Hallo Daxer
please check this link:
docs.microsoft.com/.../project-resourcing
excerpt:
When you set up a worker as an intercompany resource, you must complete the setup in the lending company and the borrowing company.
In the lending company:
1.In Finance and Operations, verify that the lending company is selected, and then complete the procedure above, "Set up a worker as a project resource."
2.Go to General ledger **> **Posting setup **> **Intercompany accounting. Click New.
3.In the Legal entity ID **field, select the lending company. Fill in the remaining fields as appropriate, and then click **Save.
4.Go the Project management and accounting **> **Setup **> **Prices ** > **Transfer price.** **
5.On the Transfer price **form, click **New, and in the **Borrowing legal entity **field, select the appropriate company.
6.If you want to only loan the borrowing company the resource that you created at the beginning of this section, in the Resource field, select the name of the resource that you created. If you want to make all resources in the company available to the borrowing company, leave the **Resource **field blank.
7.Go to Project management and accounting **> **Setup **> **Project management and accounting parameters, and on the Intercompany **tab, set the **Enable intercompany resource scheduling and timesheets **field to **Yes.
In the borrowing company:
1.Go to Project management and accounting > Project resources > Resources list.
2.In the search filter, enter the name of the resource that you created in the previous procedure for the lending company to verify that the name is included in the resource list for the borrowing company.
i got it up and running for our Company following that
what you have to additionally take care of is the creation of a procurement hierarchie and node (for the Project category that is then attached to the procurement category)- which is then selected in the intercompany Settings in the Project Parameters
