SKIPCHECK
During consolidations, TM1 uses a sparse consolidation algorithm to skip over cells that contain zero or are empty. This algorithm speeds up consolidation calculations in cubes that are highly sparse. A sparse cube is a cube in which the number of populated cells as a percentage of total cells is low.
When consolidating data in cubes that have rules defined, TM1 turns off this sparse consolidation algorithm because one or more empty cells may in fact be calculated by a rule. (Skipping rules-calculated cells will cause consolidated totals to be incorrect). When the sparse consolidation algorithm is turned off, every cell is checked for a value during consolidation. This can slow down calculations in cubes that are very large and sparse.
SKIPCHECK;
If your rule uses a FEEDSTRINGS statement, the SKIPCHECK statement should be the second statement in your rule. If your rule does not use a FEEDSTRINGS statement, the SKIPCHECK statement should be the first statement in your rule.
When you use SKIPCHECK to restore sparse consolidation, you must also ensure that your rule includes a FEEDERS declaration and that all rules-derived cells are identified by feeder statements.
For a complete discussion of TM1 rules, including sparse consolidation and the creation of feeders, please refer to TM1 Rules.
