SAP Business One HANA & Power BI Optimization Guide

Leveraging SAP Business One on HANA requires understanding SAP's underlying DB schemas (OINV, INV1, ORDR, RDR1).

Best Practices for Custom Views

Avoid querying transaction tables directly in Power BI; create optimized HANA Calculation Views or SQL Views.
Use LEFT JOIN on document lines with DocEntry and LineNum composite keys.
Filter data at the database layer using parameters rather than loading raw tables into memory.

SELECT 
    T0."DocNum", 
    T0."DocDate", 
    T0."CardName", 
    T1."ItemCode", 
    T1."LineTotal"
FROM OINV T0
INNER JOIN INV1 T1 ON T0."DocEntry" = T1."DocEntry"
WHERE T0."DocDate" >= ADD_YEARS(CURRENT_DATE, -1);
