The below gives an idea of what solutions can be proposed for Data Conversion.

Base assumptions

  1. Data Conversion approach is well defined and understood by all parties involved
  2. Mapping between legacy data and SAP structures has been completed
  3. Sample files are ready for performing unit testing
  4. One set of source structures is used1
  5. Analysis and Design correspond to the time required for reviewing the approach/mapping and proposing a solution
  6. Construction is the time necessary to build the LSMW object
  7. Unit Testing corresponds to the time necessary to load the set of sample files into the development client

Complexity factors

The complexity of a Data Conversion object depends on multiple criteria whose most important are:

  1. Data quality of source files
  2. Number of source files
  3. Existence of a standard LSMW method/object, BAPI or ALE message type
  4. Complexity of the mapping between the legacy data structures and the SAP data structures (complex algorithms…)

Estimation metrics

Estimation metrics are usually based on complexity factors (Low , Medium, High).
