Impact of period lot size on planning time fence

Former Member

Hi All

Can anyone explain why does the period lot size setting of a material affects the planning time fence of the same.

For example,

Material period lot size is MB(i.e monthly lot size) and the planning time fence is say 10days and suppose the MRP is run today(14.07.2008) i see that the end of planning time fence falls as 01.08.2008 instead of (14.07.2008 plus 10 working days i.e 28.07.2008).

Hi,

There are some OSS Notes related to your issue.

1. Note 40681 - Planning time fence and period lot size

2. Note 64734 - Firming procedures 2 and 4

3. Note 663449 - Planning time fence for periodic lot sizes

4. Note 148246 - Move planning time fence, lot size

In all the cases SAP is advising for Source Code corrections.

Pl. gothrough..

Regards,

Siva

In the Spro OMI4 MRP Lot Sizing Procedure for MB Monthly lot size

there is a setting for Scheduling

Scheduling 1 Period start := delivery date

Here even though our requirement will come on mid or any of the days in that particular month

System will take Month Start Date ie) 1st as Delivery date (Requirment date)

It is modifyiable

Hi Lakshmana,

What I think is the Monthly lot size will consider always the beginning of the month or the end of the month.

Thanks and regards
