Enable or Disable LOV based on the organization_id

Question

Hi,
I am working on apps forms, in this i have requiremnet - i need to add an Lov to a field.
Suppose we are having 3 organizations like 'org1', 'org2' and 'org3'.
When 'org1' users open the form, i need to enable the LOV for the feild.
When 'org2' users open this form, i need to disable the LOV for the feild(means, the field needs to display without LOV).
I written LOV query as
SELECT description
FROM mtl_txn_request_headers
WHERE organization_id=:parameter.org_id
GROUP BY description.
Please help me on this requirement and also let me know where i need to write the code.

Answer 1

Show_lov is a function which returns true or false, depending on how the user finished the lov. So it would be:
IF :parameter.ORG_ID IN (265,266) THEN
  IF SHOW_LOV('DESCRIPTION') THEN
    NULL;
  END IF;
ELSE
  NULL;
END IF;Anothe solution for your problem would be to disable the Lov at the item using:
SET_ITEM_PROPERTY('BLOCK.TEXTITEM', LOV_NAME, '');
