In our warehouse, stock is available in reserve storage types, but the picking bin becomes empty or falls below the minimum quantity. The expected replenishment warehouse task is not created, which can affect outbound picking.

I would like to understand the complete replenishment process and the required configuration.

Please help with the following points:

• What is replenishment in SAP EWM and why is it used?
• What is the difference between planned replenishment, automatic replenishment, order-related replenishment, and direct replenishment?
• What master data is required for replenishment, including fixed bins, minimum quantity, maximum quantity, and replenishment quantity?
• How can we configure a storage type for replenishment?
• How does SAP EWM determine the source storage type and destination picking bin?
• How do warehouse process type, storage type search sequence, and stock removal rule affect replenishment?
• Why is replenishment not triggered even when the picking bin is below the minimum quantity?
• Can open warehouse tasks, blocked stock, stock type, or capacity checks prevent replenishment task creation?
• How can we run planned replenishment manually and schedule it as a background job?
• Which transactions and /SCWM/MON nodes should be checked for replenishment errors?
• What are common configuration mistakes and real-time troubleshooting scenarios?

A step-by-step guide with SAP EWM configuration paths, transaction codes, practical examples, and troubleshooting tips would be very helpful.
