Hi,
Have you ever worked on "Extended Computer Aided Test Tool" ? Tcode for this is SECATT. Your requirement can be achieved through this. But technically, it requires really good effort and unfortunately I cannot guide you the steps here.
Anyways, your problem is a “known problem” with PS conversions, but a couple of options exist.
The most efficient is that the projects are created by copying from template (LSMW run 1 for CJ20), and as second step maintained for individual WBS (LSMW run 2 for CJ20), where e.g. WBS data can be maintained and underlying activities added, but even for the second one, you face a problem if the activity lists/structures vary a lot in quantity and levels.
The bottom line is that if the projects to be imported do not fit into templates, the system should have the same logic structurally. Programming the LSMW or ECATT requires so much, that it doesn’t make sense for below 1000 projects. In this specific case for 100-150 projects, if a “copy from template” approach doesn’t work, the most efficient solution by far is a column wise ‘copy-paste’, grouped in advance like it is done in Excel.
There are some other options you could take since you are confused with levels.
You can use LSMW in a different way to upload the project
1. Create project definition & Level 1 WBS & one Level 2 WBS element manually.
2. Now while carrying out recording for LSMW in cj02, use Insert Line option above Level 2.
3. In the Excel file, Keep all the down below WBS elements at level 2 only.
4. After uploading the complete file, carry out function “Derive Structure” for project.
This method is useful if you are copying the coding mask of a superior WBS into subordinate WBS elements.
ELSE, you may go with the BAPI as suggested by Saurabh
I hope this may help you.

Amit
