What happens if UD is not performed for Skipped Lot?

[sp0123]

Dear Experts,

I have a query regarding the UD for skipped Lot. Due to the Dynamic Modification Rules, there are Inspection Lots which are getting skipped and directly posted to Unrestricted Stock. What will happen if I don't perform UD for those skipped lot? Will this affect in any way?

Thanks in advance

Open inspection lots can interfere with monthly closing.

Stats for the Q-info system and data warehouses are updated when UDs are made so any qty postings as the relate to quality may not show up in your stats depending on how and what you do.

Depending on your downstream processes, you might have problems if you use any functionality the checks on UD codes. For instance, COA profiles, batch derivation, batch determination in warehouse picking, or IM picking strategies.

Most places use the UD codes to assign Q-scores. If no UD, no quality score calculations are done.

If you use any Q-levels, DMR's with these lots, there is usually no update to the quality levels.

The lots will continue to build and clutter up your worklists because they will show as open lots. You'd have to implement a filter or layout to exclude these which, depending on how you use skip lots, and for what, might hide skip lots you SHOULD see.

Basically, its recommended you process these using the batch job for skip lots. Not doing them potentially reduces your ability for other functionalities. You may not use a specific functionality now, but will want to later and then you'll need to this anyway and your won't be able to apply any historical data cause you won't have it.

Hello Craig,

That was a detailed explanation and gives more clarity regarding the need for closure of the skip lots. I have a question regarding the background job. Is it mandatory to schedule the Job planning for auto usage decision in Transaction QA17 ? Or would be sufficient to maintain the Waiting time for Skip lot in QM Plant Dependent settings so that we can avoid to maintain in QA17? Could you please give your inputs

Thank you

Best Regards

Hari

You don't need to schedule the job via QA17, it can be scheduled by your BASIS team with whatever tools they use to set up batch jobs.

The waiting time is independent of when or how often you run the batch job. It needs to be defined. The wait times mean that even if the batch job runs, the lot won't be processed unless the lot is at least as old as the wait time. Sometimes the stock is set up to go directly to unrestricted, sometimes it's held in QI. Depends on the material and the level of risk but the inspec lot won't be processed.

The purpose of the wait time is to allow you to "grab" skip lots. Skip lots are primarily used in two places. Goods receipts from vendors and in manufacturing. For receipts from vendors we often only inspect a few shipments/per material a year. Sometimes only once a year.

In manufacturing, especially with floor based MES systems, we often receipt every pallet of material. Or we receipt in by shift. Often times they only want to inspect samples from every third or fifth pallet, or the last of receipt from the last shift that reported stock.

For purchased material, we might normally skip the inspection but if while putting it away, the warehouse people might see something amiss about it. If the SKIP lot has not been processed yet, they can go to the insp lot and make ANY change in the lot, (like adding a short text to a test, "please verify color"), and the lot loses it's SKIP status and now must be manually processed like a regular lot. This allows the stock to remain in QI (if it was posted to QI), or to allow it to be moved from unrestricted to blocked via the UD if you decide its bad material.

For manufactured material, if you test the 3 pallet and it passes, but then test the 6th pallet and it fails, you want to grab the skip lots for pallets 4 and 5 and test them. That allows you to identify exactly where the mfg process went off the rails.

If the SKIP lots were all processed immediately, you would never be able to do this. With a wait time of say 12 or 24 hrs, you have at least that long to grab these lots and use them for testing. With a wait time of 12 hrs, if my batch job runs once a shift, (every 8 hrs) you have the potential of having the skip lots available for 12-20 hrs depending on actual timing.

Determining how often to run the batch job for skips, and what your wait time should be is totally dependent on your business and the speed vs. risk analysis of your process.
