Hello Liang Ji,
In short:
- in WebUI press F2. Note down component,view, context node, attribute.
- in SAP GUI go to transaction BSP_WD_CMPWB, enter component, go to your view and context node. Note down the BOL-entitiy.
- in SAP GUI go to transaction GENIL_MODEL_BROWSER, search for your BOL-entity and search the database table, eventually with a where-used-list.
Best regards,
Thomas Wagner
