ADF AM datasource identifier

Question

Dear all,
We are now migrating old days Oracle Forms applications to ADF and we faced a problem that many db tables are using trigger to record audit trials log during insert/update/delete of the master table.
The problem is: the legacy system is using db level user to make connection and so in the trigger, the create_user field can directly use the global 'USER' variable to get the userid and store it.
In ADF (like other modern framework application), rather than every user create his own connection, we are using the data source pool and so all 'USER' become the same.
We are now updating the 'create_user' field by another update SQL statement to update the log table. Is there a better way of specifying the 'userid' like information/parameter when using the datasource? Thanks a lot.

Answer 1

in the transfer rule start routine you can use structure G_S_MINFO. within this structure you'll find info like datasource, infosource, datatarget, source system and so on...for datasource you need to use the fies G_S_MINFO-OLTPSOURCE.
FORM STARTROUTINE
  USING    G_S_MINFO TYPE RSSM_S_MINFO
  CHANGING DATAPAK type TAB_TRANSTRU
           G_T_ERRORLOG TYPE rssm_t_errorlog_int
