Skip lot in Modification rule

[former_member407544]

Hi,

    Can someone please explain the rule in the attached. We are expecting the quality level to change after 364 days to stage 70 but we are receiving in lots and the stage is not switching and staying at 60. Is there something i am missing here as to why it is not switching.

The idea was that on or after 364 days the next lot in would open for full inspection and this would be required every year. But it appears lots after 364 are not opening?

Regards,

Anthony.

First off.. I see no stage 70 in your screen print you provided.

Please read the F1 help for the field Max. Skip duration.

See the the example, in particular, Example 2 which I've pasted below:

Example 2

Dynamic modification rule
Stage 1:    Initial inspection
stage/Inspect
            Accepted (OK)                  Rejected (Not OK)
            Number of inspections: 1       Number of rejections: 1
            New inspection stage:  2       New inspection stage : 1

Stage 2:    Skip
            Accepted (OK)                  Rejected (Not OK)
            Number of skips : 32600        Number of rejections  : 1
            max. skip duration : 30 Tage   New inspection stages : 1
            New inspection stages : 3

Stage 3:    Skip
            Accepted (OK)                  Rejected (Not OK)
            Number of skips   : 32600      Number of rejections: 1
            max. skip duration  : 30 Tage  New inspection stage: 1

Once you've read that and setup and experimented wiht the above example settings, let us know if you have specific questions.

Also, please review this thread very carefully as well.

HI Craig,

See attached mod rule with stage 70. I have read above first in the help file  but it is not very clear to me. We have the stage 60 ruled to move to 70 after 364 days but it doesn't appear to be moving? Based on above should stage 70 be a skip stage as well?

[former_member42743]

yes. that's my understanding.

HI Craig,  I am still testing this but are we are still having issues. I am been told that the quality level is gets updated upon receipt and on making the UD. When this happens the date of last inspection in the quality level updates to when the latest lot is receipted or the last UD completed.

Problem is i am been told that the max skip days is calculated based on the current date minus the date of last inspection. If this is the case we will never switch from stage 60 to 70 unless we have done no UDs or not received in any batches in 365 days? Is this correct?

Is the number of skip days calculated abased on the current date minus the date of last inspection in the quality level?

Help "The date of the last inspection is overwritten with the current date on which an inspection is planned or performed both when an inspection lot is created and when the usage decision is made. An entry is made in the field when a quality level is created for the first time even in the event of a skip."

Regards,

Anthony.

No.. the quality level gets update either at the GR or the UD.  Not both. 

The date may get update at both times but not the quality level.  (I can't say I've really noticed that about the dates one way or the other).  The date is also update when the quality level is created for the first time.

There are two values that interact.

Maximum number of skips:

Maximum skip duration:

Did you test with the settings I posted above?  Obviously changing max skip duration to one day for testing, (which really takes two days to test).

Thanks Craig. That's what i was thinking also but getting conflicting info back on this side. I have set up a simplified version and waiting for it to run for the 12 / 13 days and hope to see a flip so i have something to go back to our support with.

It worked when i had it on only 2 days but i have been told to test longer due to the info i got back above. So i am receiving in 1 lot a day accepting the UD and recording all QL changes. Hopefully it flips on day 12/13. I will get back to you. Thanks for the response.

Regards,

Anthony.

So it appears that this mod rule isn't switching for me. Its been running over 12 days and the rule is staying at stage 20. IT has put the reason down to below so looks like we need coding. Thanks for the help.

The system considers the 'Date of last Inspection' (field QDQL-DATLPRUEF) when calculating maximum skip duration. This field is not only updated when creating a new inspection lot but at the time of usage decision as well. E.g. using 20 days as maximum skip duration the skip inspection stage is only changed when neither new inspection lot has been created nor usage decision has been made in the last 20 days. This standard system behavior is documented in the F1 help of field 'Date of last Inspection' (QL-DATLPRUEF): "The date of the last inspection is overwritten with the current date on which an inspection is planned or performed both when an inspection lot is created and when the usage decision is made..."
