Use

In the single screen transactions for creating, changing and releasing purchase orders (ME21N, ME22N, ME29N), you can block individual purchase order items and specify why you have blocked the item in the item details. You can see the blocking reason on the Purchase Order History tab page, even in display mode (ME23N).

Prerequisites

You have created the relevant blocking reasons in Customizing for Materials Management under  Purchasing Purchase Order Define Blocking Reasons , and assigned a four-character alphanumeric key for each blocking reason. You have also entered language-dependent descriptions for each blocking reason, and specified whether users can overwrite the blocking reason text in the purchase order or if they must use the text from Customizing.

Features

When you block a purchase order item, you can select a suitable blocking reason on the Purchase Order History tab page in the item details.

The various blocking reasons you created in Customizing for Materials Management are provided in a dropdown list for the Blocking Reason ID field. The system copies the relevant language-dependent description to the Blocking Reason Text field . If the Customizing settings allow you to change the text, you can enter your own description of the blocking reason in the Blocking Reason Text field. If you overwrite the text for a blocking reason ID, you lose the language dependency.
