Re: table change history log

Hi sandy,

Do you want to achieve the same effect like PO's change log？
(I.E. Storing header data's change log in talbe CDHDR,

       Storing items's change log in table CDPOS)

Implementing such requirement,the following two steps is necessary:
1,Data element'change log should be falged.
2,Go to tcode SCDO,Generating maintenance function module.
