MRP run with stock transport orders: dates calculation

[Former Member]

Hi Gurus,

My situation is as follows:

Plant A: only trading goods.

Materials are supplied from another plant B (same company code) through stock transport orders. Then plant B is the supplying plant of plant A, and I made the stock transport configuration to allow this.

Plant A:

MRP run on 16/12: stock quantity is below the safety stock -> new requirement : Automatic PR creation with plant B as supplying plant.

MD04: receipt date is D date + delivery date

In my example: 16/12 + 1 = 17/12

Plant B:

A PRqRel is visible in MD04 accordingly to the PR.

No stock available in plant B to cover this PR.

MRP run on plant B on 16/12: an automatic PR is created (which will be converted to a standard PO).

MD04: receipt date is D date + delivery date

In my example: 16/12 + 3 = 19/12

My question:

I would assume to receive a new date for this material in plant A because my material will only be available on 20/12 (19/12+1).

I run MRP on plant A again, and nothing change: still have the receipt date : 17/12.

I would have expected to get 20/12 as rescheduling date or any information to inform plant A of this new date.

Is it possible? Did I miss something in my settings to support this?

Thanks a lot in advance.

Hello

MRP does not carry out an availability check on the supplying plant, it simply creates the requirement.

Therefore, the date on the delivery plant is not changed if there is not enough material on stock.

Hello Caetano,

Thank you for your reply.

Is there any list or report, or any tools for the planner to be informed about this kind of delay?

C,

MD06 is a collective display of messages from the MRP runs.

You can set MD06 to highlight only the messages that interest you.  In your case, you will probably want to see certain messages in the supplying plant.  These messages will probably include '10 Bring process forward'.

Thanks for your reply.

I would like to come back to my original request.

I noticed a setting in stock transport order customizing, in Assign delivery type and checking rule: ATP "Confirmations Relevant for MRP".

Caetano, you told me availibility check is not possible on the supplying plant. But it seems this setting allows it. Do you know more about this parameter? Don't you think this could be an answer?

Thx.

C,

Caetano, you told me availability check is not possible on the supplying plant.

No, he did not say that.  He said MRP does not carry out availability check.  Availability check is unrelated to MRP processing.  Confirmations can be set to be relevant (or not relevant) for MRP net requirements calculation, as you have noted.

Availability check is another subject altogether.

Best Regards,

Hello

This is available for stock transport order, not for stock transport requisition, right?

MRP does not carry out any kind of ATP check when creating stock transfer requisitions.
