how to maintain PO version in case of po amendments
In the case of procurement transactions extending over a longer period of time (for example, in the procurement of capital goods), you may need to differentiate between various versions of the purchasing document. You may also need to refer to one particular version when corresponding with the vendor.
The Version Management facility enables you to generate and manage versions of purchase requisitions and external purchasing documents such as POs. A version groups together the change documents generated in the course of subsequent processing of the relevant document. A version thus indicates the revision level of a document (version 0 = original document, versions 1 + = revisions) and provides the user with an overview of the various changes that may have been made in the course of time.
Version Management thus represents an extension to the hitherto existing change documentation functionality for internal and external purchasing documents.
Version Management can be used in connection with purchase requisitions (ME51N, ME52N and ME53N only), RFQs, purchase orders, contracts, and scheduling agreements.
The following prerequisites must be satisfied before a version of a purchasing document can be deleted:
The changes made in the version must have been reversed (cancelled, revoked)
All open messages must have been deleted
1) Go to SPRO-MM-Purchasing-Version Mgmt-Setup Version Mgmt for External Documents
Activate Version Mgmt against your Doc type and Double click on that Doc type NB then in next screen in Control data tab mark all the fields and in Field Selection set all the Fields as Required entry Except Posting Date and save.
2) go to SPRO-MM-Purchasing-Version Mgmt-Define Reasons for change
Create one New Reason Called Xyz something and give text and save.
3) Go to SPRO-MM-Purchasing-Version Mgmt-Set up change Displays
Here Select Doc type say NB and Give Table name say EKPO for PO and EBAN for PR, Give Field name say MENGE for qty and save.
Hope it helps...
Thanks & Regards,
