Extracting Values of a Field from a Database Table in SAP ECC System

Question

Hi,
I downloaded Extracting Values of a Field from a Database Table in SAP ECC System Using MII 12.0
senario from sdn. I'm trying to do that senario in MII 12.05. But I have problem with section 6 in page 7 (you can supply senario from sdn)
"6- Under the loop of Repeater, use action u2018Rowu2019 to append just the string part of the WA which will display only values for field u2018Batchu2019"
I did not find WA elemen in Output element of Repeater_0
How can I create WA element?
Thanks.

Cemil,
Set up a SAP JCo Interface action block.  Use the RFC name RFC_READ_TABLE.
In the link editor map the table to "MARA", set RowCount to something small (20 is good sample size) and create an xml transaction property named FIELDS and copy the following into it:
<?xml version="1.0" encoding="UTF-8"?><FIELDS>
      <item>
        <FIELDNAME>MATNR</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>MTART</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>BSTME</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>XCHPF</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
      <item>
        <FIELDNAME>DATAB</FIELDNAME>
        <OFFSET/>
        <LENGTH/>
        <TYPE/>
        <FIELDTEXT/>
      </item>
    </FIELDS>
Then link the Transaction.FIELDS to SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/TABLES/FIELDS}.  You may run into problems with two other fields and optionally they can be removed (set link type to remove xml).  I usually remove them initially for testing.  The two fields are:
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/NO_DATA}
SAP_JCo_Interface_0.Request{/RFC_READ_TABLE/INPUT/DELIMITER} (or you can set this to something like a semicolon,";" or tilda,"~".  I find it easier to caclulate position by length, but that is my own idiosyncrasy.)
Once you get this one working, we can explore how to do filtering on the dataset.  Your output should be something like this:
<?xml version="1.0" encoding="utf-8"?>
<RFC_READ_TABLE>
  <INPUT>
    <DELIMITER />
    <NO_DATA />
    <QUERY_TABLE>MARA</QUERY_TABLE>
    <ROWCOUNT>20</ROWCOUNT>
    <ROWSKIPS>0</ROWSKIPS>
  </INPUT>
  <TABLES>

Add a repeater sourced on:
SAP_JCo_Interface_0.Response{/RFC_READ_TABLE/TABLES/DATA/item}
Link your repeater output to a tracer with this:
Repeater_0.Output{/item/WA}
What you will see in each tracer message is a single line of data with all the fields contents concatenated together.  You can look up what each field in the string represents by the length of the field as returned in the Response segment of the RFC_READ_TABLE rfc.  Then you can parse out the data you are interested in.
Give this a try and let me know how you succeeded.
By the way, I could not find the scenario you referred to.  Can you post a link?
Regards,
Mike
