One certificate, six heats: matching MTRs on real material data
Every material traceability scheme works beautifully in the clean case: one certificate, one unique heat number, look it up, done.…
Read NowAssembly and multi-tag documents are where cover pages get painful. The general arrangement drawing covers one model, and that model ships against forty tag numbers. The customer’s cover sheet wants all forty listed, correctly, at every issue. Same for the instruction manual that covers a whole product family.
Typing them is how it usually gets done, and typing them is how a transposed tag number ends up on a submitted document. A tag error on a cover page is exactly the kind of thing an EPC’s document controller checks for, because tags are how their whole system files what you send.
The tags already exist in your equipment list, so the job is moving them without retyping.
Keep one authoritative equipment list. One spreadsheet, one row per tag, with the model, serial and line references beside it. Every tag list on every cover page gets built from this sheet and nowhere else.
Build the tag list with formulas, not paste. A filter or TEXTJOIN against the model number pulls every tag for that document into one cell or one column. Paste-as-values into the cover template is the fallback, and it’s also the step where staleness starts, because pasted values don’t know when the source changed.
Decide the layout rules once. One tag per row, or comma-separated in a block? What happens at the page boundary when the list is longer than the sheet? Write the rule down; improvising it per document is how the same customer gets three formats.
Watch the assemblies. Valve, actuator and positioner each carry their own tag and model. The assembly document has to list tags across all of them, with repeated model references handled sensibly rather than listed three times.
Where it breaks is change. The customer adds six tags in month four. Every cover page for every document touching that model is now wrong, and nothing in the spreadsheet method tells you which ones those are. You find out by re-deriving it, or by having a reviewer find it for you.
In DocBoss every document is linked to its equipment, so tag lists on cover pages come from that link instead of being typed: enter the equipment once and it reaches every cover page, index and book built from it. Cells expand to fit, lists print one value per row where that’s what the form wants, and a list too long for one sheet continues onto the next instead of truncating. Assembly documents carry every tag from every sub-line, with repeated model references grouped. And when the equipment changes mid-project, DocBoss flags every document whose references changed, so the forty-tag cover page can’t quietly go stale.
If your cover pages carry long tag lists, that’s the demo to ask for.
