You cannot change the assignment; formula is recipe-dependent

What causes this issue?

The usage of dependent formulas has been activated in Customizing for
the recipe type of the recipe you selected (see
<DS:DE.PVS_REMTCTRL_FORM>Formula assign.</> indicator). The formula was
created when the recipe was created and thus is an integral part of the
recipe. You cannot change the assignment.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Make the required changes in the formula assigned. The formula is only
used in the current recipe.
