SNP CTM Multilevel finite planning supply issue due to big list of input components

[Former Member]

We have a multilevel BOM scenario, in which a material has an assembly component, which has further children. The children may be supplied by another facility. There are some phantom assembly components also and in total the components can range up to 25 of them. Our experience with SNP CTM (Bucket planning with 2 years horizon) is that many times there are late supply or, no supply at all due to component availability or, long lead time for even one component. We prefer getting planned order on time and any component issue to be resolved by alerts. We understand the short supply/no supply is standard behavior and are considering following options to work with this-

• One of the option for us is to thoroughly check each component as part of cut-over to make sure there is minimum issue of late supply or, short supply.
• Another option may be alternate BOM and PV for SNP usage with critical components and once we convert the orders to PPDS order, all the components will be selected and planned. However, we feel this as a lot of extra work for master data creation and don’t want to opt this.
• Third option may be to use the option of product master as ‘not relevant for DP and SNP’. However my experience is CTM doesn’t respect this setting and still plans. Heuristic though totally ignores the product if this box is checked.
• Last option will be to not take many products in APO so that they will not be there in SNP PDS and hence, will not influence the planning run. We don’t prefer to go in this direction as it has negative potential of not planning at all.

Please suggest your thoughts on the recommended approach. Please suggest if there is any other alternative better option possible which is not mentioned here.

you should ask yourself why use CTM in the first place?

Multiple reasons, which make a strong case for CTM. The major ones are demand priorities, finite capacity planning, rules based supply etc.

CTM serves the business needs. Only issue is, for multi level BOM components, planned orders are getting delayed or, not getting created at all for any component shortage. We CTM to still create the finite supply plan and business can take action on component shortage (if required) through information on shortage alert.

If CTM can't do this, then we will go either with alternate SNP BOM or, very thorough data check. But, need to understand if anybody else has handled this through another innovative approach.
