For project reason I need to fill some excel.
The content of each column comes from content in SE11:
In order to avoid such boring task, I write a small ABAP class to automate it.
This class will first read corresponding database table name based on CRM settype id, then call function module DDIF_NAMETAB_GET to get all metadata of each table field, and then send the data to clipboard.
Once done, put the focus on the first cell of content row, press Ctrl+V, all the data from clipboard will be copied into excel automatically.
The source code could be found below:
