Okay, the title may be confusing. It is possible to create an XML string from (inside) a called function module.

Usually this is done to keep a log of function modules that are called through webservices (done with XML).

The assumption is then that the generated XML string is stored in a table, with the name of the function

module (and perhaps more info like a timestamp).

The transformation of the Function to an XML string can be done as follows:

Assuming the function module has two parameters PARA1 and a table PARA2_RANGE.

Within the function youll then need to create a bit of code to transform th e input parameters to XML format.

This can be done like:

It is important that the parameters are copied with exactly the same name.

If this XML string is then stored in a table (with the name of the Function), then it can be used to call the

function module again.

That way you can check if the XML was correct and the values that were passed were okay.

It is possible to do this dynamically. How this can be done can be deducted from the example code below:

Dynamically fill Function parameters froman XML document

01. call transformation id source para1 = para1

02. para2_range = para2_range

03. result xml xmlstring. XMLSTRING is of type STRING

02. * Call the function again with parameters

03. *--------------------------------------------------------------------*

04. * To call the Function module again you'll need to:

05. * 1. Get the import parameters of the function (read the interface)

06. * 2. Build the internal table for the Import parameters + Values

07. * 3. Read the XML and store the result in the internal table

08. * 4. Map the parameters from the log to the parameters of the

09. * function module that will be called again

10. * 5. Call the function module
