SMP
What does SMP lookup fail mean?
Short answer
SMP popup failure means that the recipient's service metadata could not be found or loaded. Check Peppol ID, SML/DNS search, availability of SMP and supported document skills.
ID
First address
Bad Peppol ID or the scheme causes the look to search for the wrong record.
SML/DNS
Locator Layer
SML helps to find which SMP publis a metadata for a given participant.
SMP
Service metadata
MP record tells what documents the recipient supports and where his delivery service is.
Provider
Escalate Technically
If the ID is sitting, the problem belongs to the provider or record manager, not to the accountant.
