Oracle Personalization, Execute A Procedure, Return Value To Screen?

[Video]

MODULE:

Oracle Inventory Management

PROBLEM STATEMENT

How does one look up values from the database and populate fields using Personalization?

SOLUTION

This should be possible using Personalization with a function on the database that retrieves values based

on other data entered on the screen by the user. The function then returns these values to a field on the

screen. An example with a movie viewlet recording and screen shots follows.

Documentation

This is a tricky area and there is not a lot of documentation on the subject. This is one good overview

note about personalization though the note does not have details on this topic:Note 743490.1-

Customization in Oracle Applications. There are discussions about similar topics on external forums like

this one mentioned only as a reference. Note that links change and this was valid as of June 2010. Here

is the link:http://apps2fusion.com/apps/21-technical/296-stored-procedure-form-personalization.

Example

Here is a simple example using a function in the database that queries values, then a personalization thatsets the value queried from dual. In this example, the function is extremely simple but more complex

logic can be used. Here is the code entered for the personalization text entered as the value for the

account. This example is defined in the miscellaneous transactions form (INVTTMTX.fmb) and passes the

item number to the function:

=select JBP_TEST_f1(''||${item.MTL_TRX_LINE.ITEM.value}||'') from dual

Note that the variable in this case is written as "${item.MTL_TRX_LINE.ITEM.value}". The text

"MTL_TRX_LINE.ITEM." is the Block and Field where the item number is written. The syntax around the

block and field name ensures that the callout is made to replace the value of the item before passing the

text to the function. You can use similar naming for your own fields finding the name of the Block and

Field using Help > Diagnostics > Examine.

Here is the example routine used - this just does a simple select from dual but other advanced logic could

be used:

create or replace function JBP_TEST_f1 (p_value in varchar2 default 'none') return varchar2 as

l_return_variable varchar2(1000) := 'No Value';

begin

select 'x' into l_return_variable from dual;

return(p_value||'+'||l_return_variable);

end;

Setup Steps

Video -Viewlet recording of personalization (05:57)

1. In SQL, create the function:

create or replace function JBP_TEST_f1 (p_value in varchar2 default 'none') return varchar2 as

l_return_variable varchar2(1000) := 'No Value';

begin

select 'x' into l_return_variable from dual;return(p_value||'+'||l_return_variable);

end;

/

* Create the function and ensure it is valid. Here is an example SQL for checking for invalids:

select object_name, object_type, owner, status

from dba_objects

where status = 'INVALID'

order by object_name

2. Open the form that you want to personalize, then choose Help > Diagnostics > Custom Code >

Personalize. In this case, the miscellaneous transactions form is opened.

3. Enter the main information about when this personalization will be active.

4. Enter the action information detailing what the personalization will do.

=select JBP_TEST_f1(''||${item.MTL_TRX_LINE.ITEM.value}||'') from dual

5. Save the changes and test the personalization.

6. In this case, the item number is passed from the screen to the database function. The function returns

the same value plus a value retrieved from the database. The value is then replaced for the Account field

on the screen.
