Hi,

You should use enumeration to loop through the fields of a structure.

JCO.Structure myStruct = function.getExportParameterList().getStructure("name");
for (JCO.FieldIterator e = myStruct.fields(); e.hasMoreElements(); ) {
JCO.Field field = e.nextField();
String fieldName = field.getName();
String fieldValue = field.getString();
}

the SAP parse this as a structure....that reference to internal table...

if i get the structure...how should i loop thru the things inside....

JCO.Structure input = function.getImportParameterList().getStructure("OBIMAIL");

how am i going to loop thru the sturcture....

if i not mistaken..using your method..will only get 1 line of records right....the method is loop thru the field ?

the result will be this ??

Yzme,

Please read JCO tutorial (www.winfobase.de/lehre/lv_materialien.nsf/intern01/FB09D79A41930E34C125709F0046180C/$FILE/JCo%20Tutorial.pdf) by Thomas G. Schuessler from arasoft.de

This is the best tutorial on subject I've ever read.

Unfortunately, I see no direct link on his site any more, so try the one above. Otherwise google by keywords <b>ARASoft JCO filetype:pdf</b>

my question is simple as i have stated as above...? i have read this tutorial...

i doubt that my question is still not answer.....

can i really do that ...

loop thru a structure that reference a table ....It is in ImportParameterList eg: OBIMail (Structure) > reference type -internal table--

---

meaning i am not loop thru the field...but the records...

if the OBIMail is in TableParameterList..i am sure i can loop thru each records...

Hi,

A JCO.Structure always stores a single line. So you'll only have a single record.

Yzme,

Confirmed!

JCO.Structure is single record. JCO.Table is multiple records.

Interesting enough, both JCO.Table and JCO.Structure extends extends so JCO.Table works at same time as records container (table) and "cursor" over records.

Hi,

It indeed is interesting that inspite of inheriting from JCO.Record, JCO.Structure and JCO.Table behave differently. My guess would be that, JCO.Structure is the java equivalent of a "workarea" in ABAP which always stores a single line of record.
