How To Fix 29081 - No selected items valid on & - no allocation to operation possible

SAP Error Message - Details

• Message type: E = Error

• Message class: 29 - Bills of Material

• Message number: 081

• Message text: No selected items valid on & - no allocation to operation possible

What causes this issue?

You want to change items on the <LS>valid-from</> date.
You either entered this date directly on the initial screen in the
field <LS>Valid from</>, or the system determined the date from the
change number you entered on the initial screen.
As none of the selected items is valid on &V1&, you cannot change these
items on this date and therefore cannot allocate any of them to an
operation.
You have to change the validity period of the items, defined on the
item overview screen by the fields <LS>Valid from</> and <LS>Valid
to</> or the <LS>change number</>.

How to fix this error?

If you want to allocate these items to an operation, make the change
within the validity period of the items.
There are two ways of doing this:
If the BOM has not yet been changed with history (with reference to a
change number), choose the valid-from date of the items as the
<LS>valid-from</> date on the initial screen.
If the BOM has already been changed historically, make the change using
a change number.
Choose a change number which has a valid-from date within the validity
period of the items: the selected items may already have been entered
or changed with reference to a change number.

• What is the cause and solution for SAP error message 29081 - No selected items valid on & - no allocation to operation possible ?

  The SAP error message "29081 No selected items valid on & - no allocation to operation possible" typically occurs in the context of production planning and execution, particularly when dealing with production orders, operations, or material allocations. This error indicates that there are no valid items available for allocation to the specified operation in the production order.
  Causes:
  
  Material Availability: The materials required for the operation are not available in the required quantity or are not available at all.
  Incorrect Selection: The items selected for allocation may not be valid for the specific operation or production order.
  Status of Production Order: The production order may be in a status that does not allow for allocation (e.g., it may be closed or technically completed).
  Routing Issues: The routing for the production order may not be correctly defined, leading to no valid operations being available for allocation.
  Batch Management: If batch management is enabled, the specific batch may not be available for allocation.
  Stock Type: The stock type (e.g., blocked stock, quality inspection stock) may prevent allocation.
  
  Solutions:
  
  Check Material Availability: Ensure that the required materials are available in the correct quantities. You can check this in the Material Master or Stock Overview.
  Review Production Order Status: Verify that the production order is in a status that allows for allocation. If it is closed or technically completed, you may need to reopen it or create a new order.

  Re-select Items: If you are manually selecting items for allocation, ensure that you are selecting valid items that correspond to the operation.
  Check Batch and Stock Type: If batch management is in use, ensure that the required batch is available. Also, check the stock type to ensure it is not preventing allocation.
  Use Transaction Codes: Utilize transaction codes like CO02 (Change Production Order) or CO03 (Display Production Order) to review the details of the production order and its operations.
