While performing a test upload for the 2.8.0 taxonomy, we constantly receive a formula assertion warning as below [BV1439];[(t: S.17.01.01.01, r: R0160, c: C0030) reported as {$v0} = sum((t: S.19.01.01.04, r: R0260, c: C0360, z: Z0001, filter: [s2c_dim:BL] = [s2c_LB:x52]) reported as {$v1})]; The item "Gross - Total" reported for Income protection insurance in S.17.01 should be equal to "Total" item reported for Year end (discounted data) reported in S.19.01. This applies for all LoB and for S.19.01.01.10 and S.19.01.01.16 even when S.17.01.01.01 items reconcile with the amount of S.19 Can you please elaborate further on the issue? Can this be solved or is a known error in the new taxonomy?
