Assumptions of 100 jobs
1. The # of jobs with High complexity - 20
2. The # of jobs with Medium complexity – 30
3. The # of jobs with Low complexity – 50
1. Following are the Key Assumptions for approach - 1
- Legacy System owners / Legacy IT team are responsible for data profiling and data cleansing on the source legacy systems. Cleansed source / legacy data is provided as input to the data conversion team.
- For LSE / Non SAP legacy systems – Legacy IT team to cleanse, extract the required legacy data and send in ASCII or Desired code page file format ( multi-lingual support) as input data to technical conversion team.
- BODS ETL Technical team to decide the best approach of data extraction, data transformation, data load during the design phase.
Sr. No | Tasks to be performed | Time required for Low complexity | Time required for Medium complexity (includes business logic) | Time required for High complexity (includes complex business logic , several lookups etc) |
1 | Preparation of ETL Mapping Sheet | 2 days/job | 3 days/job | 5 days/job |
2 | ETL Job Design and Development | |||
3 | ETL Job Testing with test case scenario | |||
4 | Migration one environment to other (import and export) | |||
| Time required for 100 jobs | 2 * 50 = 100 Days | 3 * 30 = 90 days | 5 * 20 = 100 days |
2. Following are the Key Assumptions for approach – 2 (Extracting Data directly from SAP and Non SAP Source and loading into SAP – BW)
- Connecting to Non-SAP and SAP source Directly
- Includes cleaning, profiling and error validations
- Routing data directly to SAP-BW
- BODS used to communicate with SAP and Non SAP Source and loading directly into SAP – BW Target
- Develop some standard job for validation and reuse for other objects as well
