2277298 - Extension Field On Purchase Order Gets Blank After Creating a Purchase Order Acknowledgment With Deviation


You created an extension field on the Purchase Order and after creating a Purchase Order Acknowledgment with Deviation the extension field is blank.

Reproducing the Issue

  1. Go to the Purchase Requests and Orders work center.
  2. Go to the Common Tasks - Create New Purchase Order view.
  3. Click the View All button.
  4. Type in all the relevant data and also maintain the extension field.
  5. Click the Order button.

The Purchase Order XYZ is created.

  1. Select the newly created Purchase Order XYZ (XYZ is the identification of the purchase order).
  2. Click the New PO Acknowledgement button.
  3. Change any value, e.g. the quantity.
  4. Click the Accept Deviation button.

The Acknowledgement ABC is created.

  1. Select the Purchase Order XYZ (XYZ is the identification of the purchase order).
  2. Click the Edit button.
  3. Click the View All button.

The value is blank for the extension field.


For the extension field there is an extension scenario from Material General Information to Purchase Order and hence whenever a change is done on the Material, in this case accepting a deviation of that corresponding Material the extension field calls the Material Master Data details and the data will get overridden for that Material in the Purchase Order. If the extension field gets blank in the Purchase Order this would mean that there is no value maintained for the extension field in the Material Master Data.


There are two possibilities:

1). You can deactivate the extension scenario.
2). You can add the value of the extension field on Material Master Data level.
