...les_share < 0.8, "A", if_else(Accumulated_sales_share < 0.95, "B","C"))) So, here we come to the main problem: i need to add 3 more columnes with the SKU statuses: if the the SKU is in top 20% of clients sales by Cost, Gross_income and Profitability, than it is a "cGSKU" (clients gold SKU) if the SKU is not gold, but occurs in 50% of transaction IDs with cGSKU, than it is a "cMSKU" (clients must have SKU). So i dont know how to realize this. I think it must be some cind a cycle. Could you please help me...
