Tables missing in BQ1

Dear all, We have an serious problem to solve, we can not work in an environment because the system doesn't find a table (/1CPMB/LZDQMO2 -> dimension Account) and is returning a dump with this runtime error: "DBIF_RSQL_TABLE_UNKNOWN" for each activity performed in the environment.

Could anybody tell me if there is any program to regenerate the runtime object and the database object for this table (similar to SE14) or any functionality at BPC dimension level?

Thank you in advance.

Best regards,

Adolfo
