@littleinch Thank you for your answer. It actually kinda makes sense.
The thing is this list of documents belongs to an old project which has been reactivated after 8 years. So there are lots of missing parts there.
Hi everyone,
I've recently received a list of documents that have different types of P&ID for a system:
P&ID SYSTEM TESTS EDITION
P&ID SYSTEM COLLECTION EDITION
P&ID SYSTEM ASSEMBLY EDITION
P&ID
I know about the usual P&ID but what are the Tests, Collection, and Assembly editions?
I appreciate...
