There is a discussion about IDD reporting with IDMS/SQL https://communities.ca.com/thread/100564966 within this community - it also "morphs" into a discussion about using Culprit for IDD reporting and includes a link to some Culprit training - so there's lots of "meaty beaty big and bouncy" content for those interested in IDD reporting techniques.
Hope some enjoy this - cheers - GaryC
