MB1A - how can search material by material number quickly??

In our company ,When post goods issue for production order with MB1A, people have to change quantity for some items. But if I want to find certain item, I need page down or page up to find this item,but there many components some times more then 100 in one production order, this is very large workload. And when use position cursor function,we could only find the item by the item number,it is helpless.

By the way ,I know use MIGO to production order ,we can search material easlily！But for authorization purpose ,because MIGO can do more than MB1A, we restrict MIGO not to use goods issue for production order.

How can search material by material number quickly in MB1A?By what ways?

Or search the material by the material number by some ABAP development?Are there any user exit fit this?

Or are there any other third party software can help do this?

Thanks for any reply!
