This is expected.
Memberships generate a PDF in Member profile → Documents.
For services, contract creation depends on the “Contrat applicable” setting in the service configuration (exact in-product label).
Key point: if “Contrat applicable” is off, no PDF is created → nothing will appear to open on the member record.
Where to check / fix (generic)
Open the service settings.
Enable “Contrat applicable.”
Save.
For existing items without a PDF:
Generate the contract manually (if available), or
Update / recreate the item to produce the PDF, or
Ask support to generate the contract.
Quick FAQ
