TM purchasing organization vs MM purchasing organization

[floris2310]

Hi everyone,

I'm working on setting up TM in an embedded S/4 1809 environment. However, I'm having trouble with the definition of the purchasing organizations in MM and TM and the effect on masterdata.

- Should the org structures always be aligned between MM and TM? In MM we have general 1 purchase org. (A001) and multiple company codes (C010/ C020) below it. In TM, I understand the rule is to have you purchase org. below the company code. So in TM I have, C010 with A010 and C020 with A020 although in reality there is only 1 purchase organization.

- I'm concerned about the impact on invoice integration in ERP. What are the consequences?

- On the carrier business partner, CRM010 role, you assign the purchasing organization. I assume this is the MM purchasing organization? Not the TM one? And further, if my carrier is defined within MM purchasing org (A001), will I have trouble creating for example a freight agreement with the carrier within a TM purchasing org (A010).

Thanks for your input, it is kindly appreciated!

Hi Floris,

in my S/4 Hana TM implementations, I create 2 different purchasing organisations for MM and TM. But, I still have to have a logic wich allows the assignment of the ERP purchase org (see below).

Reason: I do not want to interfere with MM and there is no obligation to use exactly the same logic. I create a separate company organisation for TM, i.e. TM-Company, then I create the TM purchase orgs below the company (see FRANCE in below picture). Very often, I will use the country, especially for international companies.

The vendor needs to be created for the MM purchase organisation for PO creation. For TM, you need the role Carrier. This is necessary to create the freight order.

When transferring the FSD to MM to create an automatic service PO, you need to assign the related MM Purchase Org in PPOME (as created in the usual SPRO path create purchase org). This assignment to the ERP Purchase is done within the screen in PPOME (see below P010). the field has the explanation in the f1 help. but, the name BSG Org unit is not very clear. Hope this helps

Hi Petra,

Your solution worked for me. I maintained "BSG Org Unit" field with ERP Purchase Organization and it resolved the issue.

Tack så mycket!
