Definition

The search depth of a precalculation defines the character in a table key up to which a precalculation is made. The function does not cover individual key fields, but uses the complete key for a preliminary structuring of a table.

For client-dependent tables, the client field is treated as a normal field; consequently its characters count towards the search depth.

Use

The search depth is used to specify the degree of preliminary structuring for a table. If the search depth is too deep, performance problems may be occur during the precalculation because the respective table is split up into too many parts. Consequently, you should rather choose a value that may be too low than a value that is too high and leads to extremely long runtimes for the precalculation.

When defining the search depth, keep in mind that it does not go very deep into selective key fields because otherwise (in the worst-case scenario) the table might be split up into individual records, which would again result in extremely long precalculation runtimes.

Dependencies

Example

Key field 1: 3 characters

Key field 2: 5 characters

Key field 3: 8 characters

Key structure for search depth 5 (X = characters of created key )

Key 1 Key 2 Key 3
| X X X | X X _ _ _ | _ _ _ _ _ _ _ _ |

Key structure for search depth 12 (X = characters of created key )

Key 1 Key 2 Key 3
| X X X | X X X X X | X X X X _ _ _ _ |
