Query only specific fields of a table


I use "RFC_READ_TABLE" to query SAP tables (via JCO). Now I have to get only 2 fields of a table. Therefor I use the following code:

JCO.Table jcoTab = jcoParamTab.getTable("FIELDS");


jcoTab.setValue("ARC_DOC_ID", "FIELDNAME");


jcoTab.setValue("OBJECT_ID", "FIELDNAME");

If I execute a function with this parameters I get a table (#0) with only 1 field! I find it circuitous to parse through the String, using the table #1.

Is there a better / more elegant way?

I would be very grateful if anybody can help me.

    OK, I tried the "non-elegant" way. But the next funny thing is:

    I get a table with the design of my result table. Within this design table, there are information about the fields (name, offset, length, type). So I used this information to parse through my result. But what if e.g. field nr. 1 doesn't fill the defined length? SAP cuts the String off!

    Nothing is documented!

    This function is bulls***.
