Hello,
Forms does not allow user to select multiple values from a list item!
The purpose of the LIST ITEM is to provide a list of values for data entry. Since data entry is for a single row of data, the LIST ITEM allows a single value to be selected. Selecting multiple values in the LIST ITEM for a single value item on a single record is not the function of a LIST ITEM.
So, if you need to select multiple values from a field and pass them through a single parameter to report, i will present you two methods to achieve this!
First Method is the text item Method:
Stept 1:
Create the text item with the values you need to send to reports.
Step 2:
Create 2 visual attributes.One visual attribute is for selected values and the other one is for deselected values
Step 3:
Create a parameter, in forms parameter layouts which will hold the selected value.This parameter will be used to set the report query clause.
Step 4:
Create a trriger for the item which you created at step 1. An example is when-mouse-click trriger.In the body of the trriger,if the item instance is clicked you will modify its visual attribute and the parameter created at step 3 will receive the item instance value.
Step 5:
In reports create a user lexical parameter(which is a large text parameter ex 2000).Ex. P_Clause.The value of this parameter is the value recrived for the form parameter you created at step 3. You report query will be like this: select * from table where &P_Clause!
Second Method is the checkbox Method:
Stept 1:
Create a checkbox item near the text item with the values you need to send to reports.
Step 2:
Create a parameter, in forms parameter layouts which will hold the selected value.This parameter will be used to set the report query clause.
Step 3:
Before you call run_report_object proc, you will need to loop through records and build you parameter with the selected checkbox instances!
Step 4:
In reports create a user lexical parameter(which is a large text parameter ex 2000).Ex. P_Clause.The value of this parameter is the value recrived for the form parameter you created at step 3. You report query will be like this: select * from table where &P_Clause!
Hope this helps.
