Key points:
1. Why we have only 16 Dimension tables in a cube. Is there any resin’s it a limitation?
Answer
Database Table can have maximum of 16 key fields only. So we
Cannot create more than 16 dimensions. Three is sap
Provided and we create only 13 dimensions.
There are no limits to the number of Info Objects, number of Info Cubes, or the
number of reports per Info Cube.
The system administrator can create 13 dimension tables in addition to the
dimensions for time,
Packet ID and measure of unit for each Info Cube.
Number of characteristics in all dimension tables:
Each of the dimension tables can have 248 Info Objects(chars), computed by 255
– 6 (no access to these Fields) –1 (Dimension ID) to obtain 248. For
performance reasons we recommend a maximum of 16
Info Objects per dimension.
A fact table can have up to 233 key figures, computed by 255 – 6 (no access to
these fields) – 16
(Dimensions) to obtain 233.
