Append datasource seen in bw, not visible in rsa3

Question

Hi experts,
This is very weird. I appended a datasource based on view from table KNBK (Customer Master Data - Bank details). I had to append a field as per the new requirements, knbk- xezer (indicator). I wrote the code in user exit to do so, replicated datasource, saw the new field in infosource as well, uploaded data to master data. The new field was empty.
When I check the datasource in R/3 side with rsa3, the appended field is not getting displayed. I wonder why.
This is the code I used:
tables: knbk.
data: wa_customer_bank type ZOXID30143.
case i_datasource.
when 'zz_ds_customerbank'.
select single xezer
              into wa_customer_bank-zzxezer
              from knbk
              where kunnr = wa_customer_bank-kunnr
              and banks = wa_customer_bank-banks
              and bankl = wa_customer_bank-bankk
              and bankn = wa_customer_bank-bankn.
endcase.

Answer 1

Whenever you append a datasource, those fields will  not be shown in RSA3 by default. You have to add those fields to the display options by going to SYSTEM -> LAYOUT -> CURRENT.
As for the new field not being displayed in the master data table, try activating the master data.
Hope this helps.
