In part one for this tutorial I quickly shown you how to create a chart customizing using Chart Designer, in this part I will show how I store and use such customizing. For the beginning I'll tell you that there are many ways to store the customizing, you can keep it in GOS, or in APP server or load it directly from PC, but my favorite one is to keep the customizing in standard texts (SO10) and read it from there. It's easy to do changes there and it can be restricted in authorizations who can do changes for such text.
So I'll go to SO10 and create new text for customization there:
Then I'll paste the XML content here and save:
 
After it's done I can prepare a module to read the text, replace title and subtitle and to create an xstring from it. I will use this xstring in next part of tutorial to render the chart.

Importing parameters:

I_TEXTNAME TYPE RSSCE-TDNAME  -> text name
I_TITLE TYPE CSEQUENCE -> our titile
I_SUBTITLE TYPE CSEQUENCE ->our subtitle

Returning parameters:

VALUE( C_XSTRING ) TYPE XSTRING -> I'll use that in next part

Implementation:
