when you run the APP, you need to give the head office vendor number.
Please see the below ..
vendor 2000295 is the head office, 2000175/2000156 are the branches.
2000195 is the alternate payee
posted 1 invoice each to the branch offices.
ran F110 for 2000295 and below are the screenshots of F110 and check (only one check created)
Hope this helps. if not, please let me know
Thanks
