Once data-warehouse is built and BI reports Needs to created. Then requirement gathering phase HLD High level design and LLD Low Level design are made.
Using HLD and LLD BI semantic layer is built in SAP BO its called Universe, in IBM Cognos using framework manager create Framework old version called catalogue, In Micro strategy its called project.
Once this semantic layer is built according to report data SQL requirements.
Note: Using semantic layer saves lot of time in adjustment of changed Business Logic in future change requests.
Real issues Example: Problems in semantic Layer creation like in SAP BO: Read

There are sets of reporting tool to choose from Like in IBM Cognos choose from Query Studio, Report Studio, Event Studio, Analysis Studio, Metric Studio.
2. Tool modification using SDK features are not enough then need to modify using Java/.net of VC++ API. At html level using AJAX javascript API or integrating with 3rd party API.
3. Report level macros/API for better UI.
4. Most important is data requirement my require Coding procedure at database or consolidations of various databases. Join Excel data with RDBMS and unstructured data using report level features. Data features may be more complex than UI.
