Customer stories

Healthcare

Kwangdong Pharmaceutical

Kwangdong Pharmaceutical is a healthcare (pharmaceutical) company that develops pharmaceuticals, beverages, and health functional foods.
Impact
Impact
  • Reduced time spent on querying and analysis
  • Increased efficiency in formulating sales strategies due to fewer repetitive tasks
Challenge
It was necessary to establish daily and monthly sales strategies based on SAP ERP data, but since the ERP system was limited to query-oriented functions, the data had to be downloaded and manually processed for necessary analysis.
Solution
We have developed a chatbot based on sales data linked to the SAP ERP system. Users can now perform tasks by automatically generating SQL when querying in natural language, querying the DB, and providing processed results.
Result
Reduced manual analysis time of sales data and reduced repetitive tasks. Real-time data accessibility and work efficiency for establishing sales strategies have been improved together.
