SAP IBP Heuristic - external source of supply

[ydyulgerov]

Hello everyone,

I am facing the following issue after heuristic run in IBP (time-series based planning):

I have correctly maintained the BOM structure under 'Production Source Item' MD in IBP. I have one FG, two SFGs and several components all of which are externally procured, i.e. there is no inhouse production.

Under 'Production Source Header' MD I maintained production source ratio = 0 and a source type 'U' for all Product ID / Location ID / Source ID combinations , whereas the Source ID is equal to the vendor ID.

Under 'Location Source' MD Location Source Ratio = 1 for all my Product ID/Location ID/Ship from Loc. ID combinations , whereas the Location ID is my plant and Ship from Loc. ID is my vendor ID.

Currently, I have no receipts generated and I can not see the component demand under the components sheet of the S&OP Heuristic planning view. I only see my Outbound Location Demand for my FG from my vendor ID to my Location ID. I would like to have the component demand as well as the receipt generated for all the products.

I guess I have missed some master data settings and adjustments, but any help will be highly appreciated. Thank you very much in advance.

BR,
Julian

Hello yuliyand

Since you have maintained production source ratio = 0 hence heuristic is not generating any receipts, as it is unale to identify any valid SOS. Maintain production source ratio = 1 and you everything will work as desired.

Screenshot is missing.

In case you dont have in house production. then you should not have any production source header or item maintianed at any in house location. For example you have FG1, which needs SFG1 and SFG2 as components and lets say SFG1 needs RM1 and RM2 to be manufactured.

In IBP vendor location has to be treated similar to plants. So FG1 will be sourced from V1 (vendor A) and V2 (vendor 2) equally. So for this you need to have source location MDT maintained like V1 >>>>>> DC1 location sourcing ratio & TRATIO as 0.5 and V2 >>>>>> DC1 location sourcing ratio & TRATIO as 0.5.

Now at V1 and V2 you should have production source header & item maintained where you should update the RM1 and RM2 and all other components that you need from V3(Vendor C). Also you need to maintain source location as V3 >>>>> V2 and V3>>>>V1 with location sourcing ratio & TRATIO as 1.

You cannot use source type U because if you mention U heuristic or optimizer dont even look at production source item MDT and hence dependent production demand for components wont be generated.

Hope this helps

Hello ayanbishnu1981,

I saw your comment. Screenshots were attached as additional answer.

Istn't TRATIO and Location Source Ratio the same thing? There is an attribute ID TRATIO with description Location Source Ratio assigned to MD 'Location Source'.

Here is my last changes of the MD, unfortunately I am not able to get the results. I really do not know what I am missing:

The idea is that we have plant 1010. The FG is produced and delivered by vendors A and B equally. The SFGs are produced and delivered by vendor C and the RMs are delivered also by vendor C.

I would really appreciate your help.

BR,

TRATIO and Location Source Ratio are the same. But TRATIO is Attribute and Location Source Ratio is a KF.

Please try the following

1) Production sourcing ratio for FG at Vendor A and B change the value 0.5 to 1 for both the entries.

2) Mark the source type as P for everything.

3) Refer to row no 33 and 34. make the corresponding TRATIO and /or Location Source Ratio as 0.5 for both the entries.

Let me know if that works. In case it doesnt work, run the S&OP operator in check mode and share the aplication log for the same.

Hi Ayan,

I managed to resolve the issue by simplifying a bit my testing scenario. I have now one FG and all the components connected to it. In the production source header MD I have only the FG. Within the production source item MD is the product structure as it is. And within the location source MD I have my ship from - location - product combinations with a location source ratio of 1.

Thank you very much for your help once again.

BR,
Julian

I am glad that it helped.

Hello Ayan,

Thank you for your fast reply. However, I think I modelled it as it has to be but unfortunately I still can not get the receipts and the component demand. Hereby I attach a screenshot from my master data. It is assumed that FG will be delivered by vendor A or vendor B (equal proportion) and all other SFGs and RMs will be supplied by vendor C:

Production Source Header:

Production Source Item:

Location Source:

BOM structure:

Thank you very much in advance!
