Change log in KNA1 for custom field

Active Participant
0 Kudos

Hi All,

I have appended a custom (Z) structure in KNA1 to add 2 new fields in KNA1. Now my requirement is to activate the Change log for the two new fields. I had checked the option at data element level for 'Change Document'.

I had also tried changing/adding some configurations in BD50, BD61, etc randomly for achieving the same, but without success.

Can anyone tell the complete process for the same?
Is there any document/ white paper available for the same? please share.

Check the following thread: Change Document Object via SCDO | SCN

There is all information you need.

But which is the problem?

If you've checked "Change document" option, it should be all: your custom fields will be automatically managed

and you should see the old/new values in the change documents: of course if they're updated by standard transactions (like XD02 etc.)

I meant, in XD02, did you use some BAdI like CUSTOMER_ADD_DATA, CUSTOMER_ADD_DATA_BI and CUSTOMER_ADD_DATA_CS,

if yes did you pass values back to S_KNA1. Also to display change at field level from XD0n, did you save the cursor field in your PAI (GET CURSOR FIELD fieldname, to send it back in method GET_FIELDNAME_FOR_CHANGEDOC.)
