OK - here is the weird issue with this.....If you print in Graphics mode, it does it correctly (multiple BOMS)....If you print in text mode, it does not.

Just found out that BKBMB.run is not printing out vendors even if flag is set to Y.   Upon further testing, neither is t6bmb.run...
 
On a possibly related note, I am finding that when I go into IN-B it will show a primary vendor, but when I click on vendors none are listed.  I click add and then it auto populates with the primary vendor.  After that a vendor record shows in bksbvend for the part that was not there before I "added" the vendor in IN-B.  And now vendor shows up on graphics and text mode printouts of t6bmb.run.  Boy, I'd hate to have to go through my whole inventory reentering all of the vendors...

The Vendors used to be stored in MTICMSTR and there was a limit of 3.  Many many years ago they were moved to BKSBVEND which stores vendor and vendor part number but hte primary vendor is vendor #1 in MTICMSTR.  UT-A program SBUTIL will move vendors in MTOCMSTR to the BKSBVEND file.
