• Issue is caused by memory exhaustion due to a large dataset.
• Source data scope can rapidly expand to generate very large volumes of data if multiple dimensions exist, even if the individual members in each dimension are small for example:
• Project * Company * Fiscal_Year * Journal * Product * Account * Currency * Code * Entity = 3 * 3 * 3 * 404 * 25 * 278 * 4 * 1116 * 13 = 4.39944E+12.
• Data actions that are not correctly limited in such cases will cause an excessively large load from backend and result in the error "An unexpected technical error occurred and has been logged".

• Effective use of MEMBERSET statements defined in advanced data actions are recommended to filter source data to be copied to only include dimension members filtered by MEMBERSET.
• This reduces the usage of your system capacity, like memory allocation or peak memory, and thus helps to enhance system performance.
• We recommend you Define as many MEMBERSET statement as possible.
