[Avaloq] Define task parameters to be used only in the reports

When defining a task in Avaloq, it's possible to use the pseudo keyword to mark parameters that should not be passed to the underlying task, but should still be accessible from the REP DTM sources.

This is useful if their purpose is to enhance the report functionality but they do not provide meaningful input for the task procedure itself.

They are delcared as:

i_[param_name]  pseudo  [param_type] 

eg:

i_my_param  pseudo  number

And can then be accessed in the REP DTM like any other task parameter:

task_exec.param("my_param").nr_val

[Avaloq] Get task parameter value in datamart and use it in layout

When creating a new report in Avaloq, you will typically create/edit a datamart (REP DTM source) and a layout (eg: REP SCREEN scource).

If you wish to use a task parameter to enhance the functionality offered by your report, first store the value in a variable inside the DTM (it will be at TOP level):

 [Report 2.0]  
   
 report some_task.some_dtm  
   
  datamart  
   on init  
    --get the parameter passed to the task  
    my_task_param   some_datatype   assign   [task_exec.param("my_task_param").nr_val(1)] --remember to check the DDIC for more appropriate methods other than nr_val. Also pay attention to the sequence number!  
   
   connect some_ddic as dm  
        
      ...  

then access it from your layout with:

top.my_task_param
