How to avoid clear data in the block in a form

Question

Hi All
I am using Oracle form 10g and db 10g.
My form i have a list item in my main canvas. It has a value of (EXPENSE,AMOUNT,SUPPLIER,ACCOUNT).
The user used to select the list item one by one and used to enter values in the each canvas assigned to the Item(expense,amount,supplier,account) and go for a save.
For instance when the user enter the value in expense ,amount and supplier and again back when the user navigate back to amount the entered value get cleared.
how to avoid the data get cleared.
Thanks & regards

Answer 1

you can use EXECUTE_QUERY built-in to populate the data when that canvas or block instance. If it need at block level write this at When New Block Instance. if it a tab page then you can write when tab page change. If need where condition, add block level where condition.
