When running report from forms (11g) get the error: REP-0788: Warning: The value of restricted LOV parameter is not among the selectable values

Question

The parameter p_type is the LOV based on the select:

Select p_type from parameter_types where table_name = 'X' and column_name = 'Y' UNION Select '-All-' from dual;

Also the 1)Restrict List to Predermined Values is checked and 2) Hide First Column is unchecked. 3) initial value not given I tried by setting up the into initial value to 'ALL'

Please help/suggest to debug this

Answer 1

It seems that you set parameter's initial value to something that LoV query doesn't return.

For example, suppose that you used Scott's DEPT table and set LoV to return this:

SQL> select dname from dept order by dname;

DNAME
--------------
ACCOUNTING
OPERATIONS
RESEARCH
SALES

Setting initial value to eg FINANCIALS would cause that error because FINANCIALS doesn't exist among selectable values ( ACCOUNTING , OPERATIONS , RESEARCH , SALES ).

What to do? Remove initial value, or set it to one of valid values.
