Things to consider in BW implementation for a Retail Industry.
1. Use 0ARTICLE instead of 0MATERIAL (Will get delta issue for 0MATERIAL_ATTR and 0MATERIAL_TEXT, so use Article datasources)
2. Select the Industry sector Retail in ECC before filling setup table for Inventory and Purchase data.
3. Select a small amount of data in report level , specially at the time of Inventory report. ( If possible schedule the report before use for big data).
4. Have to use carefully , Article Pricing grade in Inventory report.
