Hi
Strange.
You have the reference straight up there. Have a look at the marketing attribute AB.
The 'Value' column drop down is dependent on 'Attribute set'. You can't find a better example than this. Look at how they have done it in standard.
BSP: BP_DATA/MarketingAttributesEOVP Context: Attributes Attribute: Value_descr
If are still not able to solve it, give me the value of LV_PRODUCT for both line item. You can get it by keeping the breakpoint in get_v method of field 2. Also, the code of it.
