Stock Differences in HU (Handling Unit)

This blog post might help you to solve the problem with these messages.

• HUGENERAL 017 Handling unit &1 has the status "goods issue posted", cannot be changed
• HUFUNCTIONS 251 No posting-relevant material items could be found

Many times it happens that the standard functionality provided by SAP is not sufficient. IN HU if customisations have been done, it is possible that, you end up with some data inconsistancy. The worst part about this is that not much is available in SAP or even internet. I learnt these hard way. The solution might look very simple, but it has consumed quite a lot of tense days. This could be due to some MDE customisations also. The above messages might appear if you are trying to transfer HU from blocked to unrestricted or vice versa using VLMOVE. Or if you are trying to pick a HU from stock. What happened in my case is that the inventory stock was transferred to Blocked stock, but the HU was not updated. So, the following standard transactions gives an error.

• Pack the stock in blocked stock
• Stock adjustment (neither in HU nor in blocked stock)
• MIGO to transfer from blocked to unrestricted
• Physical inventory

Enough of the story. The following step by step instructions will correct this

1. Execute SAP program RHU_STOCK_DIFFERENCES. This will correct inventory stock based on HU. So this will add inventory stock in the unrestricted qty equal to HU qty.
2. Once this is done. using VLmove move the hu from unrestricted to blocked stock.
3. Now blocked inventory stock is more than that in HU. execute RHU_STOCK_DIFFERENCES again. THis will clear the excess inventory stock.
4. Move the HU from blocked stock to Unrestricted.
