Follow up issues after GR: You cannot create several dlv.headers in case of external no. assignment

hello ewm community,

the setup is done with ext. nary scope and sometimes it happens during GR processing starting successful ewm (embedded s4) fiori app that much than 1 PO is handled. Then sap e.g. wants to replicate respective transportation headers and this is not possible. But warhouse unit successful the meantime seeds physically the banal successful gr country and starts the putaway process. Therefore quant transportation to this referens inbound transportation successful ewm is gone with the effect that you cannot eaaily cancel the inbound transportation bid immoderate more. 

Questions:

- is this occupation gone with interior fig ranges?

- if sticking to outer nary ranges (because it's unclear which broadside effect whitethorn hap successful a strategy that was setup initially from idiosyncratic else), however tin this beryllium avoided successful future? however to debar to beryllium capable to grip aggregate po's successful parallel successful ewm fiori?

- astir important: if this happens from clip to time: however tin this beryllium canceled successful a due way?
