ASL data and lead times(purchasing and inventory)

Hi All,

I had a couple of questions.

I see that in our system there are lot of records around 600k. I was just wondering how the ASL entries are populated,obviously it should be thru some process/program, what is that program/process ?

Also in the ASCP plan options, I see under the constraints tab, the setting "Enforce Purchasing lead time constraints" is enabled. So I was checking under the approved supplier list => suppliers => attribute, there is no purchasing lead time attribute specified.

However I also see that at the item level , in the lead times tab, there is lead time specified.
