I encountered this error when I simulate master planning for a co-product item from a formula item. I have for example a Sales Order for a co-product which is Product A of 10 pcs. then I run Master scheduling to see if a planned Batch Order will be generated, but I came along with this error.
“Coverage Failed for co-product A: no related formula version found. Coverage planning item Product A has been cancelled”.
Thanks and best regards.
