OPA 10.4 - batch processor and Entity

Question

Hello all.
I have a problem with the use of Entity with batch processor.
The fact is we want to use OPA with csv input named like "TARIF_ONE.csv". One different csv for every way of tarification and each time a different project that will be call by a batch process (the client need)... without the use of a configuration file !
So, if I well understood the OPA batching process, I need, for a "TARIF_ONE" project to be feed with a "TARIF_ONE.csv" file, to have a "TARIF_ONE" entity that will get all the data from the csv input file.
I've done so.
But my problem is that when I call the OPA zip by batch, the TARIF_ONE entity are well feed by the data from the csv file... but the calculation from the excel file are not made at all... and in a exporttsc file, the Entities (TARIF_ONE) are set as "unknown" for all the cases inputed...
I've setted my project like this :
my Properties file is setted like that :
Global
- TARIF_ONE (entity)
--- INPUT_DATA_ONE (attribute) : Text = "Input data one"
--- INPUT_DATA_TWO (attribute) : Text = "Input data two"
--- OUTPUT_DATA_ONE (attribute) : Text = "Output data one"
--- OUTPUT_DATA_TWO (attribute) : Text = "Output data two"
And my excel rules file is setted like below
- Declaration Sheet
-- INPUT_DATA_ONE : Text = "Input data one from TARIF_ONE"
-- INPUT_DATA_TWO : Text = "Input data two from TARIF_ONE"
-- OUTPUT_DATA_ONE : Text = "Output data one from TARIF_ONE"
-- OUTPUT_DATA_TWO : Text = "Output data two from TARIF_ONE"
- Calculation Sheet
-- OUTPUT_DATA_ONE = INPUT_DATA_ONE * INPUT_DATA_TWO
As I said, when using the batch process, the inputs attribute for the TARIF_ONE entity are well feed, but the OUTPUT attribute are not (still unknown)... and the Entity itself is said as "Unknown"... any way of reflexion to soluce that ?
Thank-you,
Philippe,

Thank you Franck for your answer.
I would have just one more question : is it possible to use different entity in the zero configuration mode ?
I tried with one data file by entity, and the entities ares not created
I tried with all the datas for entities in the global.csv file, and the same.
It seams to me that when using differents entities in a projetc for batch, we have to use a configuration file... do you confirm my feeling ?
Philippe,
Edited by: Philippe Carpentier on 25 mai 2012 03:12You can definitely load entities other than global using zero configuratiuon. To do this create a csv file that has the same name as the public name of your entity. For example if you have an entity with the name "person" then create a person.csv file for each entity instance.
You will need to have a reference to which global instance each entity instance relates to. The way to do this is to have a column named for the containment relationship for the entity to hold the foreign key to the entity instances parent.
Example
We have a global.csv with 3 globals (3 cases)
#, (number_of_persons)
1,
2,
3,And then a person.csv with 7 people which must all be link to their owning (parent) global. This is done through the containment relationship with the public name "all_persons"
#,person_name,person_age,all_persons
1,Fred,      ,27,       ,1
2,Barney,    ,28,       ,1
3,Homer,     ,40,       ,2
4,Marge,     ,38,       ,2
5,Bart,      ,10,       ,3
6,Maggie,    ,1,        ,3
7,Lisa,      ,8,        ,3Each value in the column "all_persons" is a foreign key to the global value which contains that person
