Material master blocking

Dear all,

This issue is regarding of material master.

We have following type of plant sp. status for blocking

1) Z1 - Blocked for proc. allow issue

2) Z2 - Incomplete documents

3) ZT - Total block status

Till date these key were satisfying our need but now there is a situation which cannot fulfill by above keys. Take a look -

Requirement is material should been block in such a way, that it should allowed for issue, production but not for proc. in such case if I use Z1 it can be possible but, we require that what already created purchase order in system also must not allow for GR.

It can't be achieved by Z1 and Z2. If i use ZT - total block, it is possible, but again it blocks the inventory hence not allowed to material issue.

I have created a new key in OMS4 but when i set error msg in inventory mgt. field it not allows Issue and if set warning msg. then system allows migo for existing or already created PO which is very thing I want to block.

As this will be the regular process, i can't lock material in Purchase order as volume of PO is more.

Please refer a screenshot of newly created key.

Please suggest.

With best regards,

Manish K. Bachate
