Dear VGR,

The requirement type refers to the origin type, for example, goods receipt for purchase order (Type B) or goods issue to cost centers (Type K).

The criterion that groups together all checking rules for all application areas for a material.

In conjunction with the checking rule, the checking group defines the scope of the availability check for each business event, that is, which stocks, goods receipts, and goods issues are taken into account in the availability check, and whether replenishment lead time is checked.

Checking rule

A rule that defines how the availability check is performed.

The checking rule, in conjunction with the checking group, determines the scope of the availability check for every business operation; that is, which stocks, receipts, and issues are included in the availability check and whether the check is performed with or without the replenishment lead time.

I hope this will help you,

Regards,

Murali.

Thanks a lot Murali but still have a doubt where does the term req. class comes into play?

It is linked with the following:-

- In material master MRP3 view, see what strategy group is maintained.

- Go to OPPS, select your strategy group and see what Requirement Type is maintained there.

- Then go to OVZH, select that Requrement Type and see what Requirement Class is maintained there.

- This Requirement Class settings can be modified in OVZG according to the requirement.

thanks
