DROP TABLE--`, `OR 1=1--`) +6. **Performance:** EXECUTE IMMEDIATE bypasses statement cache - minimize usage +7. **Error Handling:** Add meaningful error messages with SIGNAL +8. **Documentation:** Comment why dynamic SQL is necessary + +**Anti-Patterns to Avoid:** + +❌ **Concatenating complex filter ranges:** +```sql +-- BAD: Hard to maintain and validate +lv_sql = lv_sql || ' AND material IN (' || :it_materials || ')';

If table name is from limited set (e.g., 3 year-tables), consider factory pattern with 3 static AMDP methods instead. + +--- + +## Program Optimization Checklist + +When optimizing existing ABAP programs with AMDP, follow this systematic approach: + +### Pre-Optimization (Mandatory) + +✅ **1. Backup Original Program** +```abap +SE38 → Copy original program to _OLD version +Create transport with backup +Test restoration procedure +``` + +✅ **2. Establish Baseline Metrics** +- Runtime: ST12 (Single Transaction Analysis) +- Memory: ST22 memory snapshots +- SQL stats: ST05 trace (count SELECT statements) +- Document typical selection criteria and expected volumes + +### During Optimization - 7 Key Techniques + +#### 1. Replace Loops with Database Operations + +❌ **N+1 Query Anti-Pattern:** +```abap +SELECT * FROM bkpf INTO TABLE lt_bkpf WHERE ... +LOOP AT lt_bkpf INTO ls_bkpf. + SELECT SINGLE * FROM bseg WHERE bukrs = ls_bkpf-bukrs + AND belnr = ls_bkpf-belnr. + " 1000 documents = 1000 SELECTs +ENDLOOP. +``` + +✅ **Optimized with JOIN:** +```abap +SELECT a~bukrs, a~belnr, a~bldat, b~wrbtr, b~dmbtr + FROM bkpf AS a + INNER JOIN bseg AS b ON a~bukrs = b~bukrs AND a~belnr = b~belnr + WHERE a~bukrs IN @s_bukrs + INTO TABLE @DATA(lt_combined). +" 1 SELECT replaces 1000+ (500x improvement) +``` + +#### 2. Create CDS Views for Complex Joins + +Use CDS when: +- Same join pattern used multiple times +- Calculated fields needed (currency conversion, date calculations) +- Authorization checks at database level +- Virtual fields (CASE statements) + +**Example:** +```abap +@AbapCatalog.sqlViewName: 'ZV_VAT_HEADER' +define view ZI_VAT_HEADER as select from bkpf + association [0..1] to bset as _Vat on $projection.Bukrs = _Vat.bukrs +{ + key bukrs, key belnr, key gjahr, + bldat, budat, waers, + _Vat.mwskz, _Vat.fwbas, _Vat.hwbas, + // Virtual field + case _Vat.shkzg + when 'S' then _Vat.fwbas * -1 + else _Vat.fwbas + end as FwbasWithSign +} +where bukrs in $parameters.p_bukrs +``` + +#### 3. Use AMDP for HANA-Specific Operations + +**Use AMDP for:** +- Complex aggregations (GROUP BY with multiple levels) +- Window functions (ROW_NUMBER, RANK, LAG/LEAD) +- Recursive queries (BOM explosion, hierarchy) +- Large-scale set operations (UNION, INTERSECT) +- Multi-source data consolidation (13+ CTE patterns) + +**Don't use AMDP for:** +- Simple SELECTs (use ABAP SQL) +- Complex business logic with many IF/CASE (keep in ABAP) +- Authorization checks (use ABAP CDS) +- User interactions (messages, F4 help) + +#### 4. Eliminate Redundant SELECT Statements + +✅ **Use HASHED tables for lookups:** +```abap +" O(1) constant-time lookup instead of O(n) +DATA: lt_kna1 TYPE HASHED TABLE OF kna1 WITH UNIQUE KEY kunnr. +SELECT * FROM kna1 INTO TABLE @lt_kna1. + +LOOP AT lt_documents INTO ls_doc. + READ TABLE lt_kna1 WITH TABLE KEY kunnr = ls_doc-kunnr INTO ls_kna1. +ENDLOOP. +``` + +✅ **Consolidate similar SELECTs:** +```abap +" Instead of 3 SELECTs, use 1 +SELECT SINGLE name1, land1, stceg FROM kna1 + WHERE kunnr = @lv_kunnr + INTO (@lv_name1, @lv_land1, @lv_stceg). +``` + +#### 5. Use Modern ABAP Syntax (7.40+) + +✅ **Inline declarations and VALUE constructors:** +```abap +" Modern syntax +DATA(lt_result) = VALUE tt_vat_header( + FOR IN lt_bkpf WHERE ( blart = 'RV' ) + ( bukrs = -bukrs belnr = -belnr ) +). + +" String templates +DATA(lv_message) = |Processing { lv_count } documents in { lv_runtime } seconds|. +``` + +#### 6. Optimize Internal Table Operations + +**Choose correct table type:** +- **STANDARD**: Sequential processing, preserve order (INSERT O(1), READ O(n)) +- **SORTED**: Frequent search with key, maintain order (INSERT O(n), READ O(log n)) +- **HASHED**: Frequent key lookups, no order (INSERT O(1), READ O(1)) + +✅ **Use binary search on SORTED tables:** +```abap +DATA: lt_mara TYPE SORTED TABLE OF mara WITH NON-UNIQUE KEY matnr. +READ TABLE lt_mara WITH TABLE KEY matnr = lv_matnr + BINARY SEARCH " O(log n) instead of O(n) + INTO DATA(ls_mara). +``` + +#### 7. Add Appropriate Indexes + +**When to create secondary index:** +- Table has > 10,000 rows +- Query accesses < 20% of rows +- WHERE clause uses same fields repeatedly +- ST05 shows "table scan" warning + +**Index design guidelines:** +1. Always include MANDT first +2. Most selective field second +3. Maximum 5-6 fields +4. Match WHERE clause order +5. Test before/after with ST12 + +**Example:** +```sql +-- For query: WHERE bukrs IN s_bukrs AND stmdt BETWEEN ... AND mwskz IN s_mwskz +CREATE INDEX zbset~001 ON bset (mandt, bukrs, stmdt, mwskz); +``` + +### Post-Optimization Validation + +✅ **Performance comparison:** +``` +ST12 → Measure original vs AMDP +Compare: Runtime, DB time, # SQL statements, memory +Target: 5-10x improvement, 99%+ reduction in SQL calls +``` + +✅ **Functional validation:** +```bash +# File comparison +diff <(sort VENTES_ORIGINAL.txt) <(sort VENTES_AMDP.txt) + +# Amount reconciliation (must match within ±0.01 EUR) +grep '^E' VENTES_ORIGINAL.txt | awk '{sum+=$24} END {print sum}' +grep '^E' VENTES_AMDP.txt | awk '{sum+=$24} END {print sum}' +``` + +--- + +## Best Practice Reference Resources + +### Official SAP Documentation + +1. **AMDP Documentation** + -
