Can I trigger a form to fire after 50% of a production run is completed?

No — it isn't currently possible to trigger a form based on a percentage of a production run using a standard offset. Triggers in OFS-Flow work on absolute values: specific time durations, total unit counts, or machine state changes.

Because every production run varies in size, a fixed unit offset can't dynamically calculate the halfway point for every job.

Workarounds

• Manual trigger — operators can manually raise the form from the console once they judge the run to be roughly halfway complete.
• Rated speed unit trigger — if your jobs have consistent hourly requirements, set a trigger based on the product's rated speed. For example, a job that's typically 1,000 units can use an offset and repeat of 500 units to capture a mid-point check.

Setting up a rated speed unit trigger

Step 1 — Open the job trigger

• In the Triggers tab, click the job trigger and click the + button.

Step 2 — Turn on the conditional expression

• Click the Conditional Expression tab and toggle it on.

Step 3 — Enter the expression

• Use an expression along these lines:

jobmeta["ratedSpeed"]==1000

Step 4 — Turn on Repeat

• In the General tab, toggle on Repeat.

Step 5 — Set the unit count

• Enter the number of units, e.g. 500.

Step 6 — Select the unit type

• Select the Units, e.g. In.

Step 7 — Select the lines

• Select which lines this trigger applies to.

Step 8 — Save

• Click Update, then Save.
