Inspection Severity 002 / AQL 0,150 not in sampling scheme 220

Dear all experts,

I am trying to use DMR and sampling scheme and sampling procedure to determine the sampling size that to be inspected with below scenario.

1) 1st incoming

- 0010 visual (non-skip, S3 - AQL 0.15)

2) 2nd incoming, if pass the first incoming

- 0010 visual (non-skip, S3 - AQL 0.65)

In my sampling scheme, i have set as followed:-

Severity Shortext AQL Value 2 Reduced inspection 0.65 4 Normal Inspection 0.15

in DMR, ive set as followed

Stage Severity Skip initial Stage Shortext 1 4 X Normal Inspection 2 2 Reduced Inspection

when i try to link the relationship in QDB1, it shown below error:-

"Inspection Severity 002 / AQL 0,150 not in sampling scheme 220"

i have no problem to link if i set the AQL value name as 0.15 for both severity 4 and 2 in sampling scheme.

pls advise, what setting is missing / or why i cannot set different AQL in sampling scheme?

thanks in advance.
