DMR at Inspection Points

[sourabh_maheshwari2]

Hello Experts,

I want to use DMR with Inspection Points.

In the master recipe, I have currently assigned Inspection Point 150 and set Dynamic Modification at Characteristic Level.

i have also assigned the DMR to the characteristics in the recipe.

However, when the process order is released and the inspection points are created, the DMR does not work.

For example,

I have assigned a DMR (say D1) to characteristic C1 for which results will be recorded alternately (1 recording - 1 skip - 1 recording so forth)

3 inspection points get created on the order release.

My expectation was :

1st IP : C1 - record results

2nd IP : C1 - skip

3rd IP : C1 - record results

However, current situation is :

1st IP : C1 - record results

2nd IP : C1 - record results

3rd IP : C1 - record results

When i release a second order, result is :

1st IP : C1 - skip

2nd IP : C1 - skip

3rd IP : C1 - skip

DMR is set at Lot Creation.

I understand that the Quality Level is managed at Inspection Lot level, and hence this behavior of the system.

But, what can I do to achieve the desired result?

Hello fire.fighter

I am using "At Lot Creation" since I was expecting DMR to change at every Inspection Point

But the quality level does not get created

I did think to create a copy of FM QAPP_CUST_IP_CREATE and modify it to create the characteristic level and update it at every inspection point creation.

However, I realized it will induce inconsistencies at 2 points :

1) Stage will change as soon as lot is created

2) Stage will change at UD

This will be a problem since even if I reverse the stage change after UD using Follow-up functions, it would be hard to limit this follow-up action only to required material-plant combination (as not all characteristics would be using skip functionality).

Yes. Whether you use lot creation or at UD, you have the issue of not having the DMR you want in some situations.

This is why, that whenever a DMR failure happens, you MUST have a quality analyst examine the impact and make appropriate corrections to quality levels and existing inspection lots as necessary. It really is quite impossible to 100% totally automate this for all situations and very difficult to "undo" DMR's and change existing lot statuses.

This is why a quality analyst needs to investigate and SOP's need to be written in general terms to allow the analyst to make determinations and changes appropriate. Trying to write rules for every potential situation will get a company into trouble.

I still don't know why your DMR isn't working without using physical samples. I've rarely used physical samples with DMR. But I have done it both ways.

Have you tried setting the DMR to "At lot creation" instead of "At UD?"

In case i do not use a SDP, then quality level at characteristic level is not getting created

is there some setting I am missing?

I noticed that I had assigned sample drawing procedure in the master recipe when i was using inspection point (physical sample).

I changed that to 150 and forgot to delete the sample drawing procedure.

Hence, the skip was still working at inspection point.

As soon as I removed the sample drawing procedure, the skip does not work at all.

If I now try to assign the SDP at the master recipe, i get the error message "

Sample-drawing procedure only allowed for insp. point type "phys. sample"

It seems that DMR is supposed to work with inspection points physical sample only.

[former_member42743]

If you want to use sample-drawing procedures you must use physical samples.

But you shouldn't need to use a sample-drawing procedure to use DMR.

[sourabh_maheshwari2]

yes, quality level is at characteristic level

[former_member42743]

Is this for an 03 or 04 lot?

Craig

[sourabh_maheshwari2]

it is for 03 IL

Hello Craig,

Yes, we are using FM QAPP_CUST_IP_CREATE for automatic creation of the inspection points.

I deactivated the same, and then tested by creating 1 inspection point at a time and valuating it and then creating the next.

However, the behavior remains the same. There is no stage change in the quality level and skip does not happen.

[former_member42743]

Do you have a quality level at the characteristic level?

Craig

If your inspection points are all created at the time of the inspection lot creation, then that is being done by an FM that was configured as part of the inspection point identifier in config. That's custom. SAP only provides and example FM to be used as a template to create your own. My guess is your FM doesn't look at DMR logic.

Try using the standard SAP delivered Free inspection points which shouldn't have your FM to pre-create the inspection points. Do the first inspection point and valuate it. Save it.

Then go in click on new inspection point and the second one created I would think should now be a skip one now.

If that works, you'll need to have a programmer review your FM for creating the inspection points and incorporate logic to follow your DMR's.
