Can you please elaborate the each one in detail?

Hi,

In simple words

1.what is the meaning of Stock days supply field showing 999,9- (meaning of 999,9-)

No supply proposals exist to meet the demand which is way back in the past. Go to MD04 & check the demand date for this part.

2.what is the meaning of 1st receipt day supply & 2nd RDS

1st RDS is considering the firm supply proposals (PO, SFO etc) how many days will the supply last to meet the demand before it becomes -ve.

2nd RDS is considering less firm supply proposals (eg: PR etc) how many days will the supply last to meet the demand before it becomes -ve.

(Note - 1st RDS & 2nd RDS is configurable, meaning you can decide what the system should consider & what it should not)

3.Exception message group 3 showing the value 19 (In message group 3 there is no 19)

It means there are 19 supply proposals having exception messages which belongs to exception group 3.

Hi Vivek,

Thanks for immediate reply.

Can you please explain me what is the main difference between 1st RDS and 2nd RDS?

Hi,

The main difference would be what you consider as available for the calculation. You can configure in OMIL.

Pasting SAP help, which explains it quite clearly:

The receipt days' supply indicates how many days a material will last. The system takes current plant stock and specific, predefined receipts into account when calculating the receipt days' supply.

You can define two receipt days' supplies.This enables you to instruct the system to take the less binding receipt elements into account for the first receipt days' supply, and to take only the binding receipt elements (such as production orders and shipping notifications) into account for the second days' supply.

Additionally, in Customizing for MRP, you can use the safety stock indicator to define whether the number of days refers to the safety stock or the actual physical stock.

If the number of days is based on the safety stock, which is set in the standard settings, the system calculates the number of days until the stock level falls below the safety stock level. If the number of days is based on the physical stock level, the system calculates the number of days until the stock level falls below 0.

Material with critical ranges of coverage are indicated by red traffic lights in the MRP list and the stock/requirements list. You can define how many days are considered to be critical.
