Questions to Reports gurus: placeholder column's "initial value"
Hello,
I have a report with 2 queries, the master query contains some placeholder columns, and the detail query contains a formula column that sets values for these placeholders:
- MASTERQUERY: database columns, PlaceHolder1, PlaceHolder2, PlaceHolder3
|
|
-- DETAILQUERY (linked to MASTERQUERY): database columns, CF_PlaceHolder_Changer (change values of PlaceHolderX)
The problem is: for a particular record of MASTERQUERY, if the DETAILQUERY doesn't have any row then PlaceHolders are not set.
(They will keep the values from previous MASTER record). Is there any way that I can specify "initial value" for placeholder columns?
And another question: what is the formula attached to the placeholder used for?
Please help!
