Create Handling unit after receiving finished goods from production

Hello,

My client's requirement is that they do not want a TR or TO to get created at the time of Production order confirmation and neither they want to create the Handling unit at the time of confirmation.

They want to move the material from production to warehouse as one Handling unit after multiple confirmations. They want to create Handling unit manually after the receipt of materials.

What is the process of creating Handling unit after we have FG (multiple batches).

After creation of Handling units, my client wants to ship the same Handling unit out to customer.

How to create Handling unit

Regards
