How To Fix IW901 - Deletion indicator for trans. purch. req. was not deleted (see long text)

IW901 - Overview

• Message type: E = Error

• Message class: IW - Order Processing

• Message number: 901

• Message text: Deletion indicator for trans. purch. req. was not deleted (see long text)

What causes this issue?

The technical completion of the order/network plan was reset. Purchase
requitions exist for one or more than one transaction. For at least one
of these transactions the deletion indicator for the purchase
requisition item could not be reset because an error occurred.
In most cases the cause of this is that after the completion of the
order/network plan in Customizing (transaction OMF2) a required field
was defined for the purchase requisition, which had no entry. The
system cannot process such a situation in the background.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you want to make changes to the order/network plan, which also
affect the purchase requisition, save the order/network plan and run
the report RLORD035 for the order/network. Otherwise, make your changes
and then close the order/network plan again.
