Hi Nik,

The option to turn off testing for errors is a novel idea, but can be done easily enough with the snippet from this article.

A simple query and an if statement will suffice to prevent the creation of duplicate records based on the ALTKN field in KNA1. If your source structure is called XD01S and the parameter is p_check then the code would look like this:

select single KUNNR from KNA1 into BKN00-KUNNR
 where ALTKN eq XD01S-ALTKN. 
if sy-subrc eq 0 and p_check eq 'X'. 
  write: / XD01S-ALTKN, "Customer already loaded.".
