# NEXT2 - Multi-Line Search Implementation
## 1. New Support DB
```pascal
DATA_BLOCK "10_NEXT2_Support_D"
{ S7_Optimized_Access := 'FALSE' }
VERSION : 0.1
NON_RETAIN
STRUCT
LineN : Array[0..5] of Struct // Same array size as 10_SkuManage_D
i : Int; // Search index (synchronized with 10_SkuManage_D)
ReqNext2CustomProdNum : String[12]; // Requested NEXT2 product number (from IDH_BTL_NEXT2)
OldNext2CustomProdNum : String[12]; // Previous number to detect changes
SearchNext2Sku : Bool; // Active search flag
SkuNext2NotFound : Bool; // SKU not found flag
SkuNext2Req { S7_SetPoint := 'False'} : "StSku_U";
END_STRUCT;
END_STRUCT;
BEGIN
END_DATA_BLOCK
```
## 2. Changes to FC11 (10.01_SkuManage_G)
