ANA_STRUCT_GEN_ALM - Create DataSource for Analysis Structure

In this activity, you create a transaction DataSource, which you use to analyze data from Asset/Liability Management (ALM). During the generation process, the system automatically finds the analysis structure that is currently active for the client in which you are working. This analysis structure defines the characteristics that the system uses as the basis for creating a transfer structure.

The DataSource must have a unique technical name. The naming convention for the DataSource is as follows:

• Prefix 1_BA_SEM_ALM

• Name and client of the SAP system, for example: system BNK, client 100

• Name of the analysis structure, for example: BANK

• Unique four-digit ID, for example: 0001

This means that the first DataSource based on the analysis structure BANK in client 100 in the system BNK would generate the DataSource name 1_BA_SEM_ALMBNK100BANK0001.

1. Choose Save.Note that you cannot change the standard name by changing the standard name of the template. Doing so would cause an error.
2. Enter the required data, and save your entries.
3. Set the Selection indicator for characteristics from the SAP Business Information Warehouse (BW) for the selection criteria that are needed for the data transfer. The DataSource should have at least the characteristic SAVE_ID.

The key figures listed in the selection screen do not relate to the analysis structure. Instead, they are based only on the requirements of the ALM evaluations. You do not need to select any key figures here because the OLTP system ignores your selection, even if you select the key figures in the BW system itself.

If required, you can hide fields in the DataSource. However, this is not relevant for ALM.

1. Save your data.

Technical information

You can use only the SAVE_ID characteristic, and the characteristics that are part of the analysis structure (OLTP) as selection criteria for the selection of data records from InfoPackages. If you use DataSources that were generated generically, then you can select any characteristics values or key figure values from InfoPackages. This enables you to filter information that was processed by the OLTP system. Although this applies for ALM DataSources, it does not work in exactly the same way. ALM data is very complex, and can be extracted from the OLTP system only after it has been saved, and a corresponding SAVE_ID key has been created. However, this saved version of the ALM data is not in the format that is required for data extraction. Instead, the system saves the data in a compressed format, which allows the data to be displayed in the SAP List Viewer (ALV). Parameters such as the currency, maturity band, interest/capital commitment, and the evaluation type are the basis for this. The data is extracted to BW as a batch job, during which the user does not have to do anything. For this reason, the system has to generate all conceivable combinations of parameters to ensure that all the ALM data is available that is required for the extraction process. In the generation process, technical problems can occur when the data that is to be extracted is defined. For this reason, there is a restriction on which criteria are available for the InfoPackages.
