Is ME28 transaction Obsolete?

[SAPSupport]

Hi,

In one of the SAP OSS Note 1803189, it is mentioned ME28 is obsolete and ME29N is new txn. ME29 is used to release PO in Mass and ME29N is used to release individual PO. I do not see ME29N has option to release multiple POs. 

Please confirm ME28 is still valid txn to use in SAP.

As referenced in Note 1803189, ME28 is indeed no longer supported -

With the introduction of the 'N' or 'Enjoy-based transactions', ME28 was not included in these updated transactions, and development of new functions (eg BADIs, BAPIs, etc) all reference 'N' based transactions, with ME28 not being included.

(from the note itself):

"ALL developments that are done for the business object Purchase Order and Purchase Requisition are based on these transactions, IDocs and BAPIs.
Future enhancements that are related to Purchase Order or Purchase Requisition will only be done for the "new" transactions, IDocs and BAPIs."

While ME28 is still present / usable in its limited form, it is possible to use it -but it is no longer supported by SAP.

You should consider looking at individual release of POs via ME29N using additional Release Strategy and Workflow.
