Hi,
It's very simple to make marketing transactions upload in desired Numbering Series.
All you have to do is to mention the Numbering Series code in Series cell of DTW template.
If you want to see how to enter these required data for an example in Purchase Order,
Go to SAP and open Query Generator and extract data for OPOR and POR1 with inner join which will give you all necessary info.
For Numbering series please refer NNM1 table for Purchase Order object type.
You can also refer sample template given by SAP.
Regards,
Rahul
