adding one more field in extract structure maintenance

Hi Gurus,

I have already extarcted data to BW using 2LIs_13_Vditm datasource and the deltas are also loaded.

Initially when the extract structure(in LBWE) was maintained in LBWE, the field KTGRM-Acct.Assgnmt group was not selected from the POOL.Now there is a requirement to include that in the maintenance of extract structure.

My question is, can i directly add the field to the datasource in R/3,without any coding in CMOD like in enhancements, and replicate again to BW without disturbing the existing data? OR Do I have to add the field in Trans.Stru, Update rules and cube and goahead loading data.

Thanks in advance.

Regards,

Satya

    If it is available, you shouldn't need any coding. Just move the field across.

    You will need to add the field to the transfer structure and to update rules etc.

    What you want to be careful of is moving the new structure on the R3 side. Make sure you select all your deltas from R/3 and teh LIS queue is empty to ensure you don't lose data before you move the transport to R3 Prod.

    Delta could be affected; take a look at this:

    You can add any field listed in the pool of available fields directly to your LO datasource without enhancing the extract structure and coding in CMOD. But be aware to empty the delta queue and the extraction queue before, otherwise you can't change the extract structure.

    After replicating the changed datasource you have to update the relevant infoproviders, update rules and the infosource, because the new field was not known before.

    It is also recommended to reload the data from the source system in order to populate the new field for all data.
