Dictionary structure with reference to two transparent tables

Question

Hi
I have a question about structures defined as dictionary objects.
Is it possible to define a dictionary structure consisting of the structure types of two transparent tables, i.e. to define a dictionary type that corresponds to something like this:
TYPES:
           BEGIN OF ty_s_tablejoin,
              tab1     TYPE z_table1,
              tab2     TYPE z_table2,
           END OF ty_s_tablejoin.
where z_table1 and z_table2 are both transparent tables?
I need it as a dictionary type in order to pass the structure/table into a function module as an input parameter.
There might be other ways of doing this, but it could be interesting to know if it is possible. Please excuse me if this is a weird question, I'm rather new with SAP.
kind regards

Hi Klaus,
You can't create a structure in the data dictionary from two tables.  However, you can define tables based on structures then create a structure combining both.
For example;
Create structures ZST1 and ZST2 (containing the fields of z_table1 and z_table2 respectively)
Then create tables z_table1 and z_table2, defining them based on ZST1 and ZST2
Finally create a structure (say ZST12) combining both ZST1 and ZST2
From a practical point of view, ZST1 and ZST2 should not contain the client field as when you combine them the field will duplicate.  Add the client field to z_table1, z_table2 and ZST12 before including the structres.
Hope this helps,
Nick
