Cast error on /ERP/CHRTACCT dimension view

Hi,

while navigation /ERP/CHRTACCT in S4HANA BPC, it leads to below error. Did anyone faced and resolved before.

During a 'CAST' operation ('?=' oder 'MOVE ? TO')a type conflict occurred. The source type '\CLASS=CL_RSDMDM_OBJ_VIOBJ' is not compatible for assigning with the target type '\CLASS=CL_RSDMDM_OBJ_CHA_EXT'.; MsgClass:
