QM Implementation

Hello QM Superiors,

I have some queries regarding QM procedures,

For inspecting material with material specification, we need to perform these transaction:

MM01, QS21, QS61, QA01, QA32.. is the sequence is right..?

If the sequence is right, then what is the use of QS41 and QS51 in material specification.

Please clear my doubt and elaborate the same. Thanks in advance

Regards,

Santosh
