GHCL Limited faced several challenges after implementing SAP, including frequent changes in management and business processes. To address this, they standardized costing calculations and created a generic process flow model. They also automated data entry through interfaces to reduce errors and delays. Data entry positions were eliminated and existing employees were reassigned. Transactions that allowed adjustments or disturbances were locked down. Key transactions were gradually transferred to authorized users with training on user-friendly screens. These approaches helped simplify the system and provide error-free data analysis to decision makers.
