block planning in apo

[Former Member]

HI,

I am trying to setup block planning (tried also without configuration) using ppms in apo.

the main issue is to be able to plan on one machine the production in periods in which e.g. in week 24 only products with mrp controller 3 can run, week 25 only products of mrp controller 4, then week 5 to7 all products, then again products for mrp controller 3 can run.

I have created the characteristics, classes and assigned the class to the resource and created the blocks. I assigned the classes also to material master data but would like to avoid it, so the products will not be classified and hence while creating sales orders / purchase requisitions in snp area no pop up with the characteristic valuation appears. I assigned the classes to ppm.

Now when I plan I cannot get all the products in the block in which all products can run. All the planned orders go to the blocks which are specified only for products of one mrp controller. in the material master data, tab classification, and ppms I defined two characteristic value: 1. all .2. mrp controller nr e.g. 1..

I defining block in the resource nr 10 for all rpdocuts: value all. Hence I expected the system would generate planned orders for all products in that block. But when running product heursitic in ppt or "schedule by start time" heuristic in the graphical planning board, I cannot schedule any orders in the blocks for all products.

can someone help me with?

how can I setup the block planning without using configuration?

thanks in advance,

WSH

Hi Claire,

thanks.

I followed the steps before publishing my questions but could not activate the ppms if the product was not classified and I used standard values. I do not activate standard valuation as I was doing that before and I could not activate the ppms afterwards.

my next question is how can I update ppm in a mass way with the characterisitc propagation

instead of doing it manually?

at the moment I call up the ppm via plan / use characterisitcs propagation / use . the system checks on which resource the activity p runs and which class is assigned to. then it assigns the class to the activity p in the ppm automatically.

in hte next step I only define the std valuation in the pop up "Default value assignments for component P /xxx) (click on the push button "Std Valuation" in Details of components) .without activating the check box "set value assignment ".

this I  would like to do i a mass way but don't know how.

thanks anyone for help!!!

Hi Frank,

thanks. I went through the notes, also 1302074 & 1304170. Will see if I can use them.

we are not using products variants so I only want to classify the activities in ppms in apo.

That means that I create the characteristics & classes in r3, transfer them to apo, assign them to resources and then update ppm with the characteristic propagation.

While updating the characterictic propagation, I enter as standard value the mrp controller code which is the basis for grouping products on machines. this I would like to update via e.g. massd or any other report. that means that I need the field of standard value to be able to enter the mrp controller code.

thanks for you hints!
