SAP Netweaver Enterprise Controlling

Symptom
As of Release 4.5A, the document type for price changes and debit/credit material is always ‘PR’. The system no longer takes the corresponding Customizing setting into account (refer to Note 149139).
You have implemented Note 149139 to enable you to use other document types
After you have implemented Notes 354641 and 365466, problems reoccur with the document type, such as error message M8 164.
Other terms
Debit/credit material, price change, document type, MR21, MR22, OMW9, error M8 164
Reason and Prerequisites
You have already implemented Notes 149139, 354641, and 365466.
Solution
Customers who still require a special document type for price changes can achieve this by implementing Note 149139 and this note. This is not a correction but a modification and, as such, must be applied by the customer.
