ABB irb 1660id (programming)welddata,partdata.NEED HELP!!!!

Hello!I need help.Started working on a robot irb 1660id..When creating a new welddata (weld10 or weld 20 ) what  module should I save the new weld (weld 10)?
 Sequence:
welddata
pop-up window
create -new WELD10
what to choose?
SCOPE ??? global or??
MODULE??? proc_data or???
And the most IMPOTANT question: if I create a new module,then the program,should I create a new partdata?  or it is created automatically in on the menu  PART HANLING from Product Manager? somebody can write a sequence:  create a module-then create a program-then need to switch to automatic mode,and now what I should do ,create new partdata from programdata,or create partdata from PART HANLING??? thanks in advance for the answer.
