SyteLine APS error 30012: what to check before rerunning
syteline aps error 30012
Also searched as
- SyteLine APS scheduling failed
- APS planning service error SyteLine
- SyteLine APS sync error
Short answer
APS errors in SyteLine generally come from three places: the APS planning service itself, the data sync between SyteLine and the APS database, or bad source data such as a missing routing or calendar. I could not confirm an official definition for code 30012, so this page gives the diagnosis order that isolates the layer before you rerun the schedule.
Applies to: SyteLine 9.x and CloudSuite Industrial 10.x with Infor APS (Advanced Planning and Scheduling)
Isolate the failing layer
- 1Record the full message, who ran APS, the planning site and the time. Note whether this was an interactive or scheduled run.
- 2Confirm the APS services are running on the app or planning server and that the account they run under is valid and not expired.
- 3Check that the SyteLine to APS sync tasks ran without error. Failed syncs leave APS with stale or partial data.
- 4Review the sync and APS logs for the first error in the chain, not the last one.
- 5Validate source data for the items in the failing run: item has a routing, work centers have a calendar and capacity, and no negative or zero lot sizes.
- 6Check SQL Server for blocking or timeouts during the run, since APS reads and writes heavily.
- 7Rerun on a small subset (one item family) to see if it is data-specific.
- 8Only after the cause is fixed, run the full sync and schedule again, and compare the planned orders to expectations.
How APS fits with SyteLine
APS works on its own planning data set. SyteLine pushes demand, supply, items, routings and calendars into it through sync processes, APS computes the plan or schedule, and results flow back as planned orders and dates. An error can occur at the push, in the calculation, or in the return.
That is why rerunning the schedule over and over rarely helps: if the sync failed upstream, APS is calculating from bad data and will fail the same way.
Data problems that stop a schedule
The most frequent root causes are structural: an item with a routing referencing a deleted work center, a work center with no calendar, a calendar that ends before the horizon, circular or unusually deep BOM structures, and jobs with invalid dates. A clean-up pass on these often removes the error.
Custom fields or modifications that write bad values into planning tables can also cause it. If the error started after a customization or upgrade, diff what changed.
-- Example read-only checks (adjust table names to your schema) -- Items with a routing referencing a work center that no longer exists -- Work centers without a calendar entry that covers the horizon -- Jobs with release date after due date
Services, accounts and performance
If the services were restarted after a password change or server patch, they may be running under a stale account. Check the service logon, the database permissions, and whether antivirus or a firewall change blocks the planning server from reaching SQL.
Long runs can also hit timeouts. See the APS performance tuning page for index and parameter guidance, and avoid running a full regeneration during peak transaction hours.

SyteLine MRP vs APS Assessment
Answer ten questions about capacity, routing complexity and planning cadence to see whether SyteLine MRP is enough or an APS tool is worth evaluating.
Common pitfalls
- !Rerunning the full schedule repeatedly without checking the sync.
- !Searching for the code alone and applying an unrelated fix.
- !Changing planning parameters while the underlying data problem remains.
- !Running APS during heavy order entry and blaming the software for blocking.
- !Not testing the fix on a small item subset first.
How an ERP-grounded AI assistant handles this
SyteRay can read your SyteLine and planning tables to list the items, routings and work centers that violate the checks above, and show the query behind each finding. That turns an hour of manual SQL into a review list. It is read-only by default; any corrections go through your normal change process.
Frequently asked questions
What does APS error 30012 mean in SyteLine?
I could not find a reliable official definition. Treat it as an APS failure and isolate the layer: service, SyteLine to APS sync, or source data. The full message text and the first error in the logs are more informative than the number.
Should I rerun the APS schedule right away?
No. Fix the cause first. If the sync failed or the data is invalid, a rerun produces the same error or a misleading plan. Verify sync success and run a small subset first.
Can bad routing data cause an APS failure?
Yes. Missing work centers, work centers without calendars, or invalid operation data are common causes. Validate routings and calendars for the items involved before rerunning.
How is this different from MRP regeneration failing?
MRP failures originate in the standard planning process, while APS failures often involve the separate APS service and sync. The related MRP page covers the former. Some checks overlap, especially data quality and SQL contention.

Troubleshooting SyteLine MRP and APS regeneration that fails or hangs
A SyteLine MRP or APS run that fails to complete, hangs indefinitely, or errors partway through is most often caused by data integrity problems (a BOM loop, an item with an invalid lead time or missing routing), a scheduling engine (APS) process that is stuck or resource-starved, or a concurrent MRP run conflict. Check the MRP/APS log first for the specific item or job it stopped on before assuming it is a system capacity issue.
AdvancedHow to Tune APS Finite Scheduling Performance in SyteLine
A slow APS run in SyteLine is almost always caused by an oversized planning horizon, too many resources marked as constrained, or an unindexed staging table, rather than the scheduling algorithm itself. Trimming the horizon, scoping constrained resource groups, and running incremental instead of full regenerative schedules typically cuts run time dramatically.
How-toHow to Run MRP in SyteLine
MRP in SyteLine runs from Planning > MRP Processing as either a full Regenerative run or a Net Change run against demand from customer orders, forecasts, and safety stock; results appear as planned orders and Action Messages in the Planner Workbench.
How-toSyteLine Freezing for Everyone: Find the SQL Head Blocker
When several SyteLine users freeze at once, a single session holding locks and blocking a chain of others is a common cause. Query sys.dm_exec_requests for blocking_session_id, walk the chain to the head blocker, read its statement and open transaction, and decide whether to wait, fix the caller, or end the session.
Error fixFixing SyteLine's 'Object reference not set to an instance of an object' error
This is a generic .NET NullReferenceException surfacing through the SyteLine IDO Runtime, not a SyteLine-specific error code. It almost always means a form, script or IDO method referenced a field, row or object that came back null, usually after a customization, a missing related record, or a view/IDO method call before the form finished loading. Turn on detailed client logging and check the most recent customization or form event first.
Error fixDiagnosing and fixing SyteLine session timeout errors
SyteLine session timeouts come from one of three independent layers: the IDO Data Service session timeout on the app server, the IIS/application pool idle timeout for the web (Mongoose Web) client, or a load balancer/proxy idle timeout in front of a CloudSuite hosted environment. Fixing the wrong layer is the most common mistake - you need to identify which layer is actually expiring the session before changing anything.
