How to stream one table twice (with different names) in another schema ?

Question

hello guys,
i have to replicate one table (TAB_1) from one schema (SCH_1) on source database (DB_1) twice to schema (SCH_2) on target database (DB_2) with two different names (TAB_1 and TAB_1_SHORT). TAB_1_SHORT on target db should be a subset (eg. WHERE STATUS = 1) of TAB_1 !
how to do ? can anyone help me ?
i tried to realize that this way:
1) creating 1 capture process with 1 table rule on source db (without any subset rules to capture all changes) for table TAB_1
2) creating a propagation process without any rules
3) creating 1 apply process with a table rule for table TAB_1 without any subset_rule but with schema transformation from SCH_1 to SCH_2 (DBMS_STREAMS_ADM.RENAME_SCHEMA) => this works correct !
4) creating a subset_rule (WHERE STATUS = 1), a schema transformation from SCH_1 to SCH_2 (DBMS_STREAMS_ADM.RENAME_SCHEMA) and a tablename transformation from TAB_1 to TAB_1_SHORT (DBMS_STREAMS_ADM.RENAME_SCHEMA) for table TAB_1_SHORT => doesn`t work, no errors posted in dba_apply_error !
in another try, i tried to transform the table- and the schemaname in the capture process, with the effect, that my first table TAB_1 wouldn`t be streamed again.
i`m not sure, what is wrong. i think it must be possible to stream a table to two different targettables in the same schema on another db, isn`t it ?
hopefully greetings

Hello
Adding a normal table rule and also a subset rule would not work since the rule would be evaluated only once in the positive rule set. If the normal rule is evaluated first then the subset rule and rest of the rules would not be evaluated at all hence this would not work.
This can be done using either of the following methods:
Method 1:
     1. Use the declarative transformation on the capture/apply and rename the schema from SCH_1 to SCH_2.
     2. Now, on the apply site, set a DML Handler for SCH_2.TAB_1
     3. In DML Handler perform the following:
          a. get the column value for STATUS
          b. check if the value for STATUS=1, if yes then modify the object name to TAB_1_SHORT and execute the LCR.
          c. else do not modify the object name (leave it as it is, TAB_1) and execute the LCR.
Method 2:
     1. Add a DML Handler for SCH_1.TAB_1
     2. In the DML Handler perform:
          a. use set_object_owner method of LCR$_ROW_RECORD to rename the owner to SCH_2
          b. get the column value for STATUS
          c. check if the value for STATUS=1, if yes then modify the object name to TAB_1_SHORT and execute the LCR.
          d. else do not modify the object name (leave it as it is, TAB_1) and execute the LCR.
Please let me know if you need sample code.
