInfopathFormcData.myRecievedDate);
[/CODE]
I am getting the error as "Schema validation found non-data type errors".
How to set the value for a date field in Infopath.
Thank you

HI,
I fixed it:
Below code is used to fix:
[CODE]
XPathNavigator xfield = null;
DateTime dtmyRecievedDate;
dtmyRecievedDate = Convert.ToDateTime(objInfopathFormcData.myRecievedDate);
if (objFormcData.FcCompletionDate != null)
xfield = myRoot.SelectSingleNode("/my:myFields/my:field97", NamespaceManager);
DeleteNil(xfield);
xfield.SetValue(dtmyRecievedDate.GetDateTimeFormats().GetValue(5).ToString());

Issue 1:-
I am reading notepad: getting all column and values in my data table now while inserting for date and time or integer field i need to do explicit conversion how to write for specific column before bulkcopy.WriteToServer(dt);
Issue 2:- Notepad does not contains all columns nor in specific sequence in that case i can add few column ehich i am doing now but the issue is now data table will add my columns + notepad columns and while inserting how to assign in perticular colums?
sudhanshu sharma Do good and cast it into river :)

Hi,
I think you'll have to do an explicit column mapping if they are not in exact sequence in both source and destination.
Have a look at this link:

Good Luck!
Kaur.
