Generic extractor based on the tables CDHDR and CDPOS

Hi all,

I need an generic extractor based on the tables CDHDR and CDPOS and I do not know how to get that.

I know that CDPOS is a Cluster-table and so I can not join the tables in a FM or create a view on the tables.

Am I right that I only can get this in a FM. I use the RSAX_BIW_GET_DATA_SIMPLE FM as template and I also know the FM CHANGEDOCUMENT_READ. Can I use this FM to get the needed information.

I need the information for,

- change date

- change time

- changed by

- transaction

- fielddescription

- old value

- new value

My ABAP knowledge is not so good.....

Please can anyone give me some help.

Kind regards

Peter
