2. Click on the Posting Button.
3. Select "Unallocated Entries" option.
4. Press "tab" on the keyboard twice.
5. If no allocations are to be done on this entity, click the 'Next Entity'.
6. Allocate the unallocated entries of the current entity.
7. Update the allocation.
8. Click the 'Next Entity' to load entries of the next entity that has unallocated entries. 9. Repeat Steps 4 to 8.
