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.
check you formula item. even i encoded this issue.
i created an new formula item which is not an CW item BOM to it. then this issue got resolved.

check you formula item and co-product item. try to create new formula and co-product item with you CW and try the same.
try to set Planning Formula for co-product (Item coverage form, general tab)
