Queries regarding reorganisation of PIRs

[Former Member]

Hi PP Gurus,

I have some queries related to re-organization of PIRs using MD76.

1.In order to execute MD76,we first need to execute MD74 and MD75.Execution of MD74 has two parts.

a) Adjustment (reduction) of all planned independent requirements scheduled quantities to the amount of

(customer) requirements assigned. If no requirements are assigned, the planned quantities are set to

zero.

1) what does planned quantities being set to zero mean?

2) what is the amount of requirements assigned, where can we find it in table

b) For all inactive requirements (these have no requirements assigned), the schedule line records are deleted from table PBED if the 'Delete inactive requirements' flag is set on the selection screen.

1) What makes a requirement inactive?

2) When do you actually Plan PIR?

3) When will they be inactive?

2.When we say planned qty in PBED, is it PLNMG, or FIXMG field.

3.Which field in PBED is for schedule lines?

4.I found that in PBHI under history field,some entries have data as 00000000, what is the significance

of 'history' being zero.

Kindly clarify my doubts.

Hi Mary Joy,

1) what does planned quantities being set to zero mean?

The planned quantity set to zero mean the adjustment of an PIR. ie this function is used to adjust the qty of a PIR by reducing the open quantity to zero. The open quantity is the original planned quantity that has not been consumed by orders of other categories, usually sales orders. Alternatively you can delete such an order completely.

2) What makes a requirement inactive?

Requirements are made inactive via many factors like change in demand, change in pegging conditions, change in sourcing, change in forecast, changes in sales orders, scheduled line, inconsistency of data, changes in customer demand, Fresh release of plan etc.,

3) When do you actually Plan PIR?

PIR's are demand or requirements that are generated from a firm customer orders like sales order, forecast, scheduling agreement etc., PIR can be either entered manually in system or transferred from other sources

4) When will they be inactive?

As and when if a customer demand changes, or if a PIR is deleted or a fresh PIR is overwritten, then the previous PIR will become inactive
