Hi Fernando,
I am having exactly the same problem as you.
I have been struggling hard for several weeks without result.
So, I would like to know if you have found a solution.
-------
I also would like to use blank parameter prompts in CR2008 (previewed in SAP B1) for the foll. reason:
- I use many subreports in my CR, and not all reports are needed for any one user.
- Hence many parameter prompts are not applicable, but SAP B1 makes them mandatory
- I got around this problem by using this trick:
- I group all optional prompts on top of my Selection Criteria Screen
- For each of these parameters, I create a default value starting with a dot.
- For ex. if the parameter is "WhichStore", the default value is.MAIN (for Main Store)
- In this way, although I cannot create blank prompts, I can make it very fast to fill these by hitting TAB, period, TAB, period etc
-------
I found that parameter prompts BECOME MANDATORY if:
- You use a Stored Procedure (with input parameters) as Datasource
- You use the COMMAND WINDOW in CR2008 and create your parameters there
-------
You can make parameter prompts OPTIONAL only if you create them in Crystal Reports
- Field Explorer -> Parameters -> New
- But then you must use SELECT EXPERT to filter your data using the newly created parameter
- You can put your datasource in the COMMAND WINDOW
- The datasource can be a VIEW or a STORED PROCEDURE (but the SP must not have parameters)
--------
So, I can create blank parameters if I want, but unfortunately I am like you. I want to use Stored procedures WITH parameters - For only one reason: They can be designed ro run extremely FAST! Much faster than using views and Select Expert!
------
So, my problem is intact!
Have you sorted yours?
If not, you are left with only one choice: TAB, period, TAB, period etc
---------
Would appreciate a reply.
Best Regards,
