How to handel material locking in WM

Question

Dear Experts
Our warehouse is managed by warehouse management and we face a problem  when one of the stock keepers  post goods issue with reference to sales order from the warehouse  while another on is performing a goods receipt at  the same time  and the same batch the system issue the following message
Batch xxx of material y is already locked by user
Message no. M3682
Diagnosis
You want to process a batch that is already being processed by another user.
System Response
A batch cannot be processed by more than one user at the same time. To prevent data inconsistencies, the batch record is locked for processing.
And this locking cause a delay to our work
So is there any way to solve this problem  in the warehouse management so that the 2 stock keepers can do their work in the same time without locking
Best Regards

Answer 1

you check Note: 1949813 for Message M3682 "Batch & of material & is already locked by &" in transaction MIGO, VL32N and VL02N.
Solution:
Both BAdIs have to be implemented and must be active
BADI MATERIAL_READ method LOCK_BATCH_MASTER
BADI BATCH_MASTER method LOCK_BATCH_MASTER_IN_MIGO
Step 1:
go to OMJI to Activate late lock for goods movement
step 2 assign Methods
Activate BADI BATCH_MASTER for method LOCK_BATCH_MASTER_IN_MIGO
method IF_EX_BATCH_MASTER~LOCK_BATCH_MASTER_IN_MIGO.
   C_LOCK_MODE = 'S'.
endmethod.
Step 3:
go to SE18 Activate BADI MATERIAL_READ for method LOCK_BATCH_MASTER
after that test 3 user make goods movement for the same batch, same plant and in the same time you can post goods movement Successfully.
Test Goods movement through MIGO, VL32N and VL02N, all user post Successfully.
