3154328 - Change PO Header Text will always Trigger a New Output Generation

In SSCUI 102270 - Define Texts for Purchase Order, in standard only the PO header text type F01 is delivered. In case the value in this field is changed, a new output will be generated. But in some cases, it is necessary to disable the changed output generation. 

SAP S/4HANA Cloud Public Edition 

The header text type F01 has an entry for create and change (field druvo) in SSCUI 102270. So in all cases if using this text type it will trigger a change message. 

You can add text type header note F02 via SSCUI 102270 as per KBA 2741056.
This text will then appear on the PO output in the same way as the header text.
But if changing the header note there will be no change message generated.

* Note: If there is plan to output more than one Header Text type, make sure each type used has a separate descending Print Sequence Number.
