BOM issue

Hi all,

Iam creating an ABAP report program to find the Bom changes for a period of time .

The Bom changes is further subdivided into

[1]

quantity changes in the BOM.

[2]

All changes in the BOM.

I use the cdhdr and cdpos tables to find the changes.

If I look into the cdpos table the tabname field may contain stpo mostly,but sometimes the field contains stzu,stas AND MAST also.

So for my requirement,Will it be okay if I take into account only the stpo table.

What changes in the BOM result in the other tables(stzu,stas,mast) getting displayed in the stpo~tabname field.

Other than the CS02 transaction,how can one change the BOM.

Please advice how to proceed....

Thanks

Koh
