Update Process
Purpose
In order to better understand the update rules maintenance, make yourself familiar with the underlying update mechanism.
Process
You load a request into the InfoCube (or into any other InfoProvider). For each existing key figure loaded into the InfoCube, the update mechanism calculates the characteristic values and puts the results into an intermediate buffer.
If more than one key figure is updated, each individual entry is then processed for a key figure, meaning that the value of the key figure is calculated initially and then all values of the characteristics. The values of other key figures are initially set to zero. All entries are thus processed specific to key figures one after another.
Entries that are identical in characteristic values, are aggregated for an entry in the buffer table. With the aid of the update routines, you do have the option, however, of using the function
Splitting Key Figures and, thereby, generating more than one entry from a single entry.The processed entries are updated in the data target by the internal table.
In the example graphic above, three records from the communication structure are updated that are processed one after another. The characteristic sales person does not exist in the InfoCube and is, therefore, not updated.
The characteristic values for the first key figure (profit) of the first record is calculated initially. The key figure value of the second key figure (number) of the first record is first set to zero.
In the next step, the characteristic values are calculated for the second key figure of the first record. Since the characteristic values for both key figures concur, they are aggregated.
The other records are processed in this way, one after the other. Since the characteristic sales person is not updated, the characteristic values for both key figures are the same in the first two records. These are consequently aggregated up to one record.
