Requisition Tax Can Be Modified On the Additional Tax Information Page For Approved Requisitions (Doc ID 2665905.1)

Last updated on MARCH 03, 2024

Applies to:

Oracle iProcurement - Version 12.2.8 and later
Information in this document applies to any platform.


In Oracle iProcurement, Release 12.2.8 and later, users are able to update the tax field values on the Additional Tax Information page for requisitions, even when the requisition is already approved and placed on a purchase order.
When trying to personalize the page, the "Readonly" attribute is set to "true"; however, the fields are still able to be updated.

The issue is noticed to occur after upgrading from Release 12.1.3.
In the Release 12.1.3 environment, the users could not update the tax details.

Due to this issue, users cannot be prevented from updating the tax values on the requisition.

Steps To Reproduce

The issue can be reproduced at will with the following steps in a Vision Demo environment.

1. View the Tax Information on the requisition.
a. Log in to Oracle Applications.
b. Navigate to iProcurement responsibility > iProcurement Home Page.
c. Click the Requisitions tab.
d. Find/search for the requisition which has an approved PO with tax information, and click the icon in the search results to view the requisition details.
e. On the Requisition Details page, in the Item Information region, the "Tax Information" link is not shown even though there is tax on the line. A personalization is needed to show the Tax Information.
f. Click the "Personalize: Item Information" link.
g. On the "Personalize Region: Item Information" page:
h. Select "Complete View" and "Expand All"
i. Find the entry "Message Styled Text: Tax Information" and click the Pencil icon to personalize it.
j. On the "Personalize Message Styled Text : Tax Information" page, set the property Rendered = true, and click the Apply button.
k. Return to Application
l. Now back on the Requisition Details page, in the Item Information region, the "Tax Information" link is shown. Click the link.
m. On the "Tax: Requisition" page, click the Additional Tax Information button.
n. On the Additional Tax Information page, in the "Tax Determining Factors for Lines" region, the various columsn such as Transaction Business Category, Product Fiscal Classification, Assessable Value, Tax Classification, etc., can all be modified manually and/or with the provided LOVs.

2. Personalize the Additional Tax Information page so that values cannot be updated here.
a. While still on the Additional Tax Information page, click the Personalize "Tax Determining Factors" link.
b. Select "Message Lov Input : Transaction Business Category".
c. On the "Personalize Message Lov Input : Transaction Business Category" page, there is a warning message:
Setting readOnly to true may make this item read-only. A read-only item is not validated on the browser and is not included in the form submitted to the server.
d. Set property Rendered = true and click Apply.
e. Return to Application
f. Back on the Additional Tax Information page, the field Transaction Business Category can still be updated.
The same is true if performing the same steps for the other fields/columns on the page.

Possible workarounds include:

a. Set profile option "PO: Retain manually updated PR Tax on PO" to value "No"; this would prevent the requisition tax changes from taking place on the PO, although this could lead to confusion when the PO and Req have different tax information.

b. Set the Rendered property = false; however, this then prevents the tax code fields/values from displaying and this is not sufficient. The business needs to show the tax information as "read only".


Upgrade from Release 12.1.3 to Release 12.2.8 or later.
