Alternate Methods and Case E10

So I've been having trouble with alternate methods and with Get Details grabbing the wrong methods for configured parts. We have only one group of products that another site needs to use these alternate methods.

Our Carlisle plant's MOMs have been getting a mixture of Lubbock (primary) and Carlisle (alternate) methods.

I was sifting through the PartRev table and notice I have a mixture of case as in:

Company Part Rev Alternate Method Site

BG  309-062 A10 Carlisle CARLISLE

BG 309-064 A10 Carlisle CARLISLE

BG 310-039 A10 CARLISLE CARLISLE

BG 310-220 A10 CARLISLE CARLISLE

I recall seeing case problems mentioned. I thought I'd just update those records with the right case, but it's a key field so it won't let me.

Before I go ripping things out of the part rev, boo, and bom--does this matter? What will I kill if I remove a PartRev record and put it back with the new record?

Thanks,

Joe
